A small set of projects that demonstrate how I think about performance, resilience, and operating systems in production.

CDC Stream

Database time machine — captures every change from Postgres and lets you replay history safely.

Change Data Capture system that streams PostgreSQL WAL changes into Redis Streams for low-latency consumers and Kafka for durable archival. Supports controlled replay of historical events via gRPC and a Django admin dashboard, so you can debug, audit, or rebuild downstream state without touching production traffic.
