What I'm looking for

I am seeking a senior engineering role building scalable backend systems and AI integrations, in collaborative teams that value reliability, mentorship, and measurable product impact.

I am a Staff Software Engineer with deep experience building scalable backend systems, AI-driven features, and observability for enterprise products. I design and implement microservices, data ingestion pipelines, and AI assistants that move large volumes of documents and automate workflows.

At Glean, I led tenant-isolated data ingestion and RAG-based AI assistant efforts, reducing repetitive knowledge lookup work by 40% and lowering system latency by 35% through service-level Golang microservices. I also improved MTTR by 40% via Datadog instrumentation and Kafka-based observability.

Previously at Chiron Health I built a HIPAA-compliant telehealth platform deployed on AWS, implemented WebRTC video visits, payment flows, and secure APIs, and drove growth in provider onboarding and visit volume. I have a proven record of improving throughput, reducing manual work, and scaling platforms to meet increased concurrent load.

I enjoy mentoring engineers, collaborating with product and design teams, and delivering reliable, performant systems using modern cloud, AI, and testing practices. I seek opportunities where I can architect robust systems, integrate AI responsibly, and help teams ship excellent products.
