Mercy I.
Full-Stack Developer | AI Agents, SaaS MVPs & CRM Automation
Need a developer who can build your SaaS and the AI agents that run inside it? I build both, end to end, and you own the code. AI AGENTS AND AUTOMATION I build AI agents that take over a business job: they qualify and answer leads, book appointments, update your CRM and hand off to a person when needed. I also build chatbots for WhatsApp or your website that answer from your own documents (RAG), and workflow automation with n8n connected to your CRM, calendar, email and APIs. FULL-STACK DEVELOPMENT As a full-stack developer I work in Next.js, React and Node.js with Supabase, from login and payments to deployment and handover. I build SaaS MVPs, web apps, dashboards and customer portals, and I fix and finish apps that stalled before launch. WHAT I CAN HELP WITH * Build your SaaS, MVP or web app * Build an AI agent for lead qualification and CRM automation * Build an AI chatbot or RAG assistant for support * Connect your tools: CRM, calendar, email, WhatsApp and APIs * Review, fix and launch an existing app or prototype * Add an AI feature to a product you already have HOW I WORK You send your idea, links and deadline. I reply with questions and a clear scope, and you see working progress every week. You get clean, secure, production-ready code, testing, documentation and support after launch. Not sure where to start? Message me what you want to automate or build, and I will tell you what is realistic and what to do first.
