How I can help

What you can hand me

Whether you are hiring for a team or need a system built, these are the pieces of work I take end to end.

01

Backend & API engineering

Production REST APIs with authentication, role-based access, caching and the indexing work that keeps them fast under load.

  • REST API design
  • Auth & RBAC
  • Redis caching
  • Database modelling
02

Full-stack product build

An entire product from schema to screen, the kind of multi-role platform that StaySync and QuickKart AI are.

  • Next.js + Node.js
  • Payments & notifications
  • Admin dashboards
  • Deployment
03

Data pipelines & integrations

Automated ETL from third-party APIs, event-driven processing and the analytics layer that makes the data useful.

  • ETL pipelines
  • Third-party integrations
  • Event processing
  • Recommendations

About

Background

I am a software developer studying B.Tech in Artificial Intelligence at Newton School of Technology, Rishihood University. Most of my work sits on the backend: REST APIs, authentication and access control, caching, and the database design that decides whether any of it holds up.

Two internships taught me the part that personal projects cannot: working in a codebase somebody else designed, having my code reviewed, and shipping to a deadline. Contributing to Apicurio Registry and OpenEverest took that further, writing against standards set by maintainers I have never met.

Alongside that, 430+ solved problems and a 1558 contest rating on LeetCode keep the fundamentals sharp. I care about software that is reliable and fast, and that solves a problem somebody actually has.
