Selected Work
Sentinel
Less downtime, faster recovery — root cause in seconds
When a production system goes down, every minute of downtime costs money. Sentinel cuts root-cause hunting from hours to seconds. Under the hood: a multi-agent AI system that diagnoses incidents like a senior on-call engineer — forming competing hypotheses, gathering evidence from telemetry and git history, eliminating causes, critiquing its own reasoning, and delivering a root cause, fix, and postmortem. Built on the Microsoft Agent Framework with Azure & GitHub MCP.

01A fast tool that saves dozens of clicks
A showcase of how I build tools: a clean, fast interface that answers a question in one search instead of clicking through five different sites. A toolkit for inspecting any IP address — geolocation, network and provider details, and more.
- Next.js
- TypeScript
- Docker
swiftnote
02A working product from idea to launch
A complete product I designed, built, and shipped end to end — from idea to deployment. Create and share self-destructing notes with ease — private by design, and gone the moment they've been read.

- TypeScript

03Removing the friction that kills conversions
A lightweight, inviting payment page. The same principle — remove friction — is what I use to get more of your visitors to buy or enquire. A simple alternative to GitHub Sponsors for accepting support from your community.

- 5+ years shipping software to production
I'm Marek — a full-stack developer with 5+ years building software from the first line of code to production. I help businesses turn ideas into fast, high-converting websites and apps — software that looks sharp, loads fast, and actually brings in customers.
I work across the whole stack, so your project is owned end to end by one person — no hand-offs between an agency and subcontractors. I build interfaces in Next.js and React, design APIs in Go and Node.js, and model data in PostgreSQL. You focus on your business; leave the tech to me.
Today I build software day to day for Ideacomp s.r.o. and lead engineering at Asuna Labs — so I know exactly how to take a product all the way to launch and keep it running. Alongside that I take on a limited number of select client projects, where you get my personal attention from start to finish. This isn't a side gig — it's work I genuinely care about.
