Software workshop · Istanbul
Ertan Yeni
From idea to the App Store.
I spent six years building software for other people’s stores, back offices and websites. Now I build games and apps in my own workshop. Everything on the wall runs: two are on the App Store, two are on their way, two live in the workshop.
01 · Wall
Finished, framed, running.
Each poster is a product. Two are in your pocket, two are on their way, one is getting ready for the field, one keeps watch in the back room.
Calofeed
Take a photo of your plate and AI pulls out the calories, protein, carbs and fat in seconds. You can log a meal by voice too. See your friends’ plates, leave a reaction and race on the weekly leaderboard: calorie counting, but social.

Ink & PrintMürekkep Baskı
A color-sort puzzle set in a screen-printing shop. Separate the inks in the bottles; every finished color is printed onto the poster as a new layer. 90 levels and 90 Asian-inspired posters across the Workshop, Neon City and the Mountain Temple. There’s a cat on the shelf, and it has opinions about every move.

Damla
A block puzzle where the blocks are jelly. Each drop takes the shape of the gap you press it into; fill a row or column and the jellies pop. Dawdle, and after six moves they turn to stone. 30 levels on the map, the same Daily Drop for everyone every day and 12 jellies with big personalities to collect in the jar. In TestFlight now, the App Store is next.

PipeSentinel AI
It watches sewer camera footage frame by frame. A YOLO model I trained marks cracks, fractures, root intrusion and deposits; it reads the distance and slope overlay on each frame, builds a 3D model of the pipe as the camera moves forward and writes the damage report at the end. It works; I’m preparing the licensed version that companies install on their own machines.

RoyNight shift
Roy
My personal assistant, named after the replicant in Blade Runner; the workshop’s night watchman. It prepares the morning briefing, remembers where I left every job and does the legwork of research. It isn’t a public product: it’s an experiment that lives in the back room, and I’m still building it.
The sign lights up at night.The sign is on. Roy is on watch.
02 · Shelf
Proofs on the shelf.
Work from before the wall: live tools, systems in the field, open-source experiments.

Digital logic simulator
A circuit simulator in the browser: a 4-valued logic engine, live debugging, 47 lessons, a 90-term glossary and Verilog export.

WorkspaceBrain: GitHub - P.04
AI Usage Widget
macOS utility
A native app that shows Claude, OpenAI and Cursor usage on the desktop and in Notification Center. You see what you used the same day, not at month end.
AI Usage Widget: GitHub - P.05
Bloomberg Terminal
Finance UI experiment
An AI-assisted terminal experiment that puts market data, news, volatility and a watchlist on one screen.

Behind the bench.
I’m Ertan. I work full-stack: React and React Native on the front, .NET Core and Python on the back, PyTorch when something needs to see, and lately SwiftUI and Godot. My favourite part is spotting where a job snags in the real world and building the tool that fixes it.
A handheld that prints shelf labels in a store and a film puzzle on your phone started with the same question: who is going to use this, where, and with which hand?
