Senior AI Engineer with 12+ years of experience building multi-agent AI systems, RAG pipelines, workflow automation, and full-stack SaaS platforms using LangChain, CrewAI, n8n, and OpenAI, delivering scalable, production-ready solutions from architecture to deployment. I personally lead every engagement, backed by a vetted team for when projects need to scale. Across 36 Upwork contracts (with 100% Job Success Score) and 300+ projects throughout my career at AllZone, Fieldforce, Allshore, and AAJ Technologies, I've built systems that ship on time and hold up in production. What I build: → Multi-agent AI systems - LangChain, CrewAI, AutoGen, RAG pipelines, and LLM-powered workflows built for production → Automation infrastructure - n8n, Make, Zapier, and custom integrations that eliminate manual bottlenecks → SaaS backends & APIs - Node.js, .NET, REST/GraphQL, Stripe, and complex third-party integrations → Full-stack web apps - MERN, Next.js, PHP, Laravel, with scalable cloud architecture on AWS and Azure Recent work: → Architected a CrewAI multi-agent system for a patent-pending fintech platform, 330+ hours, 5-star review → Rescued a stalled .NET + Stripe + Persona + Twilio build after the original developer quit, delivered on deadline in 500+ hours, and again, a 5-star review → Built an AI-powered FDA Label Compliance System, automated a regulatory review process that previously required hours of manual work For projects that need dedicated full-stack depth, standalone MERN builds, .NET enterprise systems, or PHP/Laravel backends, my team handles those end-to-end with the same standards and ownership model. Who I work best with: Founders and technical leads who want a senior engineer that communicates clearly, moves fast, and takes full ownership from architecture to delivery. Let’s connect and build something exceptional!
