I design and ship the invisible machinery — APIs, event pipelines and data layers that keep products fast under real-world load.

Manifesto

I write Java that stays fast at three in the morning, on the busiest day of the year, when nobody is watching. Boring infrastructure. Exciting uptime.

I'm Omeed Familie, a Java backend engineer with seven years of experience building high-throughput services for fintech, logistics and e-commerce platforms. My work lives behind the interface: domain-driven service design, event streaming with Kafka, well-indexed PostgreSQL schemas and the observability that lets a team sleep at night.


I care about clear contracts, honest benchmarks and code a new teammate can read on their first day. I've led migrations from monoliths to services, cut p99 latencies by an order of magnitude and mentored engineers into owning production with confidence.
