Projects

A short list of production-minded systems — retrieval that cites its sources and knows when to abstain, and event-driven backends built to stay correct under retries and redelivery.

GroundedDocs

2026

Private document Q&A that answers only with a faithful citation from the user's files — and abstains when it can't.

FastAPI · PostgreSQL · pgvector · LangGraph · OpenAI

Kafka Order System

Order and notification microservices on Kafka — Avro + Schema Registry, idempotent writes, retries, a dead-letter queue, and Prometheus-backed observability.
