Hey, I’m Daniyal Ahmed. I’m a Full-Stack Engineer based in Lisbon with 3+ years of experience. I currently work at ZappyRent.
I build and ship end-to-end products across Next.js and Node.js, plus modern GenAI stacks like RAG, LangChain, and LangGraph. I also build voice agents with LiveKit for real-time calling and conversations. I focus on practical agent workflows with strong retrieval, clear tool contracts, evaluation, guardrails, and observability.
