Projects

Career Roadmap & Skill Gap Analyzer
Tools Used: Java, Spring Boot, Hibernate, MySQL, REST APIs, Layered architecture
  • Designed and implemented backend services with Spring Boot following a layered architecture to separate controllers, services and repositories for maintainability.
  • Modeled persistent entities and optimized database access using Hibernate and MySQL to reduce redundant queries and improve response consistency.
  • Built modular REST APIs to expose user skill profiles, roadmap recommendations and gap analysis endpoints for frontend integration.
  • Applied clean code practices and repository patterns to keep codebase modular and reusable across features.
Online Quiz Platform
Tools Used: Java, Spring Boot, REST APIs, MySQL, Controller-Service-Repository architecture
  • Developed RESTful endpoints for quiz creation, question management and score tracking using Spring Boot.
  • Implemented Controller-Service-Repository layers to isolate business logic and data access, enabling straightforward feature extension.
  • Designed API contracts to support concurrent users and future scalability, focusing on stateless request handling and efficient DB interactions.
  • Integrated validation and exception handling to ensure robust request processing and clear API error responses.
Student Management System
Tools Used: Java, JDBC, MySQL, OOP, SQL
  • Built a CRUD application managing student records using Java, JDBC and MySQL with emphasis on modular design and OOP principles.
  • Optimized SQL queries and indexing strategies to improve data retrieval performance for common listing and search operations.
  • Implemented structured exception handling and input validation to harden the application against invalid data and runtime errors.
  • Documented database schema and module interactions to simplify handover and future maintenance.
Distributed Task Manager
Tools Used: Java, Multithreading, Concurrency, Synchronization
  • Implemented concurrent task execution using Java multithreading and synchronization primitives to model distributed worker behavior.
  • Designed thread-safe data structures and coordination mechanisms to avoid race conditions and ensure correct task processing.
  • Used logging and stepwise debugging to validate concurrency flows and identify bottlenecks in task scheduling.
  • Captured learnings on thread contention and applied them to improve responsiveness in simulated load scenarios.
