Services
SaaS from 0 to 1
From concept to first paying customer. I build the whole product — auth, billing, admin area, deployment — not just the demo version.
Currently taking on new projects
The starting point
The real effort sits between a working demo and a product you’d trust with real customer data and real payments: tenant isolation, billing, access rights, an admin area, a deployment that doesn’t interrupt the service on every release. That’s exactly where small teams and solo founders need the most support.
How I approach it
-
Product architecture first: design the data model and tenant isolation so it grows with real customers.
-
Plan the payment provider and billing from the start, not bolted on afterwards.
-
Zero-downtime deployment and monitoring from release one, so the first paying customer isn’t the first outage risk.
What you get
- A complete product instead of a demo — including auth, billing, and an admin area.
- An architecture that survives the jump from first test users to real paying customers without a rebuild.
- A deployment process that allows releases without downtime from day one in production.
