Aziz S.

I design and build AI products end to end, from the interface to the agents, APIs and deployment. If you have an AI idea, a prototype that breaks on real data, or a SaaS that needs AI features that actually work, I can take it to production. I'm a full-stack AI developer and design engineer with 5+ years of experience. Right now I'm a Senior Full-Stack Engineer (AI) at a German AI startup. What makes me different: I design the product and I ship the code. You don't need a separate designer, frontend developer and AI engineer, and nothing gets lost between them. What I build: • AI agents and multi-agent workflows: LangGraph, LangChain, tool calling, MCP, structured outputs, memory • RAG and knowledge assistants: document ingestion, embeddings, vector databases, retrieval tuning, citations, evaluation • AI SaaS products and MVPs: Next.js, React, TypeScript, auth, payments, admin dashboards • Backends: Python/FastAPI, Django, NestJS, PostgreSQL, Redis, WebSockets, background jobs • Product and UI design: clean, usable interfaces designed in-house and built pixel-accurate • Production: Docker, Kubernetes, Azure, GCP, monitoring and observability Recent work: an AI financial research platform (RAG and semantic search), an LLM-based education platform with real-time AI avatars, an AI-powered ride-sharing and tourism platform, and a pharmaceutical packaging-validation platform. What clients say: "Very knowledgeable and very aware of the latest developments in tech. Always quick to create MVPs and refine them as your needs expand." How I work: we start with a short call or a small paid discovery milestone. You get a clear plan, fixed milestones and regular demos. I'm in Tunisia (UTC+1), which overlaps fully with Europe and the morning in the US. I speak English, Arabic and French. Send me a message with what you're building. I usually reply within a few hours.
