Building Software That Lasts

I've spent my career in environments where mistakes are expensive, systems live for years, and clarity matters more than hype.

The Journey

From enterprise foundations to founder

The Foundation
2010

Enterprise systems at scale

Started in large enterprise systems, working on production software before touching greenfield projects. This foundation shaped a pragmatic approach with respect for legacy, performance, and real users.

Healthcare & Growth
2015

US healthcare, stepping into senior roles

Moved into regulated healthcare systems in the US, stepping up from writing code to owning features, mentoring developers, and leading frontend migrations.

Legacy Mastery
2018

UK EdTech, owning complex systems

Joined teams at moments of transition - legacy systems, rapid growth, missing structure - and helped stabilize, modernize, and move them forward.

Real-time Excellence
2019

Gaming, performance-critical systems

Built real-time gaming products where milliseconds matter, working closely with world-class professionals and delivering platforms tested at the highest level.

Founding Stomačko
2021

Company creation, product + client work

Founded Stomačko to combine client work with products I care about — software that touches everyday life, health, and real-world problems.

Today
2026

Focused and independent

Architecture, engineering, and technical leadership on complex web applications — stepping in when projects need depth over headcount.

My Approach

Principles that guide every project

Pragmatic Engineering

Respect for legacy, performance, and real users. Solutions grounded in what actually works, not what's trending.

Direct Accountability

Every decision has a name behind it. I make architectural calls meant to hold up for years — no layers between me and the outcome.

Clarity Over Hype

Reliable, understandable systems. No unnecessary complexity, no chasing trends — just solutions that work.

Founded 2021

The Stomačko Story

In parallel with client work, I've always built products of my own. Some commercial, some experimental, some purely driven by purpose. That instinct eventually led to the founding of Stomačko.

Stomačko began as a food optimization platform focused on affordability and simplicity, but it also became a natural umbrella for projects where software meets everyday life, health, and real-world constraints.

Today, I deliberately keep Stomačko small — collaborating with trusted partners when needed, because I believe accountability and clear communication matter more than headcount.

Building things that matter beyond business has always been part of what Stomačko does. It started with 'pink recipes' on the Stomačko food platform — meal ideas for women going through breast cancer treatment, created with oncology patient advocates and recognized as a top 3 initiative at a pan-European conference in 2023. That spirit carried forward into OnkoVodic, a dedicated patient navigation platform now live at rak-dojke.com. When software can make a real difference in someone's life, that's the kind of work worth doing.

Software should earn its place by being reliable, understandable, and genuinely useful.
A Personal Note

Outside of work, I play chess competitively — it's shaped how I think about trade-offs and long-term strategy. The goal is always the same: leave things better than I found them.
