Projects

Digital Wallet API

April 30, 2026 – Present

Developed secure wallet management REST API using Spring Boot with JWT authentication and RBAC. Implemented P2P money transfer with ACID-compliant transactions, handling Rs.10L+ simulated transaction volume. Built transaction history module with pagination, filtering, and sorting using Spring Data JPA Specifications. Secured 12+ API endpoints with Spring Security; documented with Swagger, achieving 100% API coverage.

URL Shortener Microservice

April 30, 2026 – Present

Built URL shortening REST API using Spring Boot, handling 1,000+ req/day with Base62 encoding and MySQL persistence. Implemented Redis caching layer reducing database hits by 70%; achieved average response time under 50ms. Achieved 85% code coverage with JUnit 5 and Mockito; containerized with Docker and deployed on Railway. Secured REST APIs with Spring Security (RBAC); implemented API versioning and centralized exception handling.

Key Strengths

Strong practical experience in Spring Boot, REST API development, and microservices architecture, as demonstrated by the URL Shortener and Digital Wallet projects.
Proven ability in database optimization (MySQL query tuning, Redis caching) and performance enhancement, evidenced by a 58% latency reduction at MobiKwik.
Proficiency in testing methodologies (JUnit, Mockito with high code coverage) and CI/CD pipeline setup (GitHub Actions).
Experience with Docker for containerization and cloud deployment on platforms like Railway and AWS EC2.
Solid understanding and implementation of API security principles (Spring Security, JWT, RBAC) and centralized exception handling.
Demonstrated problem-solving skills, including resolving production incidents and performing root cause analysis.
The candidate's technical skills are highly relevant for a Java Engineer role. However, the stated experience level (1 year) is a significant mismatch for a 'Lead Java Engineer' position, which typically demands extensive architectural, leadership, and mentorship experience not evident at this early career stage.
