The Phone Gesheft
Catalogue, cart and checkout for a kosher phone retailer, with category filtering, a comparison tool and a phone-finder quiz.
E-commerceSites that load properly, software that replaces the spreadsheet, and the plumbing nobody else wants to touch. Bring an idea, a half-built thing, or a site that should have been replaced two years ago.

Get in touchWe build the face of your business, and the machinery behind it.
The site your customers actually see and buy from — and the thing underneath that nobody sees at all. Usually both, for the same client.
Marketing sites and online stores at the front. Dashboards, desktop apps, factory stations and automation at the back.

E-commerceScan a barcode off a laminated sheet and the right label prints on the right printer. Fully offline, wall-mounted, PIN-protected admin, and a job history the office can filter and export.
Factory stationA game a whole room plays at once, with the microphone as the controller — the louder the crowd, the higher he jumps. Run for about 400 people off a single mic.
Live event gameSeveral hundred trip waivers filed into three different vendors’ systems in one pass, instead of one form at a time. We work out how each vendor’s form actually submits, then run the whole roster through it.
A fundraising campaign that never asks for money. Goal, gauge, leaderboard, sponsors and a hall of fame — the whole machine pointed at learning instead of dollars, running unattended on a screen in the room for a full season.
Campaign boardA licensed, fully offline check-printing application. A spreadsheet of payees goes in; checks come out on blank stock with the amount in words and a bank-readable MICR line, and every one is logged and reprintable.

Nothing built yet, just the thing you keep explaining to people. One call to scope it and price it, and you see it working in a browser before it’s finished.
Slow, wrong on a phone, impossible to edit, or simply older than your business. We rebuild it properly and hand you something you can keep running.
A developer who stopped answering, a redesign that broke it, a codebase nobody wants to open. We take it over and finish it.
Marketing sites, one-pagers and rebuilds that load fast, read properly on a phone, and are built to be edited later without calling us.
Catalogue, cart, checkout and the order admin behind it — including migrations off a template that stopped fitting.
The dashboard, the tracker, the thing your team currently does in a spreadsheet at 11pm.
Android and web apps, including for filtered and non-standard devices most developers won’t touch.
Paperwork, mail merges, PDF pipelines, reconciliation — the recurring work that shouldn’t be manual.
Devices, live-event systems, kiosks and displays for when the job leaves the browser.
We have experience with 10DLC, Supabase, Stripe, Netlify, Cloudflare, Resend, Twilio, Kotlin, Android SDK, ESP32, C++, Apps Script, Electron, PixiJS, Web Audio, PostgreSQL, Shopify, JavaScript, Telecom API, AppSheet — and much, much more.
Everything named here is running in something a client uses today. No logos we’ve never shipped with, no percentage bars, no “expertise”.
Send the messy version — half an idea, a broken site, a spreadsheet held together with tape. That’s the normal starting point, and the first conversation costs nothing.
