Zain M.
AI Integration & SaaS Developer | OpenAI, Node.js & AWS
You may already have a SaaS product that works and want to add AI without putting the rest of the application at risk. Or you may have an idea for an AI-powered product and need someone who can build the whole thing. I help with both. For existing products, I add OpenAI integrations, AI agents, and custom AI features directly to the current codebase. That means working carefully with the product's existing users, databases, APIs, permissions, and business rules. For new products, I can take care of the full build: architecture, backend, frontend, AI features, and AWS infrastructure. My main stack is Python, FastAPI, Node.js, React, Next.js, PostgreSQL, and AWS. A few examples of my work: • I helped build Griffin, an AI-powered SaaS platform, from an idea into an MVP in about six weeks. The engagement reached 1,078 hours and received 5-star feedback. • I built a product intelligence tool with LangChain and Pinecone that turns a client's own data into useful summaries and insights. • I completed a security and AWS cost overhaul for a live SaaS platform without interrupting its users. I also handle the less visible work that makes an AI product dependable, including error handling, security, performance, deployment, and cloud costs. I bring 10+ years of full-stack engineering experience, $200K+ earned on Upwork, and Top Rated status. If you have an existing SaaS product or an idea for a new one, send me the current stack, the problem you are solving, and what you want AI to do. I will assess the requirements, identify the right implementation path, and tell you exactly where I would start.
