Full-Stack Engineer · TypeScript · Go · Distributed systems · Building CareerOS
Full-stack engineer with a learn-by-doing mindset, strongest on the frontend and just as comfortable deep in distributed backends and infra. I've shipped fintech wallets handling $1M/month, products that raised $100K in VC, and platforms used by hundreds of enterprise customers.

- 🚀 Building CareerOS, a career-services platform for universities

A Turborepo monorepo of 18+ services — and I work across most of it:
- 🗓️ Built a complex event-management system (multi-timezone, attendance, speakers, Google Maps, email flows) for employers and universities
- 💼 Built the employer hiring product from scratch — job posting, company profiles, talent search — landing 300+ customers in under a year
- 🧩 Created a shared component library from zero to unify visuals and logic across the student, advisor and employer apps
- ⚙️ Stack I touch daily: Node + tRPC + Drizzle APIs, Go (Gin) core services, React SPAs, plus Python AI agents (LangGraph + Gemini) — all on GCP Cloud Run + Terraform with auto-versioned CI/CD
