I built REST APIs and optimized database queries for academic content platforms as a freelance full-stack developer, improving response time by 30%.
On the Distributed University Microservices Platform, I designed a Spring Boot microservices architecture for university academic resources and implemented Kafka-based communication between services.
I automated CI/CD with GitHub Actions and Docker for AWS EC2 deployment, and integrated Zipkin tracing, Redis caching, and ClamAV scanning.
I also built a platform for filtering previous-year university papers, using Redis caching and rate limiting to improve backend performance.
