Great design, made simple.

I'm Vadim, a designer and builder based in Prague. I work at Efsy COFL and run Kefir Software Company - designing and shipping interfaces that look considered and hold up in production.

Vadim Filatov is a Prague-based UI/UX engineer and visual designer bridging the gap between clean aesthetics and frontend code. With 3 years of experience in marketing and branding, he launches high-converting websites and human-centric digital products for forward-thinking small businesses and independent founders.

By combining structured visual languages with production-ready React and Next.js code, he delivers fast, intuitive interfaces. Every system is optimized for performance and completely free from the typical disconnect between design and development.

Working directly with founders and product teams, Vadim brings a holistic, business-minded lens to every project - uniting strategy, UI/UX design, and front-end execution. No agency overhead, no account managers, and no clumsy handoffs.

One clear point of contact, structured design, and products built to scale.

01 Design that ships

Layouts leave Figma as production-ready React and Next.js. No handoff gap, no lost spacing, no 'the developer will figure it out'.

02 Direct collaboration

You talk to the person doing the work. Feedback stays fast, decisions stay documented, and the project never waits on an account manager.

03 Systems over one-offs

Visual language, components, and code are built to scale. The first page should still make sense when the tenth one arrives.
