What I'm looking for

I am seeking a leadership role where I can drive cloud-native platform architecture, mentor engineers, improve reliability, and deliver scalable microservices while aligning technical solutions with business strategy.

I am a Technical Lead and Senior Software Engineer with 9+ years building highly scalable, cloud-based systems across aviation, healthcare, and insurance. I specialize in Java and Spring Boot, monolith-to-microservices migrations, and optimizing cloud platforms for performance and cost.

I have led and mentored teams of up to 15 engineers, owned backend and platform architecture, and driven technical roadmaps aligned with enterprise architecture. I take responsibility for production reliability, on-call rotation, and incident handling while improving CI/CD, testing, and code quality standards.

My practical experience includes Azure and AWS cloud environments, containerization with Docker, infrastructure as code with Terraform, and observability stacks like ELK and Grafana. I focus on delivering secure APIs, identity/auth components, and long-term platform strategy that balances stakeholder needs and budget constraints.
