Fatih Bilgiç · Istanbul
I build my own products and take on selected client work. Behind every line below there is a live address or a store page you can open right now. Addresses, not numbers.
All of them are live and on me: the server, the database, the backups, the updates. Each card opens the product itself.
An app that generates binaural audio in real time for sleep, focus and calm.
It plays no pre-recorded tracks — the tone is synthesised on the device, so frequency and duration stay fully under the user's control. The progressive wake-up alarm runs in the background. Live on iOS and Android.
Management platform that puts an auto repair shop's work orders, stock, cash and vehicle records on one screen.
Work-order wizard, barcode point of sale, receivables and cash tracking, vehicle records keyed to plate and VIN, role-based permissions. Runs as a hosted subscription or self-hosted on the shop's own server. Per-tenant document numbering, nightly automated backups.
A multi-tenant commerce platform built so AI agents can operate it directly.
The storefront exposes itself to agents as well as people: catalogue and order flow are published as tools over an MCP server. Product search is semantic, tenant isolation is enforced at the database level with row-level security, and the payment and e-invoicing plugins are written for the Turkish market.
This project is in closed development — its name and address are not shared.
Mobile app and service that identifies plants and diagnoses plant disease from a photo.
Inference does not go out to a third-party vision API — the models run on my own server with my own weights. Care schedules and reminders live in the app.
A business directory and lead-capture platform for dog trainers.
Signup, email verification, password reset, roles, photo upload, premium upgrade and a dynamic sitemap — written with no npm packages at all, only Node's own built-in modules. The whole database is a single SQLite file.
Every app here is genuinely published, and each badge links straight to its own store page.
A fully offline disaster-preparedness guide built for Turkey. 14 disaster types, a 125-step decision tree, first aid and an emergency call list — all on the device, because there is no time to download anything when an earthquake hits.
A dual-joystick space combat game with asteroid fields, upgrades and global leaderboards.
Server administration from a phone: SSH and SFTP, an xterm-compatible terminal, and keys held inside the iOS Secure Enclave. It reconnects itself when a session drops.
An atmospheric survival horror game. Entirely offline and collects nothing — no ads, no analytics, no account.
Math practice for young children. No account, no ads, no data collection — progress stays on the device.
An assistant that identifies plants and diagnoses disease from a photo. The models run on my own server.
An offline fixture and match simulator for the 2026 tournament. Team data ships inside the app; no connection needed.
Sites and back-office panels businesses use daily. All still standing, and I still maintain them.
A corporate site, four back-office panels the staff use daily, and an automated outreach campaign.
Hundreds of city and service pages are generated programmatically. Every weekday morning a campaign engine sends staggered outreach email to an institution list, with send intervals and daily caps tuned to provider limits.
A fully static lead-generation site, generated separately for all 81 provinces.
A templated build with its own page for every province and district. Nothing runs server-side, which makes it both very fast and nearly maintenance-free.
A business site plus the panels that run daily operations: invoicing, incident records, verification, job portal.
I wrote Python generators that produce a page for every district × brand × service combination. This engagement is the first version of the problem that later became Cosmor.
A studio site published in Turkish and English — discography, equipment, before/after listening demos.
A complete mirrored structure for both languages, plus a structured site description so language models read the site correctly.
A five-language site for a holiday property in the Dolomites.
Italian, German, English, Korean and Chinese. The booking flow connects to the property's existing system. I also built an internal tool that reads incoming enquiry email and prepares the offer automatically.
Dynamic pricing, a multilingual guest assistant, review analysis and demand forecasting in one system. My hotel revenue work runs through this partnership; the technical detail lives on Nexorev.
Open-source experiments — they are not finished products and I am not claiming they are.
An experimental AI engine built on quantum computing primitives.
Quantum circuit simulations on IBM Qiskit.
Electromagnetic field analysis with FastAPI, React, PostgreSQL and TensorFlow.
A kernel-level residual-data protection experiment written in C.
A new idea, a partnership, or a problem with a system already running — whichever it is, write to me. I usually read messages the same day.
