Muhammad is ready for their next project!
Most off-the-shelf POS software charges monthly fees, locks you into their hardware, and still doesn't fit your exact workflow.
I build custom POS systems. You own the code. No subscriptions, no vendor lock-in.

The Setup: A standard build includes a 3-screen ecosystem (customer kiosk, kitchen display, and waiter app) with instant real-time sync, smart inventory logic, and an admin dashboard. Deployed on Vercel and handed off with a clear written guide.
Pricing: Based on scope. A setup similar to my demo project runs $900–$1,200. Smaller builds cost less, while larger projects are quoted by milestone.
How I Work: Fully async. Requirements, feedback, and approvals are handled entirely in writing. No unnecessary meetings.
The service is listed on my profile. Send over your requirements and I will put together a custom breakdown.

"Can I see it in blue?" shouldn't require a back-and-forth email chain.
I build interactive 3D product configurators that run right in the browser. Drop in your model, and your customers can rotate, zoom, and swap colours or materials instantly—fully optimized for mobile.
Performance: All textures are generated procedurally via the Canvas API instead of loading heavy images. It stays lightning-fast without sacrificing visual quality.
B2B Ready: Includes a built-in PDF export. One click snapshots the user’s exact configuration and generates a clean quote sheet for internal team sharing.
Deliverables: You get the full repository, Vercel deployment, and clean written docs. No endless handover calls needed.

Restaurants still taking orders on paper is wild to me.
I built a custom, real-time ordering system that syncs instantly across 3 screens (customer kiosk, kitchen display, and waiter app). No refresh buttons or delays.
Stack: Next.js, Supabase Realtime, WebSockets, Zustand, and Tailwind.
Smart Inventory: When stock hits zero, the item automatically flips to "Sold Out" across every screen. No one has to remember to do it manually.
Admin Dashboard: Manage the full menu, toggle items, adjust prices, and check daily sales—no code needed.

Custom 3D Interactive Product Configurator
0
0
In this project, I made "Straw Struck," a high-performance interactive 3D configurator built for B2B ordering. This web app allows users to customize every aspect of a product in real-time—from dimensions and colors to material wrappers—and instantly generates a downloadable PDF quote with a screenshot of their custom design.
🚀 Key Features:
- Real-Time 3D Visualization: Built with React Three Fiber, featuring dynamic scaling and geometry swapping (Straight vs. Flexible).
- Procedural Textures: Zero image assets loaded! All textures (Paper, Film, Concrete) are generated programmatically via the Canvas API for infinite resolution and fast loading.
- Smart Validation: Enforces manufacturing constraints (MOQ, Length limits) automatically.
- Instant PDF Quotes: Uses jsPDF to capture the 3D scene and generate a professional order summary on the fly.
- Responsive Design: Fully optimized split-screen UI using Tailwind CSS that works seamlessly on mobile and desktop.
🛠️ Tech Stack:
- Framework: React 18 & Vite
- 3D Engine: React Three Fiber (Three.js / Drei)
- Styling: Tailwind CSS & Framer Motion
- State Management: Zustand / React Hooks
- PDF Generation: jsPDF
