15+ years turning ideas into businesses that grow, as one person who gives your project everything. No agency, no handovers, and you own everything I build. I build the tech, read the data and run the marketing as one measurable loop, so growth compounds instead of leaking between three suppliers who never talk.

The reference page every formula on this site links to. Percentages, averages, spread, probability, tests, regression, elasticity, compounding and lifetime value, each from scratch with one shop's numbers worked through.
A handful of decisions in the first month of a SaaS decide what the next ten years cost. How to keep one customer's data apart from another's in Rails, where the tenant lives in the code, Postgres row level security, users in several companies, tenant versus billing account, and why the isolation model is also your GDPR strategy.

Every shop owner wants to know what the competition charges, and every one asks the same question first: are we allowed to? A plain language map of the rules in the UK, the EU, Germany and Austria: why prices are facts, where the database right reaches, what the Ryanair cases decided, where logins and blocks draw the line, text and data mining, GDPR, and the competition law trap nobody mentions.
What headless actually means, when it is worth it and when it is not, the one application hybrid I build on Solidus, what the Solidus 4.8 API gives you today, what you still design yourself, and what the app stores charge a shop.
