What I'm looking for

I seek senior technical roles where I can lead engineering teams, design scalable systems, drive architectural decisions, and build high‑throughput, reliable products in collaborative, fast‑paced environments.

I am a Senior Software Engineer with 8+ years of experience building full‑stack, cloud‑native systems for startups and enterprises, focusing on scalable trading infrastructure and high‑traffic user experiences.

At Robinhood, I engineered crypto trading products and core services using React/Next.js, Python, Node, and Go, improving API response times by 40%, reducing client bundle size by 25%, and supporting 10K+ concurrent orders/sec with lower latency.

I mentor engineers, design event‑driven microservices with Kafka/Redis, integrate AI fraud detection, and automate cloud deployments on AWS using Docker and Kubernetes to deliver reliable, high‑performance systems.
