Front-End Engineering
Product interfaces by Kacper Michalik—React, Next.js, and TypeScript with performance and motion in mind.
Kacper Michalik’s front-end engineering focuses on product interfaces that feel fast and considered: React and Next.js on TypeScript, with deliberate state management, animation, and rendering performance. He ships the user-facing layer of production products—not demos—and writes about real-world React UI patterns.
Focus
- Component architecture and typed UI systems in React and Next.js
- Rendering performance, interaction latency, and perceived speed
- Motion and micro-interactions that support product clarity, not noise
- Accessible, maintainable interfaces that survive long product lifecycles
Stack
- TypeScript
- React
- Next.js
- Gatsby
- styled-components
- Framer Motion / GSAP (where product motion needs it)
In production
- Screen Studio — co-developing the macOS product UI for automated, high-impact screen recording trusted by teams at GitHub, Vercel, and Y Combinator (#1 Product Hunt 2025).
- O-1A Hub — founder; product UI for an AI assistant with retrieval over U.S. O-1A visa guidance.
- Technical writing — “Modern React animation libraries” in SD Times, with production-oriented UI examples.

Kacper Michalik builds product UIs primarily with TypeScript, React, and Next.js (and Gatsby where static sites fit). He emphasizes typed components, rendering performance, and purposeful motion rather than decorative animation.
Which products show Kacper Michalik’s front-end work?
His front-end work appears in Screen Studio (macOS product co-development) and O-1A Hub. These are shipped products with real users, not portfolio mockups.
Does Kacper Michalik write about front-end engineering?
Yes. He has published on modern React animation libraries and engaging UIs in SD Times, grounded in patterns used in real product interfaces.
