building a general MacOS AI Agent, backed by a16z speedrun I joined pre-product, and built the entire LLM agentic system, including: - in-house browser use (did beat browser-use.com accuracy on internal testing! thanks to a novel technique I developed leveraging code generation) - computer use (CUA) - MCPs clients and servers - memory / retrieval systems also mentored 2 junior engineers! :)

building an AI UGC Ads generation product, $1M annual revenue per employee! I built: - emotion control for Arcads AI actors -> led to Arcads most viral feature launch of 2025 (on linkedin) - v1 of the video editing LLM agent - the entire data infrastructure of the company I also started building the AI team (by sourcing, interviewing, and hiring our 2nd AI Engineer)! :)
