# Portfolio > Shipped SaaS products, open-source packages and content publications. What each project does, what it runs on and whether it is still maintained. - Project count: 19 - Source: https://muhammetsafak.com/portfolio/ - Language: en-US - Author: Muhammet Şafak --- ## Project classes - **Flagships** (5) — The brand-defining products I invest in most. - **SaaS Products** (2) — Subscription-based software products in production. - **Older / Hobby Projects** (5) — Open-source and personal projects I built in the past. - **Side Publications** (7) — Content-focused publications, magazines and platforms. ## All projects ### Main Focus In active development; the products I spend most of my time on. #### Ragmux - 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. - Role: Founder & Developer - Class: Flagships - Tier: Main Focus - Status: Ongoing - Started: 2026-09-18 - Technologies: Go, PostgreSQL, pgvector, ParadeDB, Docker, OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Ollama, Prometheus, OpenTelemetry, Cohere, Voyage AI - Website: https://ragmux.com - Source code: https://github.com/ragmux/ragmux - https://muhammetsafak.com/portfolio/ragmux/ - Markdown: https://muhammetsafak.com/portfolio/ragmux.md #### CommitBrief - 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. - Role: Founder & Developer - Class: Flagships - Tier: Main Focus - Status: Ongoing - Started: 2026-04-07 - Technologies: Go, Cobra, go-git, Anthropic Claude, OpenAI, Google Gemini, Ollama, YAML, Goreleaser, Astro, Tailwind CSS - Website: https://commitbrief.com - Source code: https://github.com/CommitBrief/commitbrief - https://muhammetsafak.com/portfolio/commitbrief/ - Markdown: https://muhammetsafak.com/portfolio/commitbrief.md #### BabelQueue - 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%. - Role: Founder & Developer - Class: Flagships - Tier: Main Focus - Status: Ongoing - Started: 2026-06-15 - Technologies: JSON, Redis, RabbitMQ, PHP, Python, Go, Node.js, Java, .NET - Website: https://babelqueue.com - Source code: https://github.com/BabelQueue - https://muhammetsafak.com/portfolio/babelqueue/ - Markdown: https://muhammetsafak.com/portfolio/babelqueue.md #### Contextator - 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. - Role: Founder & Developer - Class: Flagships - Tier: Main Focus - Status: Ongoing - Started: 2026-09-17 - Technologies: TypeScript, Node.js, Fastify, PostgreSQL, pgvector, Drizzle ORM, MCP, transformers.js, Docker, Notion API, Vitest, Biome - Website: https://contextator.com - Source code: https://github.com/Contextator/Contextator - https://muhammetsafak.com/portfolio/contextator/ - Markdown: https://muhammetsafak.com/portfolio/contextator.md #### QueryProxy - 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. - Role: Founder & Developer - Class: Flagships - Tier: Main Focus - Status: Ongoing - Started: 2026-09-08 - Technologies: PHP, Laravel, Livewire, Blade, Tailwind CSS, Vite, CodeMirror, phpMyAdmin SQL Parser, Pest, Docker, GitHub Actions, PostgreSQL, MySQL, MariaDB, SQL Server, SQLite - Website: https://queryproxy.com - Source code: https://github.com/QueryProxy/QueryProxy - https://muhammetsafak.com/portfolio/queryproxy/ - Markdown: https://muhammetsafak.com/portfolio/queryproxy.md ### Active Development Still gets new features and updates, but isn't the main focus. #### academia.sh - 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. - Role: Founder & Author - Class: Side Publications - Tier: Active Development - Status: Ongoing - Started: 2026-09-23 - Technologies: Laravel, PHP, Livewire, Blade, Tailwind, PostgreSQL, Redis, Filament, Pest - Website: https://academia.sh - https://muhammetsafak.com/portfolio/academia/ - Markdown: https://muhammetsafak.com/portfolio/academia.md #### Devrazzi - 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. - Role: Founder & Developer - Class: Side Publications - Tier: Active Development - Status: Ongoing - Started: 2026-09-23 - Technologies: TypeScript, Node.js, Prisma, PostgreSQL, Ollama, DeepSeek, Gemini, OpenAI, Claude, Fastify, Astro - Website: https://devrazzi.com - App Store: https://apps.apple.com/us/app/devrazzi-curated-tech-news/id6790693413 - https://muhammetsafak.com/portfolio/devrazzi/ - Markdown: https://muhammetsafak.com/portfolio/devrazzi.md #### Garajdaş - 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. - Role: Founder & Developer - Class: Side Publications - Tier: Active Development - Status: Ongoing - Started: 2026-09-23 - Technologies: Laravel, PHP, PostgreSQL, Next.js, React, Tailwind CSS, Expo, React Native, TypeScript - Website: https://garajdas.com - https://muhammetsafak.com/portfolio/garajdas/ - Markdown: https://muhammetsafak.com/portfolio/garajdas.md #### Qurandia - 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. - Role: Founder & Developer - Class: Side Publications - Tier: Active Development - Status: Ongoing - Started: 2026-09-23 - Technologies: Laravel, PHP, Livewire, Alpine.js, Tailwind, PostgreSQL, Redis, Horizon, Filament, Pest - Website: https://qurandia.com - https://muhammetsafak.com/portfolio/qurandia/ - Markdown: https://muhammetsafak.com/portfolio/qurandia.md #### Parantaj - A personal and corporate financial management platform.

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. - Role: Designer & Developer - Class: Older / Hobby Projects - Tier: On Demand - Status: Ongoing - Started: 2026-09-13 - Technologies: TypeScript, Next.js, React, React Native, Expo, Vitest, MDX, IndexedDB, CSS Modules - Website: https://regnarium.com - https://muhammetsafak.com/portfolio/regnarium/ - Markdown: https://muhammetsafak.com/portfolio/regnarium.md #### sakinkal - 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. - Role: Founder & Editor - Class: Side Publications - Tier: On Demand - Status: Ongoing - Started: 2026-05-30 - Technologies: Astro, Tailwind CSS, TypeScript, Markdown, Pagefind, Cloudflare Pages - Website: https://sakinkal.com - https://muhammetsafak.com/portfolio/sakinkal/ - Markdown: https://muhammetsafak.com/portfolio/sakinkal.md #### TB1MSK - 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.' - Role: Operator & Developer - Class: Side Publications - Tier: On Demand - Status: Ongoing - Started: 2026-03-20 - Technologies: Astro, TypeScript, Markdown, Cloudflare Pages - Website: https://tb1msk.com - https://muhammetsafak.com/portfolio/tb1msk/ - Markdown: https://muhammetsafak.com/portfolio/tb1msk.md ### Minimal Maintenance Receives security and compatibility fixes only. #### InitPHP - 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. - Role: Founder & Developer - Class: Older / Hobby Projects - Tier: Minimal Maintenance - Status: Ongoing - Started: 2022-08-12 - Technologies: Composer, Git, PHPUnit, PHP - Website: https://initphp.org - Source code: https://github.com/InitPHP - https://muhammetsafak.com/portfolio/initphp/ - Markdown: https://muhammetsafak.com/portfolio/initphp.md #### Looplio - Looplio — a recurring automation platform (Web + iOS + Android) that turns repeating tasks, maintenance, and checks into reusable templates and automatically generated checklists. - Role: Owner - Class: SaaS Products - Tier: Minimal Maintenance - Status: Ongoing - Started: 2023-01-01 - Technologies: PHP, Laravel, Go, PostgreSQL, Redis, Expo, React Native, iOS, Android - Website: https://getlooplio.com - https://muhammetsafak.com/portfolio/looplio/ - Markdown: https://muhammetsafak.com/portfolio/looplio.md #### SilkWard - 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.
