Hi, I'm Miko 👋
I build polished mobile and web products — currently in fintech at IG Group. Based in Warsaw, comfortable in international teams, and currently building Lismova, a pixel-art app for learning Belarusian.
I'm a Senior React Native Developer who enjoys taking products from an idea through to something polished and shipped. I care about smooth interactions, maintainable code, and the planning conversations that make a project succeed.
Having lived in 7 different countries across Europe, Asia and the Middle East, I'm comfortable in international teams and well versed in cultural differences.
Helped build and launch IG Invest, a zero-commission stock & ETF investing app now live in the UK, using TypeScript, Redux Toolkit and Reanimated. Worked closely with product, design and stakeholders on planning and delivery, and acted as squad lead for a small mobile squad. Promoted to Senior in December 2025.
Built frontend code across multiple client projects, supported clients with architectural knowledge, and liaised with product, design and development teams to ensure the quality of deliverables.
Spearheaded the development of an internal testing app, written in React Native, used to test in-app purchases on Android and iOS.
Learn Belarusian — pixel-art lessons & flashcards
A Duolingo-style app for learning Belarusian — one of Europe's most underserved languages, which the big apps simply don't teach. The name blends ліс (fox) and мова (language), with a pixel-art fox as the mascot. Built in React Native with a hand-styled retro aesthetic: bite-sized lessons, a swipeable flashcard deck, and full verb conjugations — all fully offline, no account, no ads.
I'm building it solo, with content verified by a native speaker. The pixel art is rendered with React Native Skia for crisp upscaling on high-DPI screens.
I'm always happy to talk about new opportunities and projects.
