The challenge

Why it mattered

PNOĒ combines breath-based metabolic testing with software for health, fitness and longevity professionals: dashboards, client apps, treatment planning and business tools. Practitioners around the world need to publish availability, accept bookings and run sessions across time zones — and every part of the platform depends on fast, reliable backend services underneath.

What we built

Capabilities delivered

Backend architecture · API engineering · Scheduling & availability · Integrations · Long-term team augmentation

01

Scheduling system

End-to-end booking flows for practitioners and clients — creation, rescheduling, cancellation and notifications.

02

Availability engine

A dedicated availability model with recurring rules, exceptions and buffers that resolves bookable slots in real time.

03

Time-zone correctness

Availability and bookings that stay correct across time zones and daylight-saving changes worldwide.

04

Core backend services

A large part of the platform’s backend: domain services, data models and the APIs consumed by web and mobile clients.

05

Integrations

Services that connect the platform with external systems, devices and data sources.

06

Reliability & performance

Background processing, validation and monitoring so the platform stays fast as usage grows.

Engineering highlights

How we built it

  • .NET
  • C#
  • PostgreSQL
  • REST APIs
  • Cloud infrastructure
  • Background jobs
  • Time-zone aware scheduling
  • Domain-driven availabilityAvailability modelled as a first-class entity — not just free gaps in a calendar — so complex rules stay maintainable.
  • Conflict-free bookingServer-side validation prevents double bookings and race conditions under concurrent load.
  • API-firstClean, documented APIs that serve dashboards, client apps and partner integrations alike.
  • Embedded collaborationOur engineers work inside PNOĒ’s product team, roadmap and release process.
Outcome

The scheduling system and availability engine are core to how PNOĒ practitioners and their clients work every day. The partnership continues, with CodeSoft engineers contributing across the platform’s backend.
