Hey, I’m Nishan Rajak ✳
I build the parts you don’t see — the APIs, authentication, and data systems that make everything else work. Thoughtful architecture. Real-world applications.
UNDER THE HOOD
router.get("/projects", validate(querySchema), async (request, reply) => { const projects = await service.list(); return reply.send({ data: projects }); });01 / SELECTED WORK
Real problems, considered solutions. A selection of tools and products I’ve designed and developed.
Developer-focused utility hub with modular frontend architecture and productivity-driven tooling.
Built a unified developer utility hub with a modular Next.js frontend, combining clipboard management, code snippet storage, and productivity widgets in a single fast-loading interface.
Power-user GitHub command center with repo, PR, webhook, and job controls in one dashboard.
Product-focused full-stack application with scalable backend and polished frontend experiences.
NISHAN RAJAK DEVELOPER & CONSTANT LEARNER02 / A LITTLE ABOUT ME
I’m Nishu, a software engineering student fascinated by what happens behind the screen. The logic, the data, the small decisions that make a system work beautifully.
I focus on backend development — designing APIs, untangling authentication, and bringing structure to complex applications. I learn by building, and every project is a chance to do it a little better.
03 / HOW I BUILD
Clear boundaries, modular services, and APIs that are a pleasure to work with.
Node.js / Express / Fastify / TypeScriptThoughtful schemas, purposeful caching, and the right place for every piece of data.
MongoDB / MySQL / Prisma / RedisProtected routes, validated inputs, and error handling built in from the start.
JWT / Cookies / Middleware / RESTBuilding production-structured backend systems with modular architecture, secure auth, and scalable API workflows.
Contributed to backend architecture and built scalable RESTful APIs.
Developed a real-time collaborative tool focusing on backend performance.
