What I'm looking for

I seek senior backend or platform roles building high-throughput, low-latency distributed systems with strong ownership, observability, and scalable cloud-native practices.

I am a senior backend engineer with over 10 years designing and operating low-latency, high-throughput distributed systems for fintech and cloud-native environments.

I specialize in Go and Python to build event-driven microservices that process hundreds of thousands to millions of transactions per day while maintaining strict consistency, sub-100ms latencies, and 99.99% availability.

I have led distributed teams of up to eight engineers, owned end-to-end system design, performance optimization, and production deployment on AWS EKS, emphasizing observability, fault tolerance, and cost efficiency.

My career highlights include architecting Kafka-based streaming pipelines, implementing gRPC inter-service communication, optimizing PostgreSQL performance, introducing Redis caching and rate limiting, and delivering 3–5× throughput improvements for global payment and blockchain transaction platforms.
