Service
Full Stack
Overview
Most of the expensive failures in a digital product happen between the parts, not inside them. The interface assumes a field the API never returns, the architecture cannot carry the load the business plans for, or the payment integration works right up until a settlement fails and nobody knows what state the order is in.
Working across the full stack removes the seam. The data model, the services, the integration contracts and the reconciliation path are decided together and by the same people, so the questions that usually fall between vendors get answered before they cost anything.
Capabilities
What full stack covers
Backend & API Integration
Services and APIs built around your domain, and connected to the systems you already run — with authentication, authorisation, audit logging and explicit handling for the day a third party is down.
System Architecture
The data model, service boundaries and trust boundaries decided and written down before the build, sized for the load you actually expect rather than the load a diagram implies.
Payment & Fintech Integrations
Payment, collection and disbursement flows integrated end to end — idempotent requests, verified callbacks, and a reconciliation path so every transaction has a known final state.
Process
How we deliver it
The four stages full stack moves through, and what you have at the end of each.
Model the system
The domain, the data and the integration points mapped together, so the architecture is a decision with reasons attached rather than a default.
Contracts before code
API contracts, error cases and the money-handling rules agreed in writing first — these are the things that are expensive to change later.
Build through the stack
Each increment delivered from interface to service to integration, so what you review is a working path rather than a layer waiting on another layer.
Prove it settles
Failure and retry paths exercised deliberately, reconciliation demonstrated against real cases, then documentation and handover to your team.
Copy pending founder sign-off
PRD §8 requires the exact scope of each service to be confirmed before final copy. Outstanding for this one:
- Which payment providers and rails are supported as standard — card processors, mobile money, bank transfer — and in which markets
- Whether any regulatory or PCI DSS scope commitments can be stated publicly for payment work
- Standard support terms for payment integrations after handover, given settlement issues are time-sensitive
