At Twinleaves (Pallet), I implemented catalog search backed by PostgreSQL and Elasticsearch across 1M+ products, sustaining 45K+ queries per minute at p99 latency under 18ms.
I expanded a shared cart and checkout system across POS, Restaurant, B2C, and B2B, and cut add-to-cart latency by 94%. I also developed chat-based AI agents for catalog management and website creation, reducing product onboarding and website setup time.
I built Java and Spring Boot microservices for retail and restaurant platforms, including delivery serviceability with PostgreSQL and PostGIS, and set up the platform’s first GCP environment and deployment pipelines.
I launched JobBeeper, a job-alert platform serving 2K+ active users, and built its job-matching and notification pipelines. At Twinleaves, I also led backend engineers and developed shared libraries for access control, rate limiting, and AI usage tracking.
