About Me

Hello! I'm Varun Kumar Medi, a Software Engineer with 5.7 years of experience designing and developing scalable full-stack applications using Java, Spring Boot, and modern front-end technologies in Agile environments. I specialize in building RESTful APIs, microservices, and cloud-native solutions across fintech, banking, automotive, insurance, and e-commerce domains.

I have hands-on experience with Google Cloud Platform (GCP), AWS, and Azure, designing and developing distributed data processing pipelines, near real-time event-driven systems, and cloud-native architectures using Kubernetes, Docker, Kafka, Pub/Sub, Dataflow, RabbitMQ, and Redis. I own end-to-end responsibility for code reviews, testing, CI/CD automation, monitoring, alerting, logging, performance optimization, and production support while collaborating closely with product managers, stakeholders, and cross-functional teams.

I hold a Master’s degree in Computer Science from the University of Illinois Springfield, and a Bachelor’s in Computer Science from Andhra University. You can explore my work on my GitHub and connect with me on LinkedIn.

Projects

BuildEstate – AI-Powered Real Estate Platform

GitHub

Developed a full-stack real estate marketplace with advanced property search, JWT authentication, and admin dashboards.
