AI Integration Engineer building production SaaS. Not demos. I ship live AI features - GPT/Claude integrations, RAG systems, AI-powered workflows - inside real products that customers pay for. 10+ years full-stack, Top Rated, 100% Job Success. My work currently powers platforms serving 10,000+ active users. Recent shipped products (live, in production): - BookBI: AI accounting app for UAE entrepreneurs, live on iOS + Android - FundsVisor: multi-tenant SaaS finance platform with AI receipt scanning - Nucleus AI: GPT + PubMed research tool for clinicians A few results clients hired me for: - Cut payment processing time by 40% by re-architecting Stripe/PayPal integrations for a SaaS platform - Built and shipped production LLM features (OpenAI and Claude APIs): chatbots, document processing, and AI-assisted workflows inside existing products - Migrated 2M+ records from legacy SQL Server to PostgreSQL with zero data loss and under 2 hours of downtime - Reduced regression testing time from 4 hours to 30 minutes with 500+ automated API tests (85% coverage) WHAT I DO BEST 1. AI integration into real products. I connect OpenAI/Claude APIs to your existing app with proper prompt design, streaming, cost controls, hallucination guards, and error handling - so the feature survives production traffic. 2. Full-stack SaaS product delivery. Next.js + TypeScript on the frontend, Node.js (Express/NestJS) or ASP.NET Core (.NET 6+) on the backend. REST and GraphQL, event-driven systems, WebSockets/SignalR. 3. Stripe billing done right. Subscriptions, webhooks, trials, marketplace payouts (Connect), multi-currency. I've shipped Stripe production twice - I write idempotent handlers and treat billing bugs as P0. 4. Cloud and DevOps. AWS (EC2, RDS, Lambda, S3, CloudWatch), Azure, Docker, CI/CD. 5. Databases and migrations. PostgreSQL, SQL Server, MySQL. Schema design, query optimization, high-stakes zero-downtime migrations. I also handle legacy modernization when clients need to move a monolithic or desktop system to a modern cloud stack, without breaking the business that depends on it. HOW I WORK I take ownership: I ask the questions that surface hidden requirements early, break work into clear milestones, write maintainable code with reviews and tests, and communicate proactively. You will never wonder what's happening with your project. Clients describe me as reliable, collaborative, and a clear communicator (their words, from endorsed reviews). A good fit looks like: a SaaS founder or team building AI features into a product, or one that needs a senior engineer who can think about the product, not just the ticket. I'm not the right fit for lowest-bid or rush-only projects. If you need AI capabilities added to your product, production Stripe billing, or a scalable backend built right the first time - send me an invite and let's talk through your project.
