I'm a Senior Fullstack TypeScript Engineer with 5+ years shipping product features end-to-end on an enterprise education platform. I'm product-minded: I scope with Product Owners, instrument what I ship, and use metrics to decide what to build next.

At WSB Merito I own product surfaces end-to-end across 5 modules serving 60,000+ students yearly across 4 universities. I own the exporter — a multi-step dataloader — and the platform's most-used data table, including virtualization, data fetching and status handling: the frontend work users feel rather than see. I rewrote user-facing diagnostics so failures get reported clearly enough for QA to act on, and I'm currently consolidating PDF/DOCX generation so the logic lives where the data does, rather than scattered across features.

I also build the platforms other people work on: the Playwright E2E platform and SDK QA automation is written on, CI/CD deployment pipelines in GitLab and Docker with validation gates, an Nx monorepo (10 layered libraries, 2 apps), and the frontend architecture standards 8 developers work to. I currently co-lead AI enablement, an internal layer for CI/CD and Slack rolling out to ~30 devs, QA and analysts.

Before that I led frontend architecture across 6+ teams, rebuilt shared component patterns, and drove tooling migrations — Webpack to Vite, and a real-time data-table rebuild that took interaction from ~1s per click to 20ms. Outside work I build self-hosted projects: an Obsidian sync plugin and server, type-safe internal NPM packages, and a WebGPU shader/composition research engine.
