## About

I build and scale \*\*𝗱𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱 𝘀𝘆𝘀𝘁𝗲𝗺𝘀\*\* — from \*\*𝗽𝗲𝘁𝗮𝗯𝘆𝘁𝗲\-𝘀𝗰𝗮𝗹𝗲 𝗱𝗮𝘁𝗮 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀\*\* to \*\*𝗵𝗶𝗴𝗵\-𝘁𝗵𝗿𝗼𝘂𝗴𝗵𝗽𝘂𝘁 𝗯𝗮𝗰𝗸𝗲𝗻𝗱 𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀 \(\~1\.8𝗠 𝗤𝗣𝗦\)\*\*\. Over the past 12 years, I’ve worked across \*\*𝗯𝗮𝗰𝗸𝗲𝗻𝗱 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲\*\*, \*\*𝗿𝗲𝗮𝗹\-𝘁𝗶𝗺𝗲 𝗱𝗮𝘁𝗮 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴\*\*, and \*\*𝗱𝗮𝘁𝗮 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀\*\*, building systems that power critical business workflows\. My experience includes \*\*𝗲𝘃𝗲𝗻𝘁\-𝗱𝗿𝗶𝘃𝗲𝗻 𝘀𝘆𝘀𝘁𝗲𝗺𝘀\*\*, \*\*𝗺𝗶𝗰𝗿𝗼𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀\*\*, and \*\*𝘁𝗵𝗼𝘂𝘀𝗮𝗻𝗱𝘀 𝗼𝗳 𝗯𝗮𝘁𝗰𝗵 & 𝗿𝗲𝗮𝗹\-𝘁𝗶𝗺𝗲 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀\*\*\. At Uber, I’ve led high\-impact initiatives across \*\*uMetric \(metrics platform\)\*\* and \*\*Marketplace Config \(Forge\)\*\*, improving \*\*𝗿𝗲𝗹𝗶𝗮𝗯𝗶𝗹𝗶𝘁𝘆\*\*, enabling \*\*𝘀𝗮𝗳𝗲 𝗲𝘅𝗽𝗲𝗿𝗶𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻\*\*, and driving \*\*𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝗮𝗱𝗼𝗽𝘁𝗶𝗼𝗻\*\*\. I owned and delivered org\-wide efforts like \*\*𝗖𝘂𝗯𝗲 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻\*\*, reducing onboarding time from weeks to hours and enabling self\-serve usage at scale\. More recently, I built \*\*“𝗣𝗹𝗮𝗶𝗻 𝗧𝗮𝗹𝗸” — 𝗮𝗻 𝗔𝗜\-𝗱𝗿𝗶𝘃𝗲𝗻 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺\*\*, leveraging \*\*𝗟𝗟𝗠𝘀 \(𝗖𝗹𝗮𝘂𝗱𝗲 𝗦𝗼𝗻𝗻𝗲𝘁\)\*\* to convert natural language into executable workflows\. This involved designing \*\*𝗮𝗴𝗲𝗻𝘁𝗶𝗰 𝘀𝘆𝘀𝘁𝗲𝗺𝘀\*\*, implementing \*\*𝗥𝗲𝗔𝗰𝘁 𝗽𝗮𝘁𝘁𝗲𝗿𝗻𝘀\*\*, and integrating \*\*𝗯𝗿𝗼𝘄𝘀𝗲𝗿 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 \(𝗣𝗹𝗮𝘆𝘄𝗿𝗶𝗴𝗵𝘁\)\*\* for real time execution\. Using LangChain , langGraph , evals etc\. I enjoy solving \*\*𝗮𝗺𝗯𝗶𝗴𝘂𝗼𝘂𝘀 𝗽𝗿𝗼𝗯𝗹𝗲𝗺𝘀\*\*, leading \*\*𝟬→𝟭 𝗶𝗻𝗶𝘁𝗶𝗮𝘁𝗶𝘃𝗲𝘀\*\*, and influencing \*\*𝘁𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗱𝗶𝗿𝗲𝗰𝘁𝗶𝗼𝗻\*\* across teams\. I’ve mentored engineers and driven best practices across \*\*𝗼𝗯𝘀𝗲𝗿𝘃𝗮𝗯𝗶𝗹𝗶𝘁𝘆\*\*, \*\*𝗼𝗻\-𝗰𝗮𝗹𝗹\*\*, and \*\*𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗿𝗲𝗹𝗶𝗮𝗯𝗶𝗹𝗶𝘁𝘆\*\*\. Tech: Go, Java, Python \| Kafka, gRPC, Cadence \| AWS, GCP Services \| Redis, Cassandra, MySQL \| Hive, Presto, Pinot, Spark \| LLM / GenAI systems If you're working on \*\*𝗹𝗮𝗿𝗴𝗲\-𝘀𝗰𝗮𝗹𝗲 𝘀𝘆𝘀𝘁𝗲𝗺𝘀\*\* or \*\*𝗔𝗜\-𝗱𝗿𝗶𝘃𝗲𝗻 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀\*\*, I’d love to connect\.\.
