I build AI systems that survive contact with production. 110+ Upwork projects, $60K+ earned, 100% Job Success, 10 years shipping web applications, the last two focused on production AI. Most AI features die between the demo and the launch. They hallucinate, break on real data, or cost too much to run. My work starts where the demo ends: agents, RAG, and LLM features that are evaluated, observable, and still working months later. I work alone, by choice. No team, no hand-offs. The person you talk to is the person who builds it, tests it, and supports it. What I build: - AI agents and agent workflows: OpenAI and Anthropic APIs, LangChain, MCP, multi-step automation that runs unattended - RAG and LLM features inside your existing product: retrieval pipelines, vector databases, prompt engineering - AI evaluation and reliability: eval harnesses, LLM-as-judge, regression gates in CI, so you know your AI is correct before and after launch - LLM observability: tracing and diagnostics with OpenTelemetry, so you can see what your AI is doing and what it costs - Business automation with AI: lead qualification, support triage, feedback classification, internal tools - WordPress and WooCommerce: custom plugins and AI integrations. Published plugin author in the official WordPress plugin directory, WordPress Core AI Team contributor Proof that runs, not just proof that shipped: - A production AI lead qualification agent system, 1,900+ runs, built and operated for my own business: it scrapes, filters, scores, analyzes with an LLM, and alerts, unattended, every day - Published Python tooling for AI evaluation: evalspec and posthog-llm-doctor on PyPI - An open source AI agent readiness plugin, Mokhai, live in the official WordPress plugin directory - A government authority website in production - 40% of my clients come back for more work A good fit if: - You have an AI feature that works in the demo but not in production - You want AI added to a product or business process that already matters - You can describe the problem and make decisions, and you want a scoped first phase instead of a big-bang promise - You want part-time or retainer help from one accountable senior person Not a fit if: - You need a seat filled in a large sprint team - Your timeline assumes a parallel team (one person ships sequentially) - You are shopping for the cheapest option One more thing: if the AI you are asking for should not be built yet, I will tell you. Saying no to the wrong build is part of the job. Background: pharmacist turned engineer, fully remote from Egypt, fluent in English and Arabic. I run my own business on the AI systems I build. Message me one paragraph about what you are building and where AI fits. You will get a straight answer: what I would build, what I would skip, and whether I am the right person for it.
