I'm a full-stack engineer. I turn software ideas into short lessons. Scroll to meet the first one: a working JavaScript event loop, built as a factory you can run.
Every machine here was modelled and lit in Blender, then loaded into this page. Click it to switch it on. Add your own functions and watch where they go.
Hundreds of objects, bevelled and built one by one in Blender: tower, cranes, belts and halls.
Cycles bakes the sun, the sky and the soft shadows into three 4096 px images, shown here.
Cranes, lift, wheel, belts and crates are separate parts, moved live by the event loop.
A small engine plays the real rules of the loop. It matched Node.js on 299 of 300 random test programs.
I'm a full-stack software engineer based in Pakistan, with five years of experience. I build Shopify and BigCommerce apps for merchants, web apps from front to back, and interactive 3D on the web. Then I turn the hard parts into short lessons on YouTube.
I build full stack applications that are ready for real users, and I take them through the whole software development lifecycle: planning, design, build, testing, release and upkeep. The screen you click, the API behind it, and the database under it.
I have worked on almost every area of Shopify and BigCommerce: theme extensions, customer account extensions, Shopify Functions, admin extensions and custom public apps, plus B2B products where merchants sell to other businesses.
I use my experience in three.js, WebGL and Blender to build immersive, creative websites. The models are made in Blender, drawn in the browser with three.js, and directed with GSAP, so scrolling tells a story. You are scrolling one right now.
Hard concepts, easy lessons. I turn the hard parts of what I build into short animated lessons, so a tricky idea takes a few minutes to understand. Find them at @FahmeedQayyum.
Follow one request down through five layers.
Some of it is live and some is no longer public. Where I cannot show code, I explain the problem and the approach.
Interfaces built in React and Next.js with JavaScript and TypeScript, from store pages on Shopify to interactive 3D scenes in the browser.
The services the screen talks to: REST APIs, an API gateway, Python backends and the Shopify and BigCommerce APIs.
Signing in and knowing who is asking, wired into the applications I have built.
Payment flows connected to the app, so a customer can pay and the app knows it happened.
The cloud that holds it up: AWS serverless services, cloud storage and the integrations between them.
B2B e-commerce products across Shopify and BigCommerce: full-stack work, platform integrations and custom extensions, in real production codebases.
Six applications across web, mobile and cloud: full stack development, third party integrations and an AWS serverless learning management system builder.
Full-stack web applications with Python backends, REST APIs and cloud storage, plus specialised software for laser imaging and interactive 3D.
I take on client work and build it end to end: planning, design, build, testing and release. Tell me what you need and we start from there.
Hover or tap a chip for one line on it.
Five groups. The same fifteen tools.
One task, seven stations. Scroll to send it down the line.
One task climbs seven floors, from the brief to the finished post. Scroll up the tower, drag to look around, click a machine, or send your own task and watch it go.
A scripted diorama made in Blender. The tickets and clips are not real work.
Scroll along the line: from a rough idea at the desk to a lesson on YouTube and a post on LinkedIn.
Each lesson starts with one hard idea. I research it, run the code myself, and keep only what I can show working.
The script is short, plain sentences, so a tricky idea takes only a few minutes to follow.
I record the narration at my desk. Then the audio is checked against the script, sentence by sentence, so each picture lands on the right words.
Scenes, captions and animations are built with code and rendered into the final video. Then come the Shorts, thumbnails, titles and descriptions.
Lessons go to YouTube. Shorts, carousels, GIFs and dev log posts go to LinkedIn.
I learn by experimenting with new tools and sharing what I find, as lessons on YouTube and dev logs on LinkedIn.
New lessons land on the channel. Dev logs and carousels land on LinkedIn. Or run the lesson again, or climb back up the tower.
Four things I can start on. Scroll to print each slip.
An immersive 3D site, like the one you are scrolling. The models are made in Blender, drawn in the browser with three.js and directed with GSAP, so scrolling tells your story.
Apps for stores on Shopify and BigCommerce, built around how your merchants and customers actually buy, including B2B.
One focused page for a product, an offer or a launch, with motion where it helps tell the story and nothing that slows the visitor down.
A complete application taken through the whole lifecycle: planned, built, tested and released, from the screen to the cloud it runs on.
Three companies and four projects. Open a card to see more.
The next one could be yours.

A JavaScript lesson you can run
A working JavaScript event loop built as a factory. Its engine matched Node.js on 299 of 300 random test programs.
Seven floors, one scripted scene each
A tower where a brief climbs from intake to content: intake, research, spec, build, tests, tickets, content.
