Average engineers ship features. Trusted engineers protect the system.

I architect and lead high-performance, real-time frontends in iGaming — hands-on with React and TypeScript, and the person teams rely on to set direction, raise the bar, and ship.

Ten years in real-money gaming: owning frontend architecture end to end, setting standards teams actually follow, and staying hands-on in the codebase so the direction I set holds up under review.

What I own

Technical direction

Architecture, module boundaries, and the rendering foundations everything else gets built on.

Standards

Review culture, shared patterns, and performance and accessibility budgets held as defaults, not asks.

The team

Mentoring, developer experience, and tooling as a force multiplier — so delivery never depends on heroes.

How I lead

Teams ship, not heroes

Mentoring, healthy developer experience, and tooling as a force multiplier for the whole team.

Hands-on leadership

Still in the codebase — reviews and the hard problems — so I lead with credibility, not from a distance.

Decisions in the open

Lightweight RFCs and ADRs, pragmatism over dogma, and choosing boring technology where it counts.

Architecture over frameworks

Component-driven design, clear module boundaries, and design systems that scale with the team — not just the app.

Performance is a feature

Performance budgets, measured rendering, and smooth real-time UX built in from the start, not bolted on.

Quality by construction

Testable UI, accessibility as a baseline, and a code-review culture that raises everyone's bar.
