SaaS & product engineering

SaaS products engineered to grow from the first customer

A SaaS product is more than a web app: tenants, plans, billing, permissions, onboarding, emails, APIs and analytics all have to work together. I build that foundation so you can focus on the feature that makes your product unique.

The architecture starts simple and grows with you — no over-engineering for users you do not have yet.
