Want to build an autonomous AI Agentic workflow or a production SaaS that actually scales past a simple prototype? I am a Top Rated Plus Full-Stack AI & SaaS Developer specializing in production-ready Next.js applications, robust LangGraph multi-agent systems, and secure Stripe monetization. I don't build basic ChatGPT wrappers—I engineer self-correcting multi-agent systems, advanced Retrieval-Augmented Generation (RAG) pipelines, and monetize them using scalable web frameworks. With a 95% Job Success Score and over $20,000+ earned across 30+ successful Upwork contracts, my primary focus is delivering exceptionally clean, maintainable code straight into your GitHub repository. Agentic AI & Intelligent Workflows • Multi-Agent Systems: Building production-grade autonomous teams using LangGraph, LangChain, and Python for complex task routing. • Advanced RAG Pipelines: Architecting high-recall contextual search engines utilizing semantic chunking and vector databases (PostgreSQL/Supabase). • AI Voice & Automation: Designing low-latency voice agents and backend automation using Retell AI, Vapi, and n8n pipelines. Production SaaS Delivery • Next.js & Supabase: Crafting secure customer portals, state-driven dashboards from Figma, and bulletproof user authentication. • Stripe Revenue Operations: Flawless deployment of Stripe subscription tiers, usage-based billing, checkouts, and reliable webhook handlers. • Backend Infrastructure: Optimizing FastAPI and Node.js microservices deployed natively on Google Cloud Run or AWS. Core Technical Stack: Next.js, React, TypeScript, Python, FastAPI, Supabase, PostgreSQL, Stripe, OpenAI, Anthropic Claude, LangGraph, Retell AI, n8n, and Google Cloud Run. Send over your current codebase, project specification, or product roadmap. I will review it, identify your biggest technical risk, and propose a practical first milestone to get us moving immediately.
