I built SightShark, a SaaS web application with end-to-end user workflows, dashboards, APIs, search/filtering, and admin functionality.
Application Overview
The platform uses React + TypeScript on the frontend and FastAPI + REST APIs on the backend. I worked on authentication, user and workspace management, role-based access, client workspaces, interactive tables, search/filtering, data integrations, API-driven workflows, and automated data synchronization, with a focus on reusable components, performance, and maintainability.

"Zahid has successfully delivered and deployed HCM within our company."
That's from the client review that landed on my profile this week, for OneHub — the payroll and people-operations platform I built for TechFoundry. Monthly payroll with fiscal-year tax withholding, payslips and tax certificates on demand, expense reports read line by line by Claude, and one reporting layer so the dashboard, the payslip and the certificate always agree.
The word I care about in that review is "deployed". Delivered means the code works. Deployed means payroll runs on it every month, people are paid the right amount, and nobody has to call me.
The thing I'd do differently: the tax rules started out hard-coded. Fine for one country, one fiscal year — until it wasn't. We later pulled them out into a rules engine so the same payroll runs across countries without touching the code. Next time that's day one, not a refactor.
It's also a Contra-verified project — the work was paid through Contra, so the review and the case study are tied to the same engagement. Case study: https://contra.com/p/Y3EgrEUc-payroll-and-people-operations-platform
