Java, Spring Boot, NestJS and React.js — from the schema and the access rules up to the screen someone actually uses.
Java, Spring Boot, Node.js, NestJS, React.js and MySQL.
REST design, JWT, bcrypt and role-based access control.
React.js and Ant Design — reusable, fast, cleanly structured.
Agile SDLC end to end, documented in Swagger and tested.
I am a full stack developer working across Java, Spring Boot, Node.js, NestJS, React.js and MySQL, building web applications that have to hold real data and real users. Most of my work sits where the API meets the interface: REST design, authentication and authorization with JWT, role-based access control, and database-driven application design.
On the frontend I work in React.js and Ant Design with a bias toward reusable components, performance and a clean structure that survives the second year. I have carried features through the whole software development lifecycle — requirement analysis, development, testing, debugging, deployment and maintenance — in Agile teams.

A full stack social platform with authentication, profile management and messaging. Real-time chat over WebSockets, REST APIs in NestJS on MySQL, and a reusable React.js and Ant Design component layer underneath it.
Video listing and playback built in React.js against REST APIs, with routes protected by JWT authentication and component rendering tuned for a smoother interface.
Backend APIs for shared-room expense tracking, settlements and member activity, with authentication and authorization workflows over a scalable API structure.
Full stack work on two products in production — a human resource management system and the supplier side of an apparel ERP. Below is what I actually built.
Employee management, recruitment, attendance, leave management and role mapping, built end to end.
React · NestJSAccess control across employee data and system entry points, tightening who can reach what.
NestJS · JWTXapperal ERP: supplier create, update and activation, plus supplier-to-user mapping workflows.
Node.js · MySQLPurchase orders with Excel upload, validation, approval, rejection and revision tracking; packing lists through lot, batch and dispatch.
NestJS · ExcelSwagger across both products and Postman suites behind it — the thing that made frontend and backend stop guessing at each other.
Swagger · PostmanI am open to full stack roles and interesting problems. The fastest way to reach me is email — I answer everything.
