Message

At Black and Yellow (Blink Suite), I engineered a multilingual headless CMS with dynamic content management, CRM modules, and a configurable dashboard. I also built a NestJS modular monolith with MongoDB, using event-driven patterns and API rate limiting.

At Attraxia, I implemented a RAG system connecting OpenAI’s GPT model, Pinecone, and PostgreSQL for semantic knowledge-base search, alongside a document-processing pipeline. I’ve also developed backend fintech features at Factory Digitale and built products including Tripnest, a real estate rental platform for the Algerian market.
