Work Experience

Founding Engineer

LastCall

Aug 2024 - Present New York, NY
  • Built and shipped LastCall from zero to App Store as founding engineer — a TypeScript monorepo with an Express / Prisma / PostgreSQL (Supabase) API and a ~30-screen React Native (Expo) iOS app.
  • Owned the full scheduling domain end-to-end: shift management with overnight-time encoding, availability snapshots, a two-phase swap/cover approval workflow, and four-tier RevenueCat / Apple in-app-purchase billing on a 15+-model schema with role-based org auth.
  • Stood up the engineering foundation: GitHub Actions CI/CD (auto-deploy to Render + EAS build + App Store submission), Expo push, Sentry, and pre-10K-user performance work (local JWKS JWT verification, cursor pagination, DB indexing).

Forward Deployed AI Engineer

Tenex

Mar 2026 - Jun 2026 New York, NY
  • Delivered two production client projects end-to-end in three months, owning technical scoping, day-to-day client relationships, and final deployment as the forward-deployed engineer on each engagement
  • Designed and shipped an internal finance tool serving a 60-person client team, building the backend in Fastify (Node.js/TypeScript) and the frontend in Vite + React, and deploying the full stack on Google Cloud Platform
  • Led a Salesforce migration for a billion-dollar mineral company, re-architecting the client's existing infrastructure, data, and workflows into a newly provisioned Salesforce organization
  • Accelerated delivery timelines by integrating AI coding agents into the development workflow while holding output to production-grade standards

Full Stack Software Engineer

Greystone Medical Technologies

Feb 2026 - Mar 2026 San Diego, CA
