Built and maintained 12–15 RESTful API endpoints (Java, Spring Boot, Hibernate/JPA) consumed by frontend apps and 50–100+ internal users for CRUD, authentication, and reporting. Developed and integrated 4–6 backend modules (User Management, Student Management, Attendance, Assessment, Reporting) against SQL tables of 5,000–20,000+ records; automated validation cut manual verification effort by 30–40%. Investigated and resolved 30–40 backend issues (~2–3/week) through debugging, API validation, SQL analysis, and backend logic fixes; improved API response time by 20–30% and strengthened application stability. Collaborated in a cross-functional Agile team of 5–8 across 10–15 sprints, contributing to API documentation, test cases, debugging, code reviews, and deployment support. Mentored 400+ learners in Java, SQL, and backend application development, strengthening communication and teamwork skills.
