About

Data-heavy products, built end to end.

I'm a Senior Software Engineer at Strativ, building data-heavy web applications and e-commerce products with React, TypeScript, and Go.

Most recently I've been building a multi-tenant e-commerce ERP that handles 300K+ products on an event-driven backend. I work directly with clients to gather requirements, then own delivery through architecture, implementation, and release.

I coordinate the growth of a team of 4 engineers and work daily with Claude Code, Codex, and GitHub Copilot. Outside work I build open-source tools and write about Go, frontend performance, and AI.

Things I build in the open.

Locademy

An offline video course library for macOS, Windows, and Linux. Turns any folder of videos into modules, with progress tracking, auto-advance, and a built-in player. A Rust backend handles folder scanning and local persistence, and GitHub Actions builds installers for every release tag.

react-access-boundary-v2

An NPM package for permission-based UI and route protection in React. RouteGuard protects routes, components check single or multiple permissions with AND/OR logic, and an AccessProvider with a useAccessContext hook manages permissions globally. Suspense-compatible, with full TypeScript support.
