Actions
With 11+ years of experience at Meta, Amazon, Block, and MongoDB, I specialize in building distributed microservices for 10M–100M+ Daily Active Users. At Block, I led the redesign of Cash App's peer-to-peer payment engine, supporting 25M weekly senders and driving $109M in Q1 2024 revenue, while building a 10K event/sec platform that prevented $220M in fraud losses via ML risk signals. My work at Meta involved optimizing replica synchronization for ZippyDB, their largest distributed key-value store, and at Amazon, I led a cross-functional team to build Alexa News microservices, resulting in a 32% engagement lift and $4.5M in Ads revenue. I am currently engineering LLM-powered code generation at MongoDB to automate the modernization of legacy Oracle PL/SQL to Java and MongoDB for global financial institutions. I am also a key contributor in an open source library for model distillation (https://github.com/horus-ai-labs/DistillFlow/) which has gotten over 150 stars on Github.
