About

I’m Anshar Ansharma, a Java back-end focused full-stack developer from Kolkata, with hands-on experience building production-ready web applications using Spring Boot and React. I’ve worked on secure authentication flows with JWT (including refresh token rotation), designed paginated APIs with sorting/filtering, and created React UIs with protected routes and dashboard visualizations.

I’m comfortable working across the stack—Dockerizing services, deploying backends, and integrating cloud PostgreSQL databases—while also implementing practical engineering standards like CORS configuration and global exception handling. Alongside my job tracking projects, I’ve built a console-based banking system in Java to strengthen my OOP and layered architecture skills, and I’m now seeking backend or full-stack roles where I can contribute and keep improving.

Work experience

Terminal Banking System (Console Project) · Personal ProjectMar 2026 – Mar 2026 · 1 mo

Developed a Java console-based banking system supporting account creation, login, deposit, withdrawal, and balance enquiry. Implemented session-based authentication using account number and password verification backed by in-memory HashMap storage. Applied OOP principles with a layered architecture separating service logic, authentication, and transaction handling into distinct classes. Added input validation for transactions including negative amount checks and insufficient balance handling.

Full Stack Job Tracking Application (Project) · Loom-APP (Linked project)Jan 2026 – Mar 2026 · 3 mos

Built and deployed a full-stack job tracking application with Spring Boot (REST APIs) and a React frontend. Implemented JWT authentication with refresh token rotation for secure session management, and added forgot/reset password flow using the Resend email API with a custom domain, including token expiry validation. The backend was Dockerized and deployed on Render, with Neon PostgreSQL as the persistent cloud database. On the frontend, implemented protected routes, paginated job listings, status filtering, and a live dashboard with bar charts. Configured CORS, global exception handling, MapStruct DTO mapping, and paginated REST APIs with sort and filter support.
