What I'm looking for

I’m looking for a Senior Full Stack / Tech Lead role where I can build secure, scalable Java/Spring microservices and React experiences on AWS, lead teams through architecture and mentorship, and ship improvements with strong DevSecOps and continuous learning.

I’m an innovative Senior Full Stack Developer and Tech Lead with 10+ years of experience, known for high productivity and efficient delivery. I specialize in Java, Spring Boot, Microservices, React, and AI-integrated platforms, and I’m recognized for designing scalable architectures and driving continuous improvement.

In my current role, I lead end-to-end architecture and development of an Authentication & Authorization platform using Java, Spring Boot, and Microservices. I’ve built AI-Agent integration pipelines for context-aware access decisions, architected graph-based identity and policy models in Neo4j, and implemented reactive microservices with Spring WebFlux for high-throughput security signal ingestion.

I also focus heavily on practical security outcomes, including JWT token issuance, validation, and rotation strategies, plus signed token verification for third-party integrations. Alongside this, I lead full-stack delivery with React JS for an admin dashboard that provides real-time visibility into authentication events and risk signals.

Earlier, I led cross-functional teams—such as a 19-engineer group at 7-Eleven Global Solutions—to deliver scalable systems aligned with business goals. Across roles, I’ve built and optimized REST APIs, improved scalability for growing traffic, supported agile execution, and mentored junior engineers through code reviews, clean architecture principles, and reactive programming patterns.
