What I'm looking for

I seek engineering roles combining system design and AI integration, collaborative Agile teams, mentorship opportunities, and measurable impact on customer metrics.

I am a Staff Software Engineer with deep experience designing scalable, AI-enabled ecommerce and telehealth platforms. I build microservices backends in Golang and Python, and craft high-performance frontends with Next.js and TypeScript, focusing on measurable business outcomes.

At Amazon I led development of an AI-powered ecommerce platform, authored recommendation systems using LLMs, and improved conversion and engagement through performance optimizations and robust CI/CD. Previously, I helped migrate and modernize telehealth systems to cloud-native architectures, implemented WebRTC video consultations, and ensured HIPAA-compliant data handling.

I thrive in Agile teams, mentor engineers, and apply best practices across testing, observability, and deployment to deliver reliable products at scale. I seek roles that let me combine system design, ML/AI integration, and developer velocity to drive impactful customer experiences.
