Ali B.
AI App Developer | LLM Agents, RAG & Chatbots | Full-Stack Engineer
I build AI features that hold up in production: agents, RAG systems over private documents, and LLM integrations wired into real applications with auth, queues, evals, and error handling. Top Rated with 100% Job Success across 990 hours on Upwork. Most people who can call an OpenAI endpoint can't ship the system around it. I can. Five years of full-stack work plus Rust and Go backends means the streaming, concurrency, cost control, and vector search parts don't fall over when you get real traffic. WHAT I BUILD AI agents and automations — multi-step agents using OpenAI, Claude, and open models, with tool calling, retries, and human-in-the-loop review where it matters. RAG and document search — chatbots and search over your internal docs, contracts, or knowledge base. Chunking, embeddings, reranking, and evals so answers are actually accurate. LLM features inside existing apps — adding AI to a product you already run, without rewriting it or blowing up your inference bill. High-performance backends — Rust, Go, Node.js, NestJS. Kafka, Redis, Postgres, MongoDB. Where latency and concurrency are the problem. Full-stack delivery — SvelteKit, Next.js, React, Tailwind, deployed on AWS Lambda, Azure Functions, or Firebase. One person, front to back. Tools: OpenAI API, Anthropic Claude API, LangChain, vector databases, Rust, Go, TypeScript, Node.js, NestJS, SvelteKit, Next.js, React, Postgres, MongoDB, Prisma, Drizzle, Kafka, Redis, Playwright, Jest. Send me a message with what you're trying to build and I'll tell you honestly whether AI is the right tool for it.
