I’m a Computer Science graduate who enjoys building backend services that are reliable, well-tested, and easy to maintain. I bring hands-on experience in backend software engineering, full-stack development, Python automation, and scalable data processing.

As a Graduate Engineer Intern at Zeta, I contributed to migrating production analytics from Amazon Redshift to Trino with Apache Iceberg. I also built Python automation tools and reusable SQL utilities to support workflow automation, validation, debugging, and migration.

I’m careful about correctness and production quality: I validated workflows using automated row-level and fingerprint validation, then investigated migration issues and collaborated with engineering teams to deliver dependable deployments. Working in an Agile environment, I focused on software quality, testing, and continuous improvement.

My projects reflect the same mindset. I designed RESTful backends with Java, Spring Boot, and PostgreSQL (including unit tests with JUnit/Mockito), built a Node.js/Express.js skill-sharing platform, and developed an AI-based multilingual mental health chatbot using Flask with the Gemini API and Cohere—integrating LLM APIs with prompt engineering.
