Hi, I'm Matko.

Building and running engineering teams. Hiring, mentoring, workshop facilitation, technical strategy across markets. Active participation in sales: pitches and proposals.

Caring about what the user actually experiences and how useful the product is in practice. Interfaces that are simple, intuitive, accessible, and verified in real use, with functionality picked for the value it brings rather than the surface area it adds.

Structuring a system so it stays understandable and cheap to change as it grows. System design from C4 diagrams down to running code, API contracts, integrations, decision records, vendor analysis, context maps, and Event Storming for shared understanding across business and engineering.

The working habits that let a team ship frequently and safely, and change direction without drama. Domain-Driven Design, Test-Driven Development, continuous deployment with multiple releases per day, feature flags, DORA metrics, security-by-design, experimentation.

Native Android (Kotlin, Jetpack Compose, BLE, on-device ML), backend (Kotlin, Java, PHP, Python, JS/TS), web (JS/TS, React), cloud (AWS, Hetzner), CI/CD pipelines, Postgres and MySQL.

Practical use of Claude Code, ChatGPT, Gemini, and similar tools across coding, knowledge work, and reporting, with an honest take on what works and what doesn't.
