I build production AI SaaS — not demos. Cut a client's OpenAI costs 80% and token usage 70% on a live lead-gen pipeline serving real paying customers. Full-stack engineer with 3+ years shipping AI-powered SaaS products end-to-end: Python/Django on the backend, React/Next.js on the front, and OpenAI/LLM integration in between. Top-rated on Upwork with 100% Job Success across 46 jobs. Most clients come to me with one of these problems: 🔹 "We want AI in our product but don't know where to start." I've built LLM features that hold up under production load — AI lead scoring, company-fit assessment against ICPs, data enrichment pipelines. I also make them cheap to run. On my current product I consolidated 5 separate GPT-4o-mini calls into a single JSON-mode request and pruned unused profile fields, dropping API costs 80% and tokens 70% with no loss in output quality. 🔹 "We need a real SaaS, with billing and multiple customers." Multi-tenant architecture is my specialty. I've architected hierarchical tenancy (agencies → branches → users) with 6-role RBAC, TOTP 2FA, soft-delete across all models, and subscription-gating middleware. Stripe subscriptions and credit billing, webhook sync, httpOnly-cookie JWT auth — wired up properly, not bolted on. 🔹 "Our scraping/automation pipeline keeps breaking." I built a custom DB-backed priority queue with thread-pool workers, deduplication, and crash recovery to orchestrate a multi-stage LinkedIn scraping + AI enrichment pipeline. Also fluent in n8n, Make, Apify, Selenium, and Celery/Redis for scheduled work. 🔹 "We need the frontend to actually feel good." React 19, Next.js 14, TypeScript, Tailwind, shadcn/ui, Zustand, TanStack Query. I've shipped a Retool-style nested AND/OR filter builder, drag-and-drop Kanban CRM pipelines, and fully bilingual English/Arabic interfaces with proper RTL support. Stack: Python · Django · Django REST Framework · Celery · Redis · PostgreSQL/Neon · React · Next.js · TypeScript · OpenAI API · Stripe · Docker · AWS · Azure · GitHub Actions CI/CD · C#/.NET How I work: I own projects end-to-end — system design, REST API architecture, deployment, CI/CD, monitoring. You get clear communication, honest timelines, and code that a future developer can read. My longest-running client (2+ years) hired me for reliability and kept me for it. You'll find a live, production AI SaaS product in my portfolio below — worth two minutes if you want to see how I actually build. If you're building something AI-powered, need a SaaS built properly from the start, or have a half-finished project that needs someone to take it over the line — send me a message with what you're working on and I'll tell you honestly whether I'm the right fit.
