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.Wed, 23 Sep 2026 00:00:00 GMTpublicationLaravelPHPLivewireBladeTailwindPostgreSQLRedisFilamentPesthttps://muhammetsafak.com/portfolio/devrazzi/https://muhammetsafak.com/portfolio/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.

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%.

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.
