What I'm looking for

I’m looking to own backend architecture end to end for data-heavy products—shipping reliable, low-latency services and scaling systems with AWS, modern Python/TypeScript, and performance-first engineering.

I’m a backend developer who owned systems end to end for a production DeFi platform, spanning a yield analytics engine covering 50+ protocols. I built a CoW Protocol solver to settle user orders within a 7-second block window, with simulation and execution engines that validate solvability and maximize profitability.

I also engineered a computation and update pipeline that unifies yield/liquidity data across protocols, reconciles emissions and accounting differences, and stays resilient to flaky RPC providers. Using async Python (FastAPI) with caching and efficient batching (multicall), I served 3,000+ concurrent requests at sub-15ms p99 on cached reads, while keeping tail latency stable under load.
