}- I design and build full-stack web applications — REST APIs in Spring Boot on the backend, React on the frontend, MySQL underneath.
- My strongest project, Shopcart, is a two-sided e-commerce platform with JWT authentication, role-based access, Razorpay payments, and Cloudinary image hosting — architected and documented end-to-end.
- I'm currently sharpening my Java + Spring Boot fundamentals and system-design thinking, aiming for backend/full-stack SDE roles.
- Alongside project work, I keep up consistent DSA practice in Java, with 260+ problems solved across arrays, strings, hashing, and two-pointer patterns.
- Outside of core dev work, I like exploring real-time systems (WebSockets, collaborative tools) and clean API design.

Only technologies I have shipped in real projects are listed above. Anything from your resume that isn't reflected in a public repo yet — add it here and I'll fold it in.
|
A two-sided e-commerce app with independent customer and seller experiences — the most complete full-stack build on the profile. Stack: Java 17 · Spring Boot 3.3 · Spring Security · JWT · MySQL · Hibernate/JPA · React 19 · Vite · Tailwind CSS · Razorpay · Cloudinary · Docker Key features
|
Frontend Repo · Backend Repo · Live Demo A decoupled client/server app for live, multi-user drawing — built as a separate frontend (React/Excalidraw-based canvas) and backend (Java, containerized with Docker, deployed on Render). Stack: Java · Docker · Render · JavaScript · Excalidraw Key features
Note: both repos currently ship without a README — recommended next step below. |
|
An actively maintained problem-solving log — 260+ solved problems, primarily in Java with a few in C++. Stack: Java · C++ What it shows
|
A React + Vite frontend project, deployed live. Stack: React · Vite · JavaScript Note: the repo still ships the default Vite/React template README — see recommendations below before pinning this one. |
🏆 GitHub Trophies
- 🏗️ Shipped a production-style full-stack app (Shopcart) with real payment integration, image hosting, and role-based security — not a tutorial clone.
- 🧩 100+ DSA problems solved in Java, tracked with consistent commit history.
- 🔌 Built and deployed a split client/server system (real-time whiteboard) with independent, containerized backend deployment.
- 📚 Currently deepening Spring Boot, system design, and Java backend fundamentals for full-stack/backend SDE roles.
No public open-source contributions yet — all repositories above are original, independently built projects. (If you've contributed to any external repos, send the links and I'll add a dedicated section with contribution badges.)
