I build indie apps, give conference talks, and tinker with AI tools.
One-person studio shipping mobile apps and sharing what I learn on stage. This is the home for everything I make — apps you can install today, talks I've given (or want to give), and the AI skills and agents I'm building along the way.
Software I ship under the NowakApps name.
Found one of my apps in the store? Here's everything else I've built — same care, same studio.
A decade of speaking — refactoring, Kotlin, Android internals, and AI.
Looking for a speaker? Here's a sample of what I've talked about, from production refactors to Kotlin Flow internals to introducing AI agents to engineering teams.
Reusable Copilot skills and custom agents.
Small, focused AI tools — skills and agents — that I've built or am building. Each one links to its source on GitHub so you can install and remix it.
Hi, I'm Mikołaj.
Senior Android engineer by day, indie developer by evenings and weekends. I've spent years on long-running production codebases — refactoring legacy, shipping features, and trying not to ship regressions — and I bring that same discipline to my own apps. I also speak at conferences and meetups about Kotlin, Android, refactoring, and now AI agents in real engineering workflows.
