What I'm looking for

I'm looking to build reliable, scalable, high-performance products and backend systems, especially in remote teams where I can improve architecture, operational maturity, and developer onboarding.

I've rebuilt GitBook's search system on Turbopuffer, Redis, and RPC for documentation sites serving millions of page views daily, while improving relevance, performance, and sustaining costs. I also led a no-downtime migration of tens of millions of Firestore records to PlanetScale, improving query latency by approximately 5x.

At Portchain, I built dozens of event-driven integrations across Kafka, REST, SFTP, and webhooks for maritime shipping operations. I migrated a legacy PostgreSQL database without downtime, established observability and incident-management systems, and mentored engineers working in a complex distributed domain.

Earlier, I built satellite ground-segment and image-processing software for TURKSAT-6A, IMECE, and GOKTURK-2, including a CPU-GPU codec that delivered a 20x speed-up. I bring twelve years of product engineering experience, with a focus on backend reliability, scalability, and performance.
