Four products I own as Product Manager. Each starts with the problem, then the decision and what it cost.
See all workAll-in-one team management SaaS replacing Hubstaff, BambooHR and DocuSign. I sequenced it (time tracking first, then HR and e-signature), and it's now live with 900+ companies and 25,000+ users.
Product Manager on an AI platform for proposals, agreements and invoices. I owned the billing and document journey, wrote and tested the prompts, and defined how AI output is evaluated.
Rooftop Saunas asked for booking software that could one day be sold to other businesses. I owned how it became a platform (which features every operator shares and which each operator sets up) and designed the pricing model, approved by the client: a free marketplace listing that brings in new operators, plus booking software priced by the revenue each operator manages. Launched August 2025; now live with 17 UK operators.
Turned a one-sentence brief into the full product spec for a platform that sells kids' ministry resources to churches, schools, homeschools and families. Live in 12 weeks; $1M+ annual revenue today.

Solves: an AI product that costs too much to run, gives wrong answers, or users don’t trust.
For founders building an AI product.
The scope, user flows and a clickable prototype, plus where the AI acts, what stays on fixed rules, a 20‑example test set and the cost per AI task.
