==
I’m a full-stack software engineer and technical lead with 5+ years building production systems across consumer apps, geospatial platforms, and AI-powered search. I’m looking for full-time roles in full-stack engineering, platform engineering, geospatial/AI infrastructure, or product-minded engineering.
Past work:
- Architected a 3.55M+ POI geospatial platform with sub-20ms query latency at 1M+ requests/month using Overture Maps, OpenStreetMap, H3, PostGIS, and pgvector.
- Built D-GIX, a 3-layer semantic search system that lifted Recall@10 from 0.20 to 0.97 using Sentence-Transformers embeddings, temporal state machines, and HNSW indexing.
- Cut infrastructure costs 98.7% and achieved a 24x indexing speedup by migrating to H3 hexagonal tiling with PostGIS, query optimization, and connection pooling.
- Deployed and scaled the unified PostGIS/pgvector architecture on AWS EC2, sustaining 4,414 concurrent requests with 0% failure rate.
- Led Landmarks, a gamified location-based app, from concept to public beta in 4 months with zero critical defects while coordinating 12 engineers across React Native and Node.js.
- Migrated a Fortune 500 retail client’s React Native app from untyped JavaScript to strict TypeScript, converting 150K+ lines with zero breaking changes.
- Engineered Java Spring Boot microservices processing 50K+ daily transactions at 99.9% uptime, plus a GraphQL API layer that cut payload over-fetching 40%.
- Built a real-time WebSocket + Redis pub/sub notification system that cut alert latency from minutes to under 2 seconds.
