What I'm looking for

I’m looking to build scalable, high-performance web experiences with real-time AI workflows—where I can improve engagement and reduce latency through strong frontend architecture, reusable components, and reliable CI/CD.

I’m a senior software engineer with 10+ years building scalable, high-performance web applications and AI-powered user experiences. I focus on frontend architecture, real-time AI workflows, and performance optimization that move engagement, latency, and developer efficiency.

At Airbnb, I architected AI-powered frontend experiences using React, Next.js, and LangChain workflows—improving user decision efficiency by 35%. I also led real-time AI dashboards with streaming model responses, reducing manual analysis time for internal teams.

I design reusable component systems and scalable frontend architecture so AI-enabled features can ship across multiple product surfaces faster. By optimizing rendering, API orchestration, and caching strategies, I reduced AI response latency by 25% and improved application responsiveness through Core Web Vitals work like code splitting and lazy hydration.

Across teams, I collaborate with ML, platform, and DevOps to deploy AI-enabled services on AWS Lambda and ECS with high-availability CI/CD. I’ve also mentored frontend engineers on scalable React architecture, performance optimization, and AI integration best practices.
