A record of work that shipped

Ragmux is a self-hosted, single-binary AI gateway that sits between your application and providers like OpenAI, Anthropic, Gemini, DeepSeek and Ollama. It exposes one OpenAI-compatible API, injects RAG context from the documents you upload into every request of a project that has a store linked, and keeps provider credentials encrypted and away from the application. Users, connections, projects, documents, vectors and metrics all live in one PostgreSQL with pgvector — no Redis, no separate vector database.

CommitBrief is a provider-agnostic Go CLI tool that performs LLM-powered local code review on git diffs. It reviews any scope — from staged/unstaged changes to a single commit to PR-style three-dot ranges — without leaving the terminal, without leaking the diff, and with customizable project rules.

BabelQueue is a language-agnostic message queue standard that lets services written in different languages share the same queue without getting trapped by serialization lock-in. Instead of language-specific formats like PHP's serialize(), it defines a strict JSON envelope — frozen at schema_version 1 — that every language can read natively. It runs on Redis and RabbitMQ with no sidecar or broker plugin, with an overhead target of under 2%.

Contextator is a self-hosted, multi-tenant documentation server that takes a project's documentation from wherever it already lives — a mounted folder, a git repository, an uploaded archive, an Obsidian vault or a Notion workspace — and makes it searchable behind a single MCP endpoint. Every project gets its own URL and its own document collection; embeddings are generated on the machine's CPU by default, and the documents never reach a third party.

QueryProxy is a self-hosted query approval portal I built so developers can reach production data without ever holding production credentials. Submitted SQL is parsed and guarded, runs on a queue once a DBA approves it, is masked as the results are written to disk, and every step lands in an immutable audit record.

academia.sh is a learning platform with free, no-signup lessons that never separates a lesson's theory from a real problem from the field. It's presented through a curriculum-course-topic-lesson hierarchy, progress and quizzes are measured per lesson without splitting theory from problem, and full-text search runs on Postgres; the course-end exam, certificates and study assistant sit in a Pro tier. Content lives in a separate GitHub repo; the first field is computer science, and the model was designed multidisciplinary from the start.

Devrazzi is a content product that leaves the signal/noise problem in developer news not to a human editor but to a layered model pipeline. It collects sources, runs a first pass locally with Ollama, hands off whatever clears the bar to a step-specific model among DeepSeek/Gemini/OpenAI/Claude, and produces and publishes a TR/EN synthesis end to end. Live on web and iOS; full article extraction isn't there yet, and that's kept open as a known limit.

Garajdaş is a community platform where every car make-and-model has its own club, keeping internal-combustion and electric vehicles under one roof. A single API schema is shared by the web (Next.js) and mobile (Expo/React Native) clients, the design system is defined in one file and synced by hand. The MVP phases are closed, the API has 97 tests; the platform is live.

Qurandia is a free, open reading and research resource that matches hadith datasets that don't know each other, trusting not a number but the letter-level fingerprint of the text itself; Quran- and hadith-centred. Translation, word-by-word analysis, tafsir, asbab al-nuzul, the hadith corpus and search all sit under one roof; direct number matching is only 0-14% consistent, while text fingerprinting pushes matching up to 91-99%. Turkish hadith translation coverage stands at 83% today.

A personal and corporate financial management platform. It offers income-expense tracking, budget planning, detailed reporting, and multi-account management.

SignalLock is a privacy-focused menu bar app that automatically locks your computer when you walk away from it — using a Bluetooth device you carry with you.

Regnarium fits the explore-expand-exploit-exterminate loop of 4X strategy into a single sitting, played offline in the browser. The 480-hex map closes after at most 60 turns, combat rolls no dice and the preview you see before attacking is the calculation itself; there are no accounts, no servers and no tracking.

sakinkal is a rational, evidence-based, and offline-accessible preparedness resource that strips crisis readiness in Turkey of fear and hype. It distills complex information into clear steps, checklists, and guides anyone can apply. 'No panic, just preparedness.' — a non-profit, ad-free, mission-driven publication.

TB1MSK is my call sign as a licensed amateur radio operator and my personal station/identity site; in its second phase, a blog where I produce Turkish content about amateur radio. From my station based in Çatalca/İstanbul (KN41ff), I use FM, repeaters, and APRS on the VHF/UHF bands, focusing on emergency communications and portable operation. At the intersection of radio and software: 'Signal in the air, code on the desk.'

I published a minimalist MVC framework (Framework3) alongside 30+ modular PHP libraries (Router, Database, Cache, Mailer, Socket, ...) under a single ecosystem; all packages are available on Composer/Packagist under the MIT license. The codebase complies with PHP-FIG standards and is backed by type safety, PHPUnit tests, extensive documentation, and examples.

Looplio — a recurring automation platform (Web + iOS + Android) that turns repeating tasks, maintenance, and checks into reusable templates and automatically generated checklists.

SilkWard is an offline puzzle game that resolves 36 levels plus 6 hidden levels on a node-and-edge board through entirely deterministic moves. A single TypeScript core feeds the web (PWA) and mobile (Expo) clients at once; level difficulty is measured by the minimum move count the solver-cli tool finds via BFS. It is playable today at silkward.com.

SysAdmin Crisis is a night-shift simulation solved with 29 gamified Unix commands, including real flags, Tab completion and man. The web (PWA) and mobile (Expo) versions share the same game engine; zero data collection is a constraint tied to the build chain. It is playable today at sysadmincrisis.com.

A platform dedicated to fashion, style, grooming, lifestyle, and health advice for men. Through a subscription system, it published a monthly online magazine alongside subscriber-exclusive content and comprehensive guides.
