What I'm looking for

I am seeking senior engineering roles where I can design scalable systems, mentor teams, and deliver high‑impact products in collaborative, fast‑paced environments.

I am a Senior Software Engineer with 10+ years of experience building scalable full‑stack systems at startups and large enterprises. I have led Agile teams, mentored engineers, and driven technical solutions across payments, realtime collaboration, and internal productivity tools.

At Stripe I scaled core payment infrastructure, built high‑performance APIs in Ruby, Scala, and Go, implemented GraphQL with Apollo, and created interactive D3 visualizations while reducing API response times and false positives in fraud detection. I also architected microservices on AWS and improved observability with Datadog and Prometheus.

Previously at Airtable I developed dynamic UIs, realtime collaboration features, and backend services, improving latency and data consistency while leveraging Node.js, Kafka, Redis, and serverless AWS components. I am committed to shipping reliable, performant software and fostering strong cross‑functional collaboration.
