Aziz S.
Full-Stack AI & Design Engineer | AI Agents, Figma, Nextjs, React
Top Rated Full-Stack AI Engineer with 5+ years of experience building production AI agents, RAG systems, and scalable SaaS products using LangGraph, LangChain, Python/FastAPI, Next.js, PostgreSQL, OpenAI API, and Claude API. I build the parts that turn an AI idea into a usable product: the agent or retrieval workflow, APIs, database, interface, integrations, and deployment. I usually work with startups and product teams that need someone who can own the system end to end. My main areas of work include: ā¢ AI agents and multi-agent workflows using LangGraph, LangChain, tool calling, MCP, structured outputs, and memory ā¢ RAG and knowledge systems: document ingestion, embeddings, vector databases, retrieval tuning, citations, and evaluation ā¢ Backend engineering with FastAPI, Django, NestJS, PostgreSQL, Redis, REST APIs, WebSockets, and background processing ā¢ Full-stack AI products using Next.js, React, TypeScript, authentication, payments, and admin dashboards ā¢ Production deployment using Docker, Kubernetes, Azure, GCP, monitoring, and observability Recent work includes an AI-powered ride-sharing and tourism platform, an LLM-based education platform, a RAG semantic-search product, and a pharmaceutical packaging-validation platform. Clients bring me in to build a new AI product, stabilize an existing system, or turn a prototype into reliable production software. I communicate clearly, work independently, and stay focused on the product and business outcome.
