About
Backend engineer who built and evolved ConGreG8 end-to-end: a stateless Node/Express REST API on MongoDB for fast, location-based church discovery. Demonstrates strong performance and operability discipline (instrumentation, p95 latency, slow-query analysis) with a reported ~30% response-time improvement, plus security depth via JWT/OAuth and Supabase-style row-level security. Experienced in safe refactors with contract preservation, dual-read validation, and incremental rollouts.

Key Strengths
- Designed and built a full-stack backend (Node/Express + MongoDB) for location-based discovery product
- Performance instrumentation and optimization using average/p95 latency and MongoDB query analysis; reduced API response times ~30%
- Stateless API design with token-based auth and minimal per-request user context fetching
- Contract-first API approach with strict schema validation and consistent error models (FastAPI/Pydantic)
- Incremental refactor/migration execution with frozen external contracts, dual-read validation, and route-by-route rollout
- Defense-in-depth security mindset: JWT/OAuth, scoped permissions, and database-enforced row-level security (Supabase RLS)
- Proactively identified data integrity edge case (orphaned reviews) and implemented cascading deletion with test coverage
