Hey, I'm Mabud.

I build AI native systems. Agents, data ingestion pipelines, and everything around them. From the RAG architecture to the backend API to the mobile app that puts it in a user's hands.

My main focus is AI Native Systems. Building agents, multi-agent systems, RAG pipelines, and LLM-powered products that actually hold up in production. I have worked with LangChain, LangGraph, PydanticAI, OpenRouter, GraphRAG, vector stores like Milvus and Qdrant, and graph databases like Neo4j.

On the backend I reach for FastAPI and Go. On the frontend it is Next.js, Svelte, or Flutter depending on what the product needs. I do not pick a side. I pick whatever ships the best product fastest.

Currently a Software Engineer at FeatsClub, one of the first hires, working across the full stack. Before that I shipped projects for clients across the world through Fiverr and Upwork, which taught me how to move fast and communicate clearly.
