About Ahsan
Full Stack SaaS Developer | React TypeScript Firebase Node.js GraphQL
Lahore, Pakistan - 2:51 pm local time
I help founders and product teams ship React + Firebase + Node.js products faster, with production-ready architecture, clean UI, scalable data flows, and reliable releases.
Over the last 8+ years, I’ve built and shipped SaaS products, cross-platform mobile apps, browser extensions, and product ecosystems using React, TypeScript, Firebase, Node.js, Express, GraphQL, Capacitor, TailwindCSS, and Radix UI. My work focuses on real product delivery: fast interfaces, maintainable code, secure backend logic, and features that are ready for users, not just demos.
What I can help you with:
- SaaS web app development
- React frontend architecture and feature delivery
- Firebase backend, Firestore modeling, Cloud Functions, Auth, and analytics
- Node.js / Express APIs and GraphQL integrations
- Capacitor-based Android and iOS apps using React
- Browser extensions, including Manifest V3
- Product maintenance, scaling, bug fixing, and release support
Recent work includes:
- Perkforce — multi-tenant SaaS with web, Android/iOS, Slack, and Microsoft Teams integrations
Video Controls Plus — cross-browser productivity extension built with React, TypeScript, Firebase, Radix UI, and Manifest V3
- ZTools — 484-tool digital toolbox across web, Android, and browser extension, with 507 generated SEO pages in the latest verified build
- ClearHire — resume builder and verified-employment platform with 100 passing tests and 102 SEO-backed public routes in the latest verified state
- Files Hub — multi-tenant file platform with browser extension and TypeScript SDK, including 50 passing SDK tests in the current verified state
Clients hire me when they need someone who can understand product goals, work independently, communicate clearly, and ship production-ready features without constant hand-holding.
I’m available for both part-time and full-time work, and I’m especially interested in long-term product-focused collaborations.
