Saad Ahmed S.

Most AI SaaS MVPs stall in month three — not from bad ideas, but from architecture that can't scale past the first 100 users. I’m an AI SaaS developer specializing in MVP development for startups, building scalable products with Next.js, Node.js, and Supabase, and integrating OpenAI and AI agents into real-world applications. 14 years in, 11,450+ hours on Upwork, $300K+ delivered — and a 100% Job Success Score across every one of those contracts. What I actually do: I build multi-tenant SaaS platforms with Next.js (App Router), Node.js, and Supabase — and I integrate OpenAI, Claude, and AI agents in ways that create real automation, not demo-ware. Most of my work lands in one of three buckets: AI SaaS MVPs — launch in 6–10 weeks with clean auth, Stripe billing, multi-tenant data isolation, and a working OpenAI/LangChain integration from day one AI integration into existing products — add RAG, vector search (Pinecone / Supabase Vector), or agent workflows to a platform that already has traction SaaS rescue & scale work — taking over codebases where the original team overbuilt, and getting the product to a place where it can actually handle load Stack I ship with: Frontend: Next.js, React, TypeScript, Tailwind, shadcn/ui Backend: Node.js, REST/GraphQL APIs, Supabase Edge Functions Database: PostgreSQL (with RLS for multi-tenancy), Supabase, MongoDB AI: OpenAI API, Vercel AI SDK, LangChain, vector DBs, RAG pipelines Infra: AWS (EC2, RDS), Vercel, Docker, nginx — I manage production infrastructure serving 160+ domains, so "it works on my machine" isn't a phrase I use Recent work: → Multi-tenant CRM with automated lead pipelines and AI-assisted lead scoring — handles thousands of users, tens of thousands of daily requests → AI-powered marketing funnel builder (React + Next.js) with real-time analytics → Real-time data dashboards with D3.js for an ocean/fisheries prediction platform → Migrated a production SaaS across 179 domains with zero downtime after a security incident How I work: I think in terms of business outcomes before I open an editor. I'll tell you when a feature you asked for is the wrong one and what to build instead. I communicate in writing, keep PRs small, and show a working demo every week. No black-box development. Who I'm a fit for: Funded startups and scaling SaaS companies that need a senior engineer who can own the technical side of a product without a PM holding their hand. European (especially DACH region) and US clients make up most of my work. Who I'm not a fit for: Projects that need the lowest bidder, or founders who want code without conversation. Both of us will save time if we skip that call. Next step: Send me your product brief, current stack, or the bottleneck you're trying to get past. I'll reply within a few hours with an honest read on whether I can help, what it would take, and a clear timeline.
