Summary

I’m a problem solver, not just a coder. As a Software Engineer with 10+ years of experience, I specialize in building backend systems, APIs, and automation workflows using Java and Spring Boot. I’ve deployed scalable services on Google Cloud Platform (GCP), implemented secure authentication with OAuth2 and JWT, and automated data flows using KNIME and Power Automate. I have professional experience in Android development using Java, and apply strong testing and data governance practices across every solution I deliver.
