Shajar Hussain

I’m a software engineer focused on shipping reliable, well-tested products end-to-end. I’ve already delivered production-style web applications through internship work and hands-on projects that blend full-stack development with applied machine learning.

At DataX Technologies, I built MY CAB RMS, a live multi-user rental management platform for a real client. I designed a guided multi-step rental wizard with live validation, enforced role-based access control, and implemented financial reporting with correct payment-state handling (Paid/Partial/Pending).

I also worked on the “make it production-ready” details—real-time fleet availability, double-booking prevention, and a return-and-settlement flow that regenerates official agreements. To improve performance, I diagnosed bottlenecks, reduced redundant Firestore listeners, and deferred Firebase Auth initialization, then added a Vitest unit test suite and resolved ESLint type-safety issues.

Beyond that, I contribute across the stack and into applied AI. I built PakFlood AI, a map-based flood intelligence dashboard using FastAPI, PostGIS, and machine learning models, and I develop structured, testable code with modular API/repository/adapter layers. I’m now seeking a remote software engineering role where I can keep delivering thoughtful UX, solid backends, and dependable automation.
