HillHub
Backend counsel for mobile products that must hold under load.
We advise product and engineering leads on mobile application backends, API contracts, and the integrations that keep releases predictable.
What we take on
HillHub Developer Consulting works with teams shipping mobile apps who need clear advice on server-side architecture, partner APIs, and the handoffs between app, backend, and third-party systems.

Consultations
Practical advisory work — not a product catalogue.
View scope
API contract review
A focused review of the contracts between your mobile clients and backend — versioning, error shapes, and breaking-change risk before a major release.
Integration risk audit
A structured look at the partner APIs, webhooks, and batch jobs that sit behind your mobile product — where failure modes hide and how to watch them.
03
How an engagement opens
We start with your release calendar, current API map, and the integration points that create the most risk. From there we shape a written advisory plan — usually over one to three working sessions — before any deeper retainer begins.

From recent clients
They walked our payments webhook failures line by line and left us with a retry policy we could defend to the board — not a slide deck of buzzwords.
Mara K., product lead, fintech app
The first session felt dense; we had to dig through legacy auth tokens we had avoided naming. After that, the integration map finally matched what production was doing.

Field notes
When a mobile release waits on a webhook
How to decide whether a partner callback is ready for a consumer-facing date — before marketing locks the calendar.
Error shapes that spare mobile engineers
Inconsistent error envelopes across backend services create ghost bugs in QA. Here is a contract habit that reduces that noise.
Auth handoffs between app and backend
Token refresh, silent re-auth, and partner identity brokers — the places mobile sessions quietly unravel.
