Working full-time as a product designer and frontend engineer last 5 years in two startups caused my portfolio is rather short. On the contrary, I experienced all stages of design systems – creation, maintenance, and refactor. Therefore, I am wiser now and know how to create scalable design systems that are easily changeable and reusable.

I have experience with low-fidelity and high-fidelity interactive prototyping in both Adobe XD and Figma. I can build the components in React or Angular and adjust the styles in Sass. I can implement events logging to Google Analytics to know how UI is used. If desired, I can create short animations or promotional videos in Adobe Premiere Pro or any other graphical oriented tasks.

As a product designer, I’ve been responsible for the redesign of the VIVIDI platform. Specifically, its design system definition, design and prototyping of new UI components in Adobe XD, product features management, knowledge base maintenance, website WordPress maintenance and occasional React frontend development of the platform. Besides that, I define issues for the new features for the frontend team and make sure that the features behave and look as designed. To track how users interact with the UI, I implemented Google Analytics events tracking and Hotjar recordings to unveil UX flaws and bugs.

As a Fronted UX developer I designed and implemented the first MVP of the product GoodVision Video Insights Platform. The platform is used by traffic surveyors and modellers to automatically collect and analyze traffic data from existing video sources. Therefore, I needed to handle the display, filtering and reporting of the complex spatio-temporal data of detected vehicles so that user could easily understand what he/she sees.

Subsequently, I managed the prioritization, design and development of the new features into the platform as a product manager. I defined the issues for the dev team into YouTrack and collected insights from the users. Finally, I created the knowledge base structure and content for the public GoodVision Knowledge Base.

my principles.

I’m a perfectionist. However, I’ve learnt that when building a MVP, it’s about the time. Therefore, I know how to switch a context quickly and manage to learn new things on the go if needed. People often say about me that I get the things done. Fast. I have no superpower. I only work systematically and follow my golden rule shortest task first.

I like to have my things clean and organized. Whether it’s my apartment, desk, desktop or my inbox. I am a protagonist of work hard, play hard. I will work on your last-minute task until midnight if it is crucial for you. However, to square up, I expect flexible working hours and environment.

freelance projects.

In every project, I start with a client’s expectations and specifications. If needed, I support the client with the initial setup, such as domain and web hosting. Afterwards, I create multiple prototypes/designs where the client chooses their favourite that I develop further. Finally, we execute a few iterations together until all sides are satisfied. Below is a selection of my freelance projects in the last five years, including mobile applications, website designs and graphic manuals.
