What I'm looking for

I’m looking for a backend-focused role where I can lead Java/Spring microservices on AWS, improve observability and performance, modernize legacy systems, and partner with product and support to resolve incidents fast.

I’m a senior software engineer with more than ten years of experience building and supporting scalable SaaS platforms with Java and cloud technologies. I focus on reliable backend services, RESTful APIs, production support, performance optimization, and enterprise modernization in Agile environments.

At EvolutionIQ, I lead enterprise SaaS platform services using Java, Spring Boot, RESTful APIs, Docker, Kubernetes, and AWS. I’ve strengthened production stability through advanced monitoring, logging, and structured operational excellence, while tackling critical incidents with deep root-cause analysis and log correlation to reduce recurring disruptions.

I also modernized legacy Java modules into maintainable Spring Boot microservices, improving deployment consistency, long-term scalability, and automated testing. I enhanced CI/CD pipelines with Jenkins, GitHub Actions, and AWS CodePipeline to automate builds, verification, and maintenance releases with higher operational confidence.

Earlier at Lukka and InRhythm, I delivered financial and enterprise backend services—building scalable microservices, designing efficient SQL/NoSQL data models, and implementing monitoring and metrics to improve issue detection and resolution. I bring a collaborative mindset—mentoring engineers, performing code and architecture reviews, and documenting operational procedures to keep teams aligned and systems dependable.
