Open to full-time roles and freelance projects
I'm Umair, a MERN and Next.js developer in Lahore with 1+ year of professional experience. I design MongoDB schemas, build secure REST APIs with JWT authentication, and ship responsive React front ends for products where every role gets its own dashboard.

MERN · Next.js · TypeScript
Schema, API, UI and deployment. I take a feature from the first model to the last loading state, so nothing falls between frontend and backend.
JWT authentication, role-based authorization and ownership checks on the server, with route guards on the client. Hiding a button is not security.
Platforms where an admin, a manager and a customer each see a different app, built on one codebase and one API.
OpenAI API integrations and AI coding tools in the workflow, with the key on the server and every generated line reviewed and tested.
01 / Selected work
Four full stack applications and four front-end builds. The source for every one is on my GitHub, and each card opens a short case study.

02 / Try it
Pick a role and send a request. The menu, the permission table and the API response all come from one rule set, which is how I structure access control in a real backend.

05 / About
I trained in the MERN stack at PNY Trainings and have spent a little over a year in software houses, working on role-based web applications. Most of that work followed one pattern: one login, several dashboards, and a backend that has to decide who is allowed to see and change what.
That is the kind of problem I enjoy. I like owning a feature from the database schema and the API to the screen the user touches, and I care about the unglamorous parts: validation, access checks, loading and error states.
I also use AI in my daily work, both inside products through the OpenAI API and as a coding assistant. I read and test what it writes, because the code I commit is my responsibility.
01
Who uses this screen, and what are they allowed to do? Answering that first saves a rewrite later.
02
Every rule that matters is enforced in the API. The UI only reflects it.
03
Loading, empty and error states are part of the feature, not polish for later.
