Fatih Bilgiç · 🌍 Worldwide
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.
I was born in Adıyaman, in south-eastern Türkiye; my family line comes from the village of Zey. I grew up there until adolescence, moved to Istanbul at twelve, and my schooling travelled from city to city after that. I never stayed long anywhere, and I tied my learning to my own attention rather than to an institution.
What moved me forward was not a particular school but the ability to manage my own attention. Learning a language and building a system follow the same method: turn the thing over until I understand it, then leave it running. Every address on this site is the output of that habit.
I am curious about people and about what is organic. Software, data, hotel revenue management, plant diagnosis, measuring how states behave: they look like distant subjects, but they all ask the same question. How does this actually work, and can I make it measurable?
The 2023 earthquake changed a great deal. After the loss I chose to work nomadically rather than settle. In recent years my digital ventures have grown into something that reaches other people, and my multidisciplinary way of working comes from there. I run several ventures at once today, and all of them are listed openly above.
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. A web version runs at brainwavegenerator.us.
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.
Dispatch, courier settlement and restaurant ledger on one screen, built for courier companies and restaurant chains.
Courier positions and the parcels they carry on a live map; automatic assignment scored on distance, load and availability. Customers get a tracking link that asks for no login. At month end parcel, kilometre, hour, bonus and night-shift pay are settled automatically with Turkish VAT and withholding, and the figures freeze once the period closes. Getir, Trendyol and Yemeksepeti orders flow into the same pipeline. A live demo runs without any setup.
Measures what states do rather than what they say: official gazettes are read daily and turned into a measurable unit of behaviour.
Over thirty thousand documents from the official gazettes of the US, Türkiye, the UK, Poland, Canada and the EU are collected, labelled and scored. Each regulation counts as a commitment of resources; cross-country targeting links and week-over-week change are drawn on a globe. The measured layer and the assumption layer are kept visibly separate, and the method and its limits are published on the site.
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 pricing engine that collects competitors' nightly rates and shows which nights are leaving money on the table.
Real rates are gathered every night from public Booking.com listings; each morning the hotel gets the nights worth acting on, ranked and each with its reasoning. The hotel sets its own floor and ceiling and the engine cannot step outside them; automatic push is off by default, so no rate leaves without approval. Currently a free pilot in selected cities.
UK tax calculators that show their working and cite the rules behind every figure.
Eleven calculators — take-home pay, the 60% trap, the child benefit charge, pension relief, student loan, Scotland versus England and self-employment among them — run on one shared engine. Every figure links to the HMRC rule that produced it. Fully static; nothing runs on a server.
An analysis tool that produces calibrated football probabilities and measures and publishes its own accuracy.
A time-weighted Dixon-Coles model trained, for every match, only on data known before kick-off. When it says 60%, the site measures whether roughly 60% of such matches actually end that way, and states on the front page that the model does not beat the betting market's closing line. It takes no bets, sells no tips and links to no bookmaker. Includes season simulation and a personal decision log.
A library of named, versioned, evidence-linked protocols for knowing yourself, governing yourself and building something that is yours.
Knowledge became cheap; knowing yourself accurately, governing yourself and composing something no one else can copy did not. StudyBrave makes those three operational as protocols, each published with its duration, cadence and evidence links, with a new one every two weeks. Built to be taken and left; no account required.
A free binaural beat generator that runs entirely in the browser, with no install and no account.
The web counterpart of the mobile app. Beat frequency from 0.5 to 40 Hz, carrier tone, binaural/isochronic/pure-tone modes, a white, pink or brown noise bed and a timer up to eight hours. Audio is synthesised on the device through the Web Audio API; nothing reaches a server. Separate players for sleep, focus and noise.
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.
A survival horror game set in an abandoned station. Escape mode and 4-player online co-op added. No ads, no analytics, no account. Live on iOS and Android.
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.
