About

Builder. Seller. Shipper.

I'm a startup-minded AI Solutions Engineer and technical founder with hands-on experience architecting, selling, and deploying LLM-powered applications using Claude, OpenAI APIs, and Python/Django backends.

I built Voicely end-to-end using Claude Code — from LLM architecture and evaluation frameworks to API orchestration, zero to production.

Through Somnium Labs, I run consultative AI sales cycles, closing and delivering Voice AI and LLM solutions for business clients. I combine deep builder credibility with technical sales experience to help founders and engineering teams move fast and ship with confidence.
