Kacper Michalik

Software engineer, architect, and product builder with 8+ years of experience.

Started in design, evolved into full-stack engineering and cloud - now deeply focused on AI/ML.

Currently building Screen Studio - #1 Product Hunt 2025, trusted by teams at GitHub, Vercel, and YCombinator.

End-to-end ownership across the entire product lifecycle with focus on growth and impact.

Previously, I worked as a developer at a company that specialized in blockchain and cloud solutions.

I was also a core contributor to the open-source project, TryQuiet, which focuses on encrypted peer-to-peer team chat based on Tor without servers.
