Frontend Engineer building responsive, scalable React.js and Next.js applications — with a quality-first mindset and 5 years of production experience

My Journey

I'm Muhammad Shumail, a Karachi-based Frontend Engineer with nearly 5 years of experience building responsive, scalable web applications using React.js, Next.js, and TypeScript.

At Cloud Primero B.V., I develop reusable UI components and responsive interfaces, integrate and validate REST APIs, and collaborate across design and development teams to deliver enterprise healthcare and education platforms.

My freelance work on Upwork (10+ international projects) and previous roles at Supersoft Technologies and Think Transportation gave me strong breadth across the full frontend delivery lifecycle — from requirements gathering through production deployment.

"Build with precision. Test to confidence. Ship with pride."

I bring a strong understanding of frontend testing, API validation, and performance optimization — enabling the delivery of reliable and maintainable products across enterprise and international client projects.

Outside client work, I run Ubuntu as my daily driver, manage my dotfiles with GNU Stow, and write Bash scripts to provision and maintain my own workstation — a second track I'm actively growing toward deployment and automation fundamentals.

Engineering Projects

Linux & Automation Roadmap

Personal systems work I'm building outside client projects — tracked here honestly as it happens, not presented as finished until it is.

In Progress

Ubuntu Dotfiles

Packaging my GNU Stow–managed dotfiles into a documented, public repo.

Why: I rebuild or reconfigure my environment often enough that redoing it by hand every time was wasting real hours — I wanted one command to get back to a working setup.

  • Daily-driver Ubuntu setup already managed with GNU Stow.
  • Currently cleaning up and documenting the repo so it's reproducible on a fresh machine.
Ubuntu
GNU Stow
Bash
Git
In Progress

Linux Automation

Bash scripts that provision and sync my Ubuntu workstation end-to-end.

Why: Manually re-provisioning a machine after every fresh install or migration got old — I wanted the setup scripted and repeatable instead of remembered.

  • Automates fresh-install setup — packages, shell config, SSH, and dotfiles.
  • Built to be one-command migration-ready when moving to a new machine.

Ubuntu
SSH
rsync
In Progress

Deployment Lab

A personal environment for practicing real deployment workflows.

Why: I wanted to understand deployment beyond a Vercel one-click deploy — what actually happens between a git push and a server serving traffic.

  • Base setup for the Docker, CI/CD, and VPS work below.
  • Goal: understand deployment beyond one-click platform deploys.
