Design and ship production-shaped systems end to end: retrieval and ML scoring services, cross-border commerce platforms, real-time data infrastructure and the polished front ends on top. Own architecture, delivery and code quality.

Led feature-rich web products on React/TypeScript over Node and PostgreSQL, plus Go and Rust services for the latency-sensitive paths. Introduced conventional commits, release branching and CI as the team scaled.

Built customer-facing storefronts, dashboards and internal tools across the JavaScript/PHP/Python stack; grew from feature branches into proper git-flow and annotated releases.

Shipped the first web apps — PHP/MySQL catalogues and vanilla-JS front ends — and learned the fundamentals of shipping, testing and version control in the open.
