The system, step by step
In this case study, we cover the build of a minimum viable product for a wellbeing app. The client had designed the system in an architecture document and needed it working in n8n with SMS and voice.

What the brief demanded
The first phase was scoped deliberately, which shaped the build:
The client
The client was based in the US and had designed the system in an architecture document. The aim was a version that showed every planned feature working end to end.
- Turning an architecture document into running workflows.
- Adding SMS and voice as ways for users to interact.
- Delivering every discussed feature in phase one, while leaving compliance, security hardening and scalability for a later phase.
Built and handed over
We built the MVP as a set of n8n workflows covering all the features in the architecture document, with SMS and voice integration.
- The full phase-one feature set from the architecture document.
- SMS and voice integration.
- A complete n8n workflow package handed over to the client.
The project ran in two milestones, a short setup and the main MVP phase, from late September to October 2025. The workflow package was delivered at the end of October. The client rated the work five stars and endorsed it as Clear Communicator and Detail Oriented.
