What I bring to the team.

01 / 04

Payment architecture

Payment flows where correctness, idempotency and auditability come first — and the integration still stays simple for the team.

02 / 04

Full-stack delivery

From React + TypeScript interfaces to the services behind them — one engineer who can own a feature end to end.

03 / 04

Backend & APIs

Node, Express, Laravel and .NET services with clean contracts, sensible caching in Redis and databases that stay fast.

app.post("/api/v1/orders", validate, handler)
04 / 04

Technical leadership

Planning, architecture reviews, code reviews and hands-on debugging — keeping teams shipping without lowering the bar.

// plan → review → ship → repeat
// 04. stack

Everything orbits the core.
