Senior software engineer building low-latency backend systems for AI and real-time platforms.
United StatesWhat I'm looking for
I’m a Senior Software Engineer focused on building reliable, low-latency distributed systems that integrate complex data pipelines, machine learning models, and production-grade backend services. My work spans backend AI services, real-time systems, and ML infrastructure—supporting production AI services for clinical documentation and real-time delivery time prediction.
At Microsoft, I’ve led development of Azure OpenAI–based clinical documentation workflows (with clinician-in-the-loop review), designed prompt orchestration and RAG context assembly, and strengthened healthcare integration through FHIR/HL7 adapters with auditability and Responsible AI safeguards like PHI redaction and hallucination checks. Previously at Uber, I built and improved real-time ETD modeling and streaming feature pipelines using Kafka/Flink, deployed ML feature infrastructure for training-serving consistency, and supported experiments and monitoring to keep production models accurate across regions and changing demand.
Experience
Work history, roles, and key accomplishments
Worked on backend AI services for Microsoft Dragon Copilot, a clinical documentation platform integrating Azure OpenAI and Nuance speech/NLP in HIPAA-regulated environments. Led Azure OpenAI–based clinical documentation generation with prompt orchestration/RAG, improved clinical NLP and Nuance ASR post-processing, built FHIR/HL7 integration services, and implemented Responsible AI safety controls
Worked on Uber Eats’ core ETD system that predicts food delivery times in real time to power customer-facing ETAs, courier dispatch, and marketplace optimization. Built and improved multi-component delivery-time models, engineered geospatial feature pipelines (H3), implemented low-latency streaming feature pipelines with Kafka/Flink, and supported training-serving consistency and experimentation/d
Worked on Trello’s core collaboration product, a real-time task management platform for boards, lists, cards, and team collaboration. Built real-time collaboration features with Node.js and Socket.io, developed backend APIs using MongoDB, contributed to frontend migration from Backbone.js to React/Redux, and improved reliability of real-time synchronization by handling duplicate/out-of-order event
