My two areas of deepest experience are applied AI (LLM chat and agents,retrieval-augmented search, document AI and OCR, using OpenAI and Anthropic) and third-party API integration (payments, SMS and email, CRMs like HubSpot, GoHighLevel and Close, banking via Plaid, and more). If your product needs to talk to another system, or add an AI feature that actually works in production, that is my home turf.
