Profile

Senior full stack developer building scalable web, mobile, desktop, SaaS and enterprise applications with React, Next.js, React Native, Node.js, Express, Electron, MongoDB, PostgreSQL and modern cloud infrastructure. I have delivered production food-delivery platforms, POS systems, SaaS products, desktop apps, real-time applications and cross-platform mobile apps for startups and international clients — designing the interfaces, building the REST APIs, running the cloud deployments and keeping the CI/CD pipelines that carry them.

Experience

Full Stack Developer (MERN)

Jul 2022 — Present · 4 years 4 months

Liefermars.de · Full Time · Ludwigshafen, Germany · Remote

I build and run a multi-vendor food marketplace's Android and iOS apps, and the servers they live on.

  • Keep ordering, live menus and payments running in production across both platforms.
  • Built the customer apps for Android and iOS from scratch, plus a real-time order terminal for restaurant staff that prints delivery receipts.
  • Built the Liefermars POS portal — POS vendors connect their own terminals through it to integrate the Liefermars marketplace, so Liefermars orders arrive straight into their POS.
  • Own the release path: AWS EC2 infrastructure, Jenkins pipelines, and the store updates that go out with them.

Senior Software Development Engineer

Jan 2019 — Present · 7 years 10 months

Freelancer.com · Freelance · Karachi, Pakistan · Remote

Client work from brief to delivery: I take the vision, shape the interface, and ship the finished product.

  • Turned Figma files and rough wireframes into live, mobile-first builds — no gap between design and production.
  • Integrated logins, maps, analytics and payment flows against third-party APIs on live accounts.
  • Work continues until the client is happy; most of my contracts come from repeat hires.

Built and maintained the APIs two frontend teams depended on, plus the SaaS products running on them.

  • Created and maintained robust APIs in Node.js and Express, with auth, validation and data modelling right from the first schema.
  • Replaced ORPC with tRPC and built a Hono API as the backend service; converted React apps over to Next.js.
  • Managed CI/CD pipelines and Hetzner VPS infrastructure, and kept a shared SaaS starter kit current and fully typed.

Frontend architecture for a software testing product and the scheduling tools around it.

  • Built reusable UI components and the React libraries around them — Slide View and Table Grid — on object-oriented programming principles.
  • Implemented Vue.js components and reusable functions, carrying the same patterns across the Vue codebase.
  • Worked closely with the backend teams — Redux carried the state management on the frontend.
