United StatesWhat I'm looking for
I am a Senior Software Engineer with over a decade of experience designing scalable backend systems, cloud-native architectures, and AI-powered products that serve global user bases.
At Airbnb I led AI-powered search and support systems, reduced IVR error rates from 33% to 10%, and built ML data engineering platforms processing 1M+ events/sec for personalization and recommendation use cases.
I have decomposed legacy monoliths into microservices, improved CI and deployment pipelines, optimized cloud infrastructure on AWS, and driven frontend migrations to React and SSR to improve load times and user engagement.
I mentor engineers, prioritize data-driven decision-making, and focus on reliable, scalable systems that improve user experience, accessibility, and business metrics.
