Most businesses are sitting on 15–30 hours a week of manual work that custom AI software could handle automatically. I'm an AI Integration Engineer who builds the actual systems — not strategy decks. Custom AI apps, RAG-powered chatbots, n8n automations, and AI-integrated platforms that plug into the tools your team already uses. Top Rated on Upwork with 100% Job Success across 1,300+ hours, working with SaaS teams, law firms, lenders, and agencies who need it shipped right the first time. WHAT I BUILD FOR CLIENTS → Custom AI Software & Apps Full-stack AI applications built from scratch — frontend (Next.js / React), backend (FastAPI / Python), AI logic (OpenAI, Claude, RAG with pgvector or Pinecone), production deployment (GCP / AWS, Docker, CI/CD, Sentry). Recent build: a bilingual Arabic/English legal management platform with a RAG document drafter and WhatsApp client bot — drafting time cut from hours to minutes. → AI Integration Into Existing Software Connecting AI to the tools your business already runs on — CRMs, databases, internal apps, customer-facing platforms. Recent build: an AI underwriting engine for a real estate lender that replaced manual document review across the entire loan lifecycle. → n8n Workflow Automations Self-running pipelines that connect your CRM, email, WhatsApp, databases, and AI models into one system. Recent build: a multi-agent content pipeline that turns a single Telegram command into a published SEO article in 3–4 minutes — replacing ~15 hrs/week of manual work. → RAG-Powered Chatbots & AI Assistants Custom chatbots with real document grounding, conversation memory, and human handoff. Web, WhatsApp, Slack — wherever your customers are. WHY CLIENTS HIRE ME OVER THE NEXT FREELANCER ✓ Top Rated, 100% Job Success, 1,300+ hours on Upwork in this exact lane ✓ Production deployments — not prototypes. CI/CD, monitoring, Docker, GCP/AWS — the boring infrastructure that keeps systems running at 3 AM ✓ Full-stack — I ship the AI logic and the software it lives inside (FastAPI, Next.js, Python, React) ✓ Member of two Top Rated Upwork agencies with 13,000+ combined hours delivered INDUSTRIES I'VE BUILT FOR Legal Tech · Fintech / Lending · Healthcare · EdTech · Content Operations · SaaS Tools HOW I WORK I scope tightly, ship in milestones, and send Loom walkthroughs of every build so you can follow along without needing a technical translator. I respond inside 4 hours and keep you updated even on days nothing ships. IF YOU'RE EVALUATING ME FOR A PROJECT Send me a short message describing what you want to build or automate, and what "done" looks like. I'll tell you honestly whether I'm the right fit, roughly what it'll cost, and roughly how long it'll take — usually inside a day. If it's a fit, you'll get a clear scope, a fixed timeline, and code you actually own.
