What I'm looking for

I seek a cloud-native team role where I can lead architecture, deliver scalable web products, mentor engineers, and improve CI/CD and infrastructure efficiency.

I am a Senior Full Stack Engineer with 10+ years building high-performance, scalable web applications across industries. I focus on React, Next.js, TypeScript, Node.js, NestJS and AWS to deliver robust, maintainable solutions on tight deadlines.

At CareMax I engineered systems serving 100K+ monthly users, led a serverless migration to AWS Lambda, and improved deployment velocity and performance while mentoring junior engineers. I have a track record of reducing operational overhead, improving response times, and raising frontend Lighthouse scores.

My background spans backend microservices, cloud infrastructure-as-code with Terraform, CI/CD improvements, and cross-functional collaboration. I am eager to join a dynamic, cloud-native team where I can drive architecture decisions, mentor engineers, and deliver measurable product impact.
