About

I’m Tharun Balaji, a Software Development Engineer with experience in Android and Full-stack development. I graduated with a B.E. in Computer Science from Chennai Institute of Technology and currently work as an SDE at Juspay. My core development experience includes Java, Kotlin, Android, Jetpack Compose, Kotlin Coroutines, Flutter, Node.js, TypeScript, Spring Boot, PostgreSQL, and MySQL. I’ve also worked with Docker, AWS, Jenkins, GitHub Actions, and CloudFront. I’m particularly interested in backend engineering, system design, distributed systems, APIs, databases, and cloud infrastructure. I actively practice Data Structures and Algorithms to strengthen my problem-solving fundamentals. I’m also exploring Generative AI and Agentic AI, with a growing interest in building, orchestrating, evaluating, securing, and deploying AI-powered systems using technologies such as Google ADK and Google Cloud. Outside of day-to-day engineering, I’ve been actively involved in developer communities. I was part of the GDSC CIT Core Team and co-founded Edu Engineering, an engineering-focused learning community with 12K+ members. Building, learning, and continuously improving as a software engineer. 🚀
