What I'm looking for

I seek a senior engineering role where I can design scalable cloud-native systems, lead technical initiatives, mentor engineers, and improve CI/CD and test-driven practices.

I am a Senior Full Stack Engineer with deep expertise in Java, React, and cloud-native architectures, focused on delivering scalable, maintainable systems using TDD and clean-code principles. I have built microservices, micro-frontends, and CI/CD pipelines while mentoring teams and improving developer productivity.

My achievements include designing a scalable email templating microservice, implementing micro-frontend solutions with React and Vite, and optimizing AWS-based deployment workflows. I bring strong full-stack experience across Spring, Node, Angular, and a variety of databases, and I aim to create reliable, performant software that meets business needs.
