The story

not a résumé

The short version of a long obsession: making the web faster, and making it work for everyone — not as separate goals, but the same one.

2008 · The pixel years

It started one pixel at a time

I began where a lot of us did — turning Photoshop mock-ups into living websites at Ekko Media, pixel by pixel, browser by browser. It taught me the belief I still work from: the details aren’t the polish, they’re the product.

2012 · Out on my own

I learned to ship for real

I founded a studio, built a team of developers, designers and analysts, and carried projects from a napkin sketch to something a client would stake their name on. Running the whole lifecycle taught me what “done” actually means.

2016 · The turning point

Fast and inclusive, or it doesn’t ship

At the MIND Research Institute I rebuilt ST Math — a flagship learning platform used by millions of kids — from legacy Flash to modern HTML5. It got 0% faster, and I baked accessibility into the architecture instead of bolting it on, lifting mobile engagement 0%. That’s when the two halves of my work fused for good.

2022 · Leading at scale

The hard part is usually people

At Level Access I ran development teams across three continents, cutting delivery times up to 0% while raising the bar on WCAG compliance — leading code reviews, QA, and the client conversations where trust is actually won.

Now · Pixels & Code

Taking products the whole way

Today I design and build complete products end to end. The clearest proof is Airworthy — a live, multi-seller aircraft-parts marketplace with escrow payments, certification tracking, and a storefront in 0 languages — taken from an empty repo to real transactions.

The studio

idea → launch
Design-led software company

Founder & CEO — the software company I’ve built and led since 2012, now engineering and shipping original products end to end.

  • Full-stack web products — marketplaces, e-commerce, dashboards
  • Accessibility audits & remediation to WCAG 2.1 AA/AAA
  • Payments, internationalization & performance engineering

A company built to take products the whole way.

Most products die in the handoffs — between design and build, between “works” and “works for everyone,” between a prototype and something people can actually pay through. I’ve spent a career closing those gaps — and leading the teams that close them at scale, across three continents.

The result is software that loads fast, meets accessibility standards by default, and actually ships — backed by testing discipline earned over years of leading it for others.

Airworthy

Founder · design & engineering

A live marketplace for aircraft parts and whole aircraft. Multi-seller with Stripe escrow, 8130-3 / EASA Form 1 traceability, guest checkout, an AOG priority desk, and a full operator console — localized in eight languages with RTL.

ProblemAircraft parts still trade over email, PDFs and phone calls — slow, opaque and risky for six-figure inventory.

BuiltA multi-seller marketplace: Stripe escrow, 8130-3 / EASA Form 1 traceability, guest checkout, an AOG priority desk and a full operator console — in eight languages with RTL.

ResultAn empty repo to a live storefront taking real transactions and onboarding sellers.

ProblemA single seller wanted their own branded storefront — without a six-month build.

BuiltA turnkey, rebrandable commerce platform forked from the Airworthy engine — multi-item cart, promo codes, cross-reference part search and bulk CSV import/export.

What I stand for

non-negotiables

Four commitments behind every product Pixels & Code ships.

Accessibility

The web should work for everyone — no exceptions. I engineer to WCAG 2.1 AA/AAA as architecture, not an afterthought, so nobody gets left at the door.

Good ethics

No dark patterns, no data games. I build software I’ll happily put my own name on — honest, transparent, and unapologetically user-first.

Latest technology

Always on the frontier — React 19, Next.js, edge infrastructure, AI. Modern foundations keep products fast today and ready for whatever ships next.

Aviation

A lifelong pull toward flight. I build for the industry I love — Airworthy takes aircraft parts and whole aircraft to a global market, traceability built in.

Let’s build something
