Most technical projects work perfectly in a demo and fail miserably in production. They break on messy data, hallucinate without guardrails, collapse under API rate limits, or become impossible to scale. I do not build toys or basic Zaps. I architect production-grade AI systems, custom middleware, and full-stack applications that run reliably when real users and real revenue are on the line. With over $40,000 in verified earnings, a 100% Job Success Score, and Top Rated status, I specialize in moving complex infrastructure out of the prototype phase and into your core operations. PILLAR 1: AI AGENTS & RAG SYSTEMS Autonomous Workflows: Building multi-step reasoning engines (LangGraph, CrewAI) that qualify leads, process documents, and run structured decisions with deterministic logging and retry logic. Production RAG: Architecting document-grounded knowledge bases (Pinecone, LlamaIndex, pgvector) built for private data, strict permission handling, and zero-hallucination source attribution. Voice AI: Deploying inbound/outbound voice agents (Vapi, Retell, ElevenLabs) integrated directly with CRM workflows for real-time lead scoring. PILLAR 2: CUSTOM AUTOMATION & MIDDLEWARE API Orchestration: Replacing fragile, low-code automations with hardened custom middleware and robust workflow pipelines (n8n, Make, Python FastAPI). Failure Management: Engineering webhooks and REST API integrations with circuit-breakers, automated retry logic, and comprehensive error handling. PILLAR 3: FULL-STACK ARCHITECTURE High-Performance Interfaces: Developing the admin portals, interactive dashboards, and client-facing interfaces required to control these backend systems using Next.js, React, and TypeScript. Scalable Infrastructure: Deploying secure, scalable databases and server environments utilizing PostgreSQL, Node.js, and AWS. MY ENGINEERING APPROACH: I map your data sources, isolate the failure points, and build the architecture required for secure, high-concurrency execution. I prioritize fallback logic, strict prompt versioning, and clean handoff documentation so your internal team is never left in the dark. If you need an architecture that scales beyond a proof-of-concept, send me a message, and we can map out the technical scope on a brief discovery call.
