As an AI Developer and two-time VC-backed startup contributor, I've spent 8+ years turning complex ideas into products that actually make it to market with RAG pipelines, LLM fine-tuning, AI agents, voice agents, and full-stack SaaS platforms built with LangChain, LlamaIndex, CrewAI, Deepgram, and Pinecone.
My niche? Taking the messy, ambitious stuff from and shipping it as lean, scalable systems.
