About me
👋 Hi there, I’m Radek!
I’m a software writer. I design, build, and maintain apps, and libraries to make apps. A particular interest of mine is making tools that help people be more productive.
I’m a proud generalist, always interested in broadening the spectrum of my craft. Since 2017, I’ve focused on building high-performance cross-platform apps. Lately, I’ve been helping startups grow from an idea to a successful business.
In my spare time, I work on machining, electronics, and infra projects at Warsaw Hackerspace, where I also serve as Secretary of the Board.
You’ll find me on the web on GitHub, Fediverse, and Twitter (but I try to stay away from social media these days).
Best way to contact me is via email.
Hire me
I’m occasionally available for short-term R&D projects and consulting. My rate ranges from $120/h to $250/h, depending on the type of project.
Some kinds of projects I’m particularly best suited for:
- WatermelonDB support, consulting, feature development
- Why me: I’m the author of WatermelonDB and helped many companies get the best out of the framework. Most recently, I developed Windows support for a French startup.
- React Native performance — consultation, optimization, code review
- Babel, ESLint plugins, JS codemod development
- Large-scale JavaScript (TypeScript, React, React Native) refactoring, architecture review, process improvement training
- Why me: I led the development of modern Nozbe application from its inception in 2017 through massive internal refactoring projects, ever-changing React Native, all the way to a large (200kLOC+) multi-platform (web, iOS, Android, macOS, Windows) application, all with a tiny development team of just 4 frontend developers.
If you’re interested in some of the above, or anything else, email me and let’s talk.
What I do now
- Presidential Title, revolutionizing real estate closing process in the US. I’m part of the founding team, and currently lead frontend engineering.
- Warsaw Hackerspace, a community (and a non-for-profit organization) of tinkerers, hackers, and software/hardware/mechanical engineers. I come here to (mostly) get away from computers and instead work on machining, mechanics, woodworking, electronics, even pandemic-time pro bono manufacturing. I serve as Secretary of the Board and also help maintain our software and physical infrasturcture.
Open source:
- 🍉 WatermelonDB. High-performance, reactive, lazy-loaded database & sync engine for React and React Native, featuring over ★10000 on GitHub.
- ZACS, a.k.a. Zero Abstraction Cost Styling, a small library that bridges the gap between DOM/CSS and React Native styling with zero performance penalty.

Past projects
- Nozbe, a project & task management app for teams and busy professionals. If you’re tired of forgetting things, organizing work through endless meetings, emails, phone calls, Slack, or JIRA, then Nozbe is definitely for you. I’ve been working with Nozbe since 2012, and most recently served the role of CTO, focusing on performance, infrastructure, dev process kaizen.
- Tadam. A simple Mac app that helps you maintain focus while working.
- Beam Valley. High quality engineering blueprint posters, laser-engraved onto wood. They would make your office look amazing, or make a great gift for a geek you fancy. It’s a fun side project to practice design and manufacturing. My posters:
- The Podcast. Weekly podcast I did with Michael from 2015 to 2021 (211 episodes) about productivity, business, books, and whatever else came to mind
- Productive Magazine. A monthly dose of productivity knowledge and inspiration.
