Servers & interfaces
Backend development: what runs behind your application
Serverpod backends: data models, interfaces, authentication with roles and permissions, deployment, monitoring. Fixed price per written scope, weekly deliverable states, handover with repository and documentation.
Fixed price per written scope (€60/h equivalent)
I build backends with Serverpod — the open-source server framework for Dart: data models, interfaces, authentication with roles and permissions, deployment, monitoring. Fixed price per written scope, weekly deliverable states, handover with repository and documentation.
When this fits#
- Alongside an app or web application: app development and web development need data storage — built from one hand, in one language, without a translation layer.
- As maintenance of an existing system: you have a Serverpod backend and need extensions, migrations or an infrastructure refresh.
- As interface work: your system needs to talk to another one — import, export, webhooks, file exchange.
What a Serverpod backend brings#
- Type-safe interfaces: client and server share the models in Dart. A field change breaks at build time, not in production.
- Authentication with roles: users, permissions, admin areas — by convention instead of hand-built sessions.
- PostgreSQL with migrations: versioned schemas, traceable changes, seed data for test environments.
- Caching, tasks, logging: background jobs and scheduled tasks are part of the framework, not a side system.
- Operational readiness: deployment with Docker, TLS, a backup strategy and monitoring are part of my delivery, not an add-on.
What I don't offer#
"Getting it running somehow" without documentation; a fixed-price guarantee without a scope sheet; taking over foreign code without a joint assessment — I will tell you openly beforehand whether entering an existing codebase is worth it.
The process#
Stepwise scope, fixed price, weekly intermediate states, written acceptance, handover: the mechanism is described on /en/prozess and is the same for every offer. For the pricing logic: /en/preise.
After acceptance#
Build-out for further changes (€480/day), maintenance & operations (€240/month) for operation, updates and monitoring — or handover to your own team. The code is yours, runnable without me.
