One of my clients just closed $1M in seed funding on a SaaS platform I built. Another is running a live AI agent inside medical practices, fully HIPAA compliant. I am a Full Stack AI Engineer with 8 years of experience and 20+ AI and SaaS products shipped. If that is what you need, keep reading. Most AI projects fail between the demo and production. The agent works in a sandbox, the RAG pipeline pulls wrong context in the real environment, and the SaaS MVP that looked perfect in staging cannot handle actual users. That gap is what I close. IBM and Meta certified |Top Rated. FinTech, MedTech, and EdTech. Here is what I build and what it actually does for your business: AI Agents and Multi-Agent Systems using LangGraph, LangChain, and CrewAI that execute real business workflows so your team stops doing manually what a system should handle automatically. 2. RAG systems that stop your AI from giving wrong answers to paying customers. Hybrid retrieval, re-ranking, and evaluation pipelines built on Pinecone, pgvector, and ChromaDB. 3. SaaS MVPs and multi-tenant SaaS platforms with auth, Stripe billing, role-based access, and admin dashboards that go live in weeks, not quarters. 4. AI workflow automation connecting n8n, Make, and Zapier to LLM backends that permanently replace manual processes across your operations 5. Production deployments on AWS, GCP, and Supabase with Docker, CI/CD, and observability built in from day one, not patched in after something breaks. Two products I shipped recently: Dandalee is a procurement SaaS platform for the Architecture, Engineering, and Construction industry. Built end-to-end on Next.js, Express.js, and n8n automation. It onboarded 2,000+ sellers, closed a $50K bridge round, and secured $1M in seed funding in Q1. Doclatch is a HIPAA-compliant AI healthcare assistant built on LangChain and FastAPI. It parses unstructured medical documents, extracts clinical context, and generates structured staff task cards with source-level citations so every AI output is liability-proof for the practice. Stack: AI & LLM: OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, MCP, Function Calling, Model Routing, AI Agents, Multi-Agent Systems, AI Copilots RAG & Search: RAG, Embeddings, Semantic Search, Pinecone, pgvector, ChromaDB, Document AI, OCR Automation & Reliability: n8n, Make, Workflow Automation, Human-in-the-Loop Systems, Evaluation Frameworks, Hallucination Reduction Frontend: Next.js, React, TypeScript, Tailwind CSS Backend: Python, FastAPI, Django, Node.js, NestJS, REST APIs, GraphQL, WebSockets Databases: PostgreSQL, Supabase, Redis, MongoDB SaaS: Multi-Tenant Architecture, Tenant Isolation, RBAC, Admin Dashboards, Stripe Billing Cloud & DevOps: AWS, Docker, Vercel, CI/CD, Monitoring Security: OAuth2, JWT Authentication, Encryption, Audit Logs Voice AI: Vapi, Retell AI, ElevenLabs, Deepgram, OpenAI Realtime API, Twilio Integrations: Stripe, Plaid, Open Banking APIs, QuickBooks, Xero, CRM Integrations, ERP Integrations If you are building an AI agent, RAG system, SaaS MVP, or full stack AI product and need it to work in production, message me with what you are trying to build. I will tell you in the first reply whether it is feasible, what the architecture looks like, and roughly what it costs. No sales call needed to get a real answer.
