What I'm looking for

I’m seeking a senior engineering role where I can design and ship AI-integrated web platforms, lead technical teams, improve performance and reliability, and scale cloud-native systems in a collaborative, privacy-conscious environment.

I am a versatile senior full-stack engineer with eight years building scalable, AI-integrated web platforms across healthcare, finance, and retail.

At Walmart I led development of AI-driven retail automation that improved customer service resolution times by 52% and re-architected backend services to 99.98% deployment reliability; at Intellectyx and Newegg I migrated legacy dashboards, built serverless backends handling 900K+ monthly requests, and delivered eCommerce features supporting 1M+ monthly sessions.

I work across React, Next.js, Node.js, NestJS, TypeScript, AWS and Azure, Docker, and OpenAI APIs, focusing on performance optimizations, CI/CD automation, and robust testing practices to reduce latency and production bugs.

I enjoy mentoring engineers, establishing scalable code review and documentation processes, and collaborating with cross-functional teams to deploy privacy-compliant LLM tooling that drives measurable business impact.
