App integrations that work in production.
Most app projects are not blocked by screens — they are blocked at integration. Payments that double-charge, notifications that never arrive, APIs that disagree about field names. These pages cover how each one is actually built.

The integration layer decides whether the product ships
A Flutter app is a client. Almost everything users care about — paying, signing in, watching, being notified — runs through a third party. Each integration has its own authentication, failure modes, webhooks and edge cases, and each one can hold a launch on its own.
I integrate these services regularly on mobile, TV and web clients, with the backend work that makes them reliable rather than demo-ready.
Pick the integration you are dealing with.
Each page explains the flow, the failure cases and what production-ready means.
