Hi, my name is

Abdullah Rafi.

I build things for the web.

Lead Frontend Engineer with 5+ years of experience building production-grade React and TypeScript applications. Specialized in large-scale architecture, B2B SaaS, and AI-powered platforms. Currently building Airwork AI.

01.About Me

I'm a Software Engineer based in Rajshahi, Bangladesh with 5+ years of experience building production-grade web applications. I hold a Top Rated badge on Upwork from 4 years of freelance delivery.

My focus is on large-scale frontend architecture, migrations, and scalable UI development across B2B SaaS, healthtech, and AI-powered platforms. I enjoy turning complex problems into elegant, performant interfaces.

I've shipped complex features across the stack — from auth systems and payment integrations to real-time workflows and AI tooling — with a strong emphasis on performance, scalability, and clean state management.

Here are some technologies I've been working with recently:

  • TypeScript
  • React.js
  • Next.js
  • React Native
  • Redux / Redux Toolkit
  • React Query
  • Node.js
  • Express.js
  • Tailwind CSS
  • Zod
  • Jest
  • GraphQL
  • WebSocket
  • OpenAI APIs
  • Stripe
  • MongoDB
  • PostgreSQL
  • Firebase
  • Expo
  • CI/CD

02.Where I've Worked

Lead Frontend Engineer @ Airwork AI

Feb 2025 – Present · Bangladesh (Remote)

  • Architected and led frontend development of a full-scale B2B SaaS platform from scratch with dual portals (organizations and talent) using Next.js, React, and TypeScript.
  • Designed a resilient authentication system with Google OAuth, HTTP-only cookie sessions, and a request-queuing mechanism for token refresh to eliminate race conditions on concurrent API calls.
  • Integrated Stripe subscription billing with upgrade/downgrade flows, Stripe Elements for secure card entry, and payment method lifecycle management.
  • Established an OpenAPI-first pipeline auto-generating TypeScript SDK, Zod schemas, and typed hooks from backend spec — eliminating manual API sync overhead.
  • Implemented full-funnel analytics using PostHog and Meta Pixel, including React Query error tracking and conversion event capture.
