My Story

I've been building since I was twelve. First graphic design, then an obsession with how the games I loved were actually made. Two questions, how it looks and how it works, that never came apart.

One became an eye for design. The other became a CS degree and a love for the part most people avoid: taking a hard problem apart until it gives.

Everything since is those same two instincts, aimed at bigger things.

Foundation

Computer Science, Western University. Dean's Honour List. Learned the thing I actually loved wasn't code. It was solving a real problem with it.

First product

Built a real estate platform and custom CRM from scratch. Frontend, architecture, all of it. The prototype raised six figures. First proof that what I build moves real money.

Scale, and a team

Senior frontend at 34MediaLabs. Shipped 4+ large applications end-to-end and led the team behind an early mobile app builder platform. Built an e-commerce frontend for 100,000+ users. Learned how systems break at scale, and how to lead people through it.

Around here the job stopped being “the frontend.” Clients never cared which layer a problem lived in. They cared that it got solved. So I stopped caring too, and followed problems wherever they went. Into the backend. Into mobile. Into whatever the answer actually required.

Enterprise

Open banking at CHECK24 in Munich. Then leading enterprise mobile at FieldFLEX, asset and facility management wired into IBM Maximo, TRIRIGA, and SAP, used by thousands of field technicians. Offline-first systems for people working where there's no signal. Mentored four junior developers. All four promoted inside eighteen months.

Whole platform, one engineer

Brought in as the sole frontend developer to modernize an environmental compliance platform for 1,000+ enterprise clients. Rebuilt the codebase for a 35% performance gain. Took test coverage from zero to 60%. Cut a core workflow from 12 minutes to 5 for 2,000+ daily users.

Owning a whole product alone became the default. Design, frontend, backend, deploy. So I started building complete products solo, a wedding-photo SaaS, an AI nutrition app on both app stores, a heavily animated studio site. Not prototypes. Live products, real users.

Leading the build

Back at FieldFLEX, leading frontend and defining how the team builds. This is where modern tooling comes in. I use AI to move faster and learn new ground quicker, but the value was never the AI. It's knowing what correct looks like before I ask for it. Seven years of shipping is what tells me when an answer is right, and when it's confidently wrong. That's why I set the standard instead of following one.

These days the work is fully distributed. Remote, async, decisions written down so anyone can follow them, products shipped end-to-end without hand-holding. The way good remote teams actually run.

I started as a kid who wanted to know how things were made. Still am. What changed is the size of what I can make, and how fast.
