I build scalable, low-latency backend and distributed systems for commerce, trading, and infrastructure.
United StatesWhat I'm looking for
At Amazon, I architect and deliver distributed backend services, APIs, persistent data systems, and customer-facing experiences for grocery subscription and consumer-commerce workflows. I improve high-volume production services through asynchronous processing, caching, idempotent workflows, automated recovery, and observability.
Previously, I built low-latency electronic trading systems at Bank of America Merrill Lynch and an equity algorithmic trading startup using Java and C++, covering real-time order processing, market data, execution, replay, backtesting, and quantitative research. My work also includes high-performance C/C++ networking and telemetry software at Cisco, with end-to-end ownership from architecture and API design through production reliability.
