United StatesWhat I'm looking for
I am a Staff Software Engineer with 11+ years building large-scale distributed systems at Amazon and Shopify, focused on scalable architectures, performance, and production reliability. I lead cross-functional teams, design event-driven microservices, and drive technical roadmaps while mentoring engineers to raise delivery standards.
My work includes architecting telehealth platforms supporting thousands of concurrent sessions, modernizing deployment pipelines with Kubernetes and EKS, and integrating AI/ML features for predictive insights. I prioritize measurable improvements—reducing latency, increasing throughput, and improving release cadence—while ensuring secure, highly available systems.
