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 as an umbrella for both client work and product initiatives. A company created to house projects where software meets everyday life, health, and real-world constraints.

Today
2025

Premium, senior-led, focused

Operating as a small, senior-led company. Working directly with clients to build premium web applications, lead teams, and step in when projects need experience more than headcount.

How I Work

Principles that guide every project

Pragmatic Engineering

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

Ownership Mindset

Leading teams, making architectural decisions meant to hold up years down the line. Accountability over process.

Clarity Over Hype

Building things that are reliable and understandable. Clear communication and technical judgment matter more than scale.

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, it operates as a small, senior-led company. I deliberately keep it small, collaborating with trusted partners when needed, because I believe accountability, clear communication, and technical judgment matter more than scale.

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

Outside of work, I'm a competitive chess player, which has quietly influenced how I think about systems, trade-offs, and long-term strategy. I care deeply about mentorship, product quality, and building technology that respects both users and the people maintaining it. The goal is always the same - leave systems better than I found them.
