What I'm looking for

I seek senior engineering roles building cloud-native, microservices-based systems with strong DevSecOps practices, mentorship opportunities, and measurable impact.

I am a Senior Full Stack Engineer with 10+ years building enterprise-scale, cloud-native systems across healthcare, airlines, automotive, and finance. I specialize in Java (Spring Boot), Node.js/NestJS, React, and scalable AWS architectures.

I've modernized monoliths into secure microservices, designed Kafka/Redis event pipelines for real-time processing, and led engineering best practices in TDD and DevSecOps, improving uptime and reducing latency and costs.

I partner with product, security, and data teams to deliver compliant, high-throughput services used by millions, mentor engineers, and drive architecture and CI/CD improvements to increase reliability and developer velocity.
