Yasser A.

I build RAG systems, LangGraph agents and n8n automations that run in production, not demos. Recent work: → Column Mate, a paid app live on the Monday App Store (App ID 10601212). → An n8n pipeline that cut article production from about 4 hours to under 5 minutes. It publishes to 5 platforms on its own. → A flat-file JSON system moved to Postgres in 9 migrations, with dashboard reads under 100ms p95. What I mostly work on: → Agent systems. LangGraph, custom orchestration and MCP, for things like document analysis pipelines and internal company tools. → RAG. Pinecone or pgvector, tuned for production, not plug-and-play LangChain. → Full AI products. Auth, billing, infra and the AI parts, end to end. Stack: Python, Node.js, FastAPI, PostgreSQL, n8n, OpenAI, Claude, LangChain, LangGraph, MCP, Pinecone, Whisper, ElevenLabs. Top Rated with a 100% job success rate, 30+ jobs and $10K+ earned on Upwork. I work in Arabic and English. Send me what you're trying to build and I'll tell you straight if I can do it, how long it takes and what it costs.
