Finance Backend API Developer

(2026-03 - 2026-04)

• Architected a production-ready RESTful finance dashboard backend with 3-tier role-based access control (Admin, Analyst, Viewer) using Spring Security 6 and JWT stateless authentication.
• Engineered financial record APIs supporting income and expense tracking, category-wise breakdown, and monthly trend analytics; pushed all aggregations via SQL SUM and GROUP BY to the database layer for scalable query performance.
• Applied soft delete using a deleted-at timestamp to preserve financial data history; enforced BigDecimal (precision 15, scale 2) for all monetary fields to eliminate floating-point rounding errors.
• Built RESTful dashboard endpoints with configurable pagination and date-range filtering; secured all protected endpoints via JWT Bearer token validation using a custom request filter.
• Constructed GlobalExceptionHandler returning structured JSON error responses for 6 HTTP error codes (400, 401, 403, 404, 409, 500); enforced DTO pattern across all controllers to prevent password and entity field exposure.
• Configured dual Spring profiles – H2 in-memory for development and PostgreSQL with environment variable injection for production – enabling clean local setup and secure cloud deployment.

Quiz Master Pro Developer

(2026-02 - 2026-03)

• Built a RESTful online quiz platform with role-based access control for Admin and User roles using Spring Boot and PostgreSQL; deployed the backend service on Render.
• Designed relational database schema for Users, Quizzes, Questions, and Results with entity relationships using Spring Data JPA and Hibernate.
• Engineered end-to-end quiz attempt workflow: quiz browsing, question delivery, answer submission, automatic score calculation, and result persistence.
• Enforced DTO pattern for secure API responses and global exception handling; tested all 15+ endpoints using Postman prior to deployment.

Scholarship Management System Developer

(2025-10 - 2025-11)

• Constructed a backend web application to manage student scholarship applications with role-based access control for Student and Admin roles using Spring Boot and MySQL.
• Delivered RESTful APIs for scholarship CRUD operations with input validation and backend eligibility verification logic following MVC architecture.
• Integrated MySQL using JPA and Hibernate with full entity mapping; centralized exception handling for consistent API error responses.
