Software engineer building scalable, cloud-native, event-driven distributed systems.
United StatesWhat I'm looking for
I am a software engineer with 5+ years building scalable, reliable, event-driven distributed systems and cloud-native applications. I have architected production-grade platforms — from LLM inference stacks to high-throughput messaging and real-time feature stores — delivering measurable uptime, latency, and cost improvements.
My work spans designing microservices, stream processing, and resilient infrastructure on AWS, Azure, and Kubernetes, with a strong focus on performance optimization, exactly-once semantics, and operational excellence. I mentor junior engineers, drive DevOps practices, and prioritize observability and automation to reduce MTTR and operational incidents.
