About

I've spent my career building products end to end, from writing the code to running the company.

I'm currently a hands-on engineering lead at Wand: I lead the backend team and still write a lot of the code myself. Before that, at SolarReviews, I grew from engineer to Head of Engineering & COO. I architected the marketplace behind the company's growth, built its internal CRM and lead-qualification systems, and introduced A/B testing and ad automation across Google and Meta.

I'm also the co-founder and sole engineer of Booking-Bot. After years in lead generation, I saw how many leads were lost to slow follow-ups and missed calls. So I built a platform that uses AI voice and SMS agents to engage every lead and put confirmed appointments on contractors' calendars.

I work AI-first, which makes me stack-agnostic. I'd rather spend my time on architecture and on the environments and feedback loops that let agents do real work than on the syntax of any one language.
