Software engineer · Prague

Economist by training. Engineer by choice.

I studied financial economics in Toronto, then software engineering in Prague. Now I build iOS and Android apps, with AI doing most of the typing and me deciding what's worth building and how it should work.

About me

Economics was the plan. Then I got curious about the code behind the tools I was using—and wanted to learn to build them myself. These days, I mostly build mobile apps. My economics background still shapes how I work: untangling complex problems for clients, figuring out what’s worth building, and seeing it through.

How I think

Code is cheap. Thinking isn't.

With AI writing more and more of it, the valuable work is everything around the code: owning the product, being a real partner to the client and getting the architecture right.

I do miss writing code sometimes, though.

Every feature is an investment.

I look at a feature the way I learned to look at an investment: what it costs, who it's for and what it returns. Sometimes the best engineering decision is not to build it at all.

Even if it means I don't get paid to build it.

My niche isn't my limit.

I understand how software is built, so I can build in languages and frameworks I haven’t used before. AI helps fill in the syntax, and I learn the rest as I go.

This website? The first one I’ve ever built.

What I build

My work, in practice.

Mobile apps

I build native iOS and Android apps, sharing as much logic as possible with Kotlin Multiplatform. I help shape features, keep the architecture clean, and see the work through testing and release.

  • iOS
  • Android
  • Kotlin Multiplatform
  • Swift / SwiftUI / UIKit
  • Kotlin / Compose
  • App architecture
  • Testing
  • CI/CD

AI development workflows

I build tools that help AI agents work with a codebase and check their results. That includes reusable rules and skills, automated app testing, and build workflows that support working on several tasks at once.

  • Claude Code
  • Codex
  • MCP servers
  • Rules & skills
  • Agentic Review & QA
  • Parallel workflows
  • CI/CD

I'll tell you if it's worth building. Then I'll build it.

Whether it's a role, a product you want to build, or just a conversation about KMP or AI workflows, I'd love to hear from you.
