Cover image for Most off-the-shelf POS software charges

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. Video: https://youtu.be/iWXqQ44Gc94 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. https://contra.com/s/YlBXPZLm-real-time-pos-kiosk-and-kitchen-display-system-kds

"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.

Cover image for Restaurants still taking orders on

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. Watch it in action here: https://youtu.be/iWXqQ44Gc94 If you run a café, restaurant, or food spot and want a setup like this, you can check the link in my profile or message me directly.
