Testimonials

Since Yooch joined my team as the Senior UX designer in late 2021, I have been working very closely with him on building the end to end user journey for Insight Investment's new trading application.

His depth of experience in UX design and understanding of users' real needs are phenomenal. He was a valuable contributor to the team and project from the very beginning.

He has an easiness to building excellent interpersonal relationships with team members as well as FO business users, such as traders and fund managers.

He really values the user centric design approach and actively promotes the key design principles during the project and through an inspiring workshop hosted by him.

It is rare to find a highly experienced creative talent like Yooch, who has the perfect combination of expertise in UX, great understanding of digital technologies, as well as in-depth knowledge of the financial industry.

Yooch is a real joy to work with, I will recommend him highly without reservation.

I worked with Yooch building a new buy side OTC derivatives trading system. Yooch was responsible for UX engineering.

I had a very good experience working with Yooch. He is passionate about producing best in class UX at the same time is very reasonable about what can and can't be achieved by a team of developers during each of the iterations.

He also has a good grasp of modern product and software development methodologies and understands UX role in both very well.

The system that Yooch was in charge of UX for was received very well, adoption experience for users was smooth, which I believe is due to a well thought through user experience.

Yooch and I started at Insight around the same time, and I have the pleasure of working with him building a new platform called Order Modelling and Dealing. The platform is being developed to allow Dealers and Portfolio Managers to create multi-asset order packages, view pre-trade prices using quotes from Bloomberg and view various risk metrics all in real time.

From early in the project, it was evident that Yooch is a highly skilled and creative designer with a deep understanding of user-centered design principles. He has great ability to deconstruct complex problems and turn them into intuitive and user-friendly interfaces that are visually pleasing, easy to use, modern, and effective.

Yooch has strong background in finance and has good technical knowledge in the current web technologies. This helps him see the implementation challenges and he goes the extra mile and provides working version of his designs using HTML, CSS, and JavaScript.

Yooch is a real pleasure to work with, he is always cheerful, very collaborative, has time to hear others' opinion and takes any comments from team members positively.

I have had the opportunity and pleasure of working with Yooch since April 2022, and have found him to be very professional, knowledgeable and collaborative.

He brings vast experience to his projects and executes them diligently, displaying a real understanding of the design lifecycle and how it fits within overall product development.

It is a real pleasure learning from and working alongside him!

Yooch is a stellar designer and a complete joy to work with. He is extremely knowledgeable when it comes to designing financial applications, particularly when it comes to solving complex UX problems like catering to nuanced cognitive processes of end users.

The thought processes of portfolio managers, traders, and customers when they analyse financial data; their immediate goals and any hidden attitudes and fears, are all subtly reflected in Yooch's designs.

Although he is already stretched across multiple projects, Yooch was kind enough to make himself available when our team didn't have a designer. After just a conversation and a brief walkthrough of my half-finished user research, Yooch was inspired and went off to create a Blue Sky Thinking sketch that not only comes close to solving the main user problems, it's so good that it has the potential be white-labelled!

I cannot recommend Yooch enough :-)

Yooch has been such a supportive and impactful colleague, always making an effort to create a great team culture — or maybe it’s just his natural talent. He’s definitely one of the key figures holding the team together.

He’s super active in sharing knowledge, whether about work or his life experiences, and that makes a big difference for everyone around him. Regarding his area — UX — he’s incredibly reliable, always producing practical and thoughtful solutions. Everything he delivers is backed by his years of experience and solid professional expertise.

Working with him has been a genuine pleasure. Working alongside someone so passionate and dependable has not only been inspiring but also a highlight of my time on the team.

I have worked alongside Yooch on two different front office product teams, working on Portfolio Management tools.

He has a great ability to break down very complex requirements when building financial tools, and turning them into precise, detailed, and clear designs. He actively promotes a user focused approach to building software, with a great balance between creative design and technical feasibility.

It is also great to have his help as an intermediary when working with front office users- analysts, traders, portfolio managers, etc. As well as his experience in UX design, he has an in depth knowledge of the financial industry, which makes working on complex projects with tight deadlines a lot smoother with him on board!

He often goes the extra mile when providing designs, such as providing HTML prototypes, and is extremely open to feedback.

His overall attitude, depth of experience, and collaborative approach makes him a pleasure to work with!

As a colleague, his humility, kindness and sincerity make him one of a kind.

A professional, reliable, technical UX’er and an all-round good person to know. He went above and beyond in his role working on multiple workstreams, setting up and leading teams diligently and efficiently to create new, innovative design and development libraries.

UX and Product teams made him a 'go to' guy for his depth of knowledge and experience of financial markets and products.

No question was ever too dumb for him to make time for everyone. Testament to Yooch, his personality and his skills, I would not hesitate to work with him again, as I am sure most people in this team would agree.

Thanks to his background as a developer, he has a great understanding of the technical implications through the product lifecycle.

Aside from his domain knowledge, I like how elaborate and thorough his opinions are, and how he expresses them.

Many in the team have been inspired by his ideas when he presented them to us, as they brilliantly combined his design knowledge with first-hand expertise in the financial field.

I am enjoying very much having Yooch as a colleague, as he’s a generous person, a pleasure to chat with, and someone who is genuinely open to hear other people’s opinions (and fun facts!).

Yooch, is a plate spinner extraordinaire, his ability to maintain a detailed engagement with a broad range of activities is what he is best at.

He’s also a detail guy, able to nail down tight specifications and communicate them succinctly back the business.

In the last few years I’ve worked with him on a number of jobs and have to say I’d recommend him, without any reservation.

Yooch is a rock. He is that safe pair of hands you turn to when something needs to get done - intelligently and thoughtfully.

His commitment to quality is matched with his deep knowledge of user goals, his grip on technical boundaries and his ability to translate design intent across non-design teams.

In my time working with Yooch, there was never a constraint he couldn’t work around, find solutions for or help with. He is a patient, kind and personable designer, and he appreciates the graft that is needed to bring capabilities and ambitions of a company together.

If you need a professional and reliable UX designer with great and broad set of skills, great technical background, experience and ability to resolve the most complex design problems, look no further.

Yooch is also genuine, honest and fun to work with. I hired him for two companies already and I'll do it without the shadow of hesitation if the chance comes again.

I worked with Yooch for over 9 months on various projects. I validated his design concepts on some key projects within the bank. They were well received by internal and external users. His designs are very well thought through and intuitive.

He is very professional, easy to work with and an expert in his field. I wish him the best of luck in all his future endeavours.

Yooch is an exceptional designer capable of creating logical and intuitive interfaces for a wide variety of users. He has also shown a strong aptitude for designing in the financial services sector.

Yooch is an all round solid designer, I can't recommend him highly enough. With all my honesty, he's a true gold mine of creative solutions and fresh ideas. He will go the extra mile and surprise you with something innovative and unique.

Apart from being an outstanding UX generalist, Yooch has solid front-end engineering skills too and is comfortable with taking his design ideas further by building proper, fully interactive prototypes. It was refreshing to meet another UXer who's fluent in JavaScript, HTML and CSS.

He's a rare find, a creative thinker with a remarkable combination of skills. Equally importantly, Yooch is an interesting person with a wide range of interests, he's just fun to be around! I genuinely believe Yooch would be a perfect addition to any creative team, I'd never hesitate to recommend him.

Yooch and I worked together on an initiative replacing a pricing application. He designed a prototype that was easy to use and based on initial requirements, which he then iterated following user feedback from interviews he had conducted.

Yooch was easy to work with and reliable, and added value to the overall project we were part of.

As a Product Manager in Fixed Income / Credit, I had worked with Yooch on a regular basis as I was building new applications to replace a series of legacy screens on Credit Default Swaps and Credit Ratings.

Yooch was keen to understand the client workflows and based on this always gave guidance to enhance the user experience by suggesting different controls, or even by proposing quite different approaches at times too. Yooch’s goal was always to think as a user and try to find ways to simplify/facilitate the journey of the user through the app, and simply put, to improve the user experience.

It was a pleasure working with Yooch and I believe he would be a good addition to any design team.

I have nothing but good things to say about Yooch.

Working with him was a pleasure - mostly because every time I needed his help or advice I got just what I needed. A good working style, clear thinking, bags of talent and experience and quick results.

Just what I needed.

I've worked with Yooch on the same team for 2 years and on the same project for 6 months.

Yooch's design outputs are always top-notch with very well thought-through solutions. He is always able to quickly understand a design problem and evaluate different solutions to come up with a feasible one. The combination of his interaction design and front-end development skills also makes him a true asset on design projects. On one occasion he was able to code-up a working prototype of a complex input form for a last minute workshop to make sure we are able to gather useful findings from the end-users.

Yooch is a perfectionist, always demanding 100% from his work. I particularly like his way of solving problems creatively. On a particular project, he was able to convince stakeholders of the severity of a convoluted business process by quantifying it and subsequently proposing a simpler process which gained interest from various teams within the company wanting to use similar methods.

Yooch is a great team player and collaborator. He is always helping out with design critiques and constantly testing his own concepts to make sure they work. His excellent interpersonal skills also makes him a joy to work with and his diplomacy always comes in handy during 'tough negotiations' with multidisciplinary teams.

I look forward to working with Yooch again in the future!

Yooch created an excellent interactive mock-up for a complex requirement around responsiveness. I found him extremely easy to work with.

Where my requirements couldn't be met for some reason he was always very proactive at suggesting other ways of achieving the goals and equally he was open to my suggestions for getting around the issues.

Yooch has been a great member of the team at Thomson Reuters. He is armed with a rock-solid set of core skills, covering interaction and UI design, prototyping and technical work, and the ability to systematically analyse, deconstruct, and improve complex workflows.

His extensive domain knowledge in finance and related areas, and his dedication to understanding new fields, has meant that he's been a key player on some of our most complex work.

The team and our senior product stakeholders around the business always enjoy working with Yooch thanks not only to his fast, efficient delivery, but also to the fact that he's a team player and has a knack for lifting everyone's mood when he's around. I have no hesitation in recommending him to other UX directors and teams.

Yooch, absolute professional, joined our project team, came up to speed quickly with the Product Solution being developed and contributed straight away helping us resolve the direction for the UI which had been floundering.

In my role as scrum master I was pleased Yooch integrated quickly with the Team and with our agile process, not easy to do when the Team was spread across UK, US, France and Poland.

His work ethic was second to none, working flexible hours to enable effective working with the remote teams. Bringing both innovative ideas and trusted design methodologies to the project was key to the final product UI which received high praise from our end Client.

It was a pleasure work with Yooch and only due to internal politics were we unable to retain him on the project which was seen by all involved as a real shame.

During the period that Yooch and I worked together at Pitney Bowes I found him to be an invaluable addition to the team.

Yooch is an excellent UX designer with extremely high work ethics and professionalism.

I would not hesitate to recommend him to anyone.

I met Yooch on my last project and soon realised that this calm and collected individual is a powerhouse of UX talent. He is truly creative and adds value to every aspect of UX project delivery. A thorough professional and someone who is a practitioner in the science of UX.

The time I worked with Yooch was a pleasure, his commitment and quality of UX work was always of the highest standard.

He was a key member of the team and I would not hesitate in recommending as a multi-skilled UX'er in any environment.

I worked with Yooch within the Client Portal team for four years after he transferred teams from Fixed Income, Rates & Currencies, where he was instrumental in implementing a new visual design and building the award-winning FXWeb research and analytics portal.

Yooch was responsible for further developing this new visual design language and rolling it out across other web applications across the Investment Bank and was our resident subject matter expert on emerging web technologies, web standards, accessibility, interaction design and usability best practices.

He regularly conducted usability and accessibility reviews for these applications, proposing revised user journeys and suggesting UI improvements where necessary. He worked hand-in-hand with business IT teams to ensure their applications would adhere to the new visual design standards, establishing design patterns and best practices.

He was also responsible for providing technical expertise and support for the Global Communications & Marketing team where he managed several corporate website and corporate intranet redesign projects from a front-end design and development perspective. He also established procedures for day-to-day management and maintenance.

Yooch is passionate about industry news and trends and always enthusiastic when sharing his knowledge with myself and the rest of our team. He was the first to introduce CSS sprites into the corporate website and has been a huge advocate of the use of jQuery and was demonstrating its power years before approval within the bank.

Yooch consistently demonstrates he can:

• design clean user intuitive web applications, conforming to brand guidelines and any inherent restrictions
• pays the highest attention to detail in every aspect of the project, from optimum graphics, to semantically correct code and accessibility
