Sensely (285k Users): Built an AI-driven healthcare engagement platform powered by conversational AI and NLP. An avatar-based virtual nurse assesses symptoms, guides patients to the right care, and delivers personalized health recommendations, fully integrated with healthcare systems and insurance services on secure, scalable infrastructure trusted by hospitals. TECHNICAL STACK AND SKILLS Languages: Python (FastAPI, Django, Flask), JavaScript/TypeScript (Node.js, NestJS, React, Next.js). AI Orchestration: FastMCP, LangGraph, LangChain, AutoGen, CrewAI, OpenAI, Claude. RAG. Vector Databases: Pinecone, Qdrant, ChromaDB, pgvector. Automation: n8n, Zapier, Make, Celery, Docker. Voice AI: Retell AI, Vapi, ElevenLabs, Deepgram, Twilio. Security: NVIDIA NeMo Guardrails, kernel-level sandboxing, data sovereignty reviews. Reliability: DeepEval, Braintrust, Evaluation-Driven Development (EDD). HOW I ENGINEER AI SYSTEMS I design modular, scalable agents around your exact workflows, not generic templates. Every system is built to integrate cleanly with your CRM, ERP, and SaaS stack and engineered to keep delivering value long after launch. Every project starts with a clear technical specification defining features, functions, and interactions upfront. You get predictable delivery, transparent communication, and zero surprises during development. If you’re aiming to elevate your AI projects into production-grade solutions, let’s collaborate. Send your project details, and I’ll provide insights and a roadmap within hours.
