How we approach it

Back-end & APIs

A back end is successful when nobody talks about it. Loads stay flat, jobs run on time, integrations do not silently fail at 2am, and a new developer can read the code six months later.

We design schemas, build REST and GraphQL APIs, wire third-party services and modernise the parts of a legacy system that have become a business risk. Our work spans PHP and Laravel through to Java, Spring Boot, Node.js and Python FastAPI.

You get documentation alongside the code: an endpoint reference, an entity diagram and a short note on every external dependency and what happens when it goes down.

What we deliver

Inside the engagement

A typical scope for this service. Yours will be narrower — that is the point of a written scope.

API design & build

Versioned REST or GraphQL APIs with consistent errors, pagination, rate limits and an OpenAPI reference your team can actually use.

Database modelling

Normalised schemas, sensible indexes and migration history in PostgreSQL or MySQL — plus a backup and restore plan that has been tested.

Authentication & permissions

Role-based access, SSO, token refresh and audit trails, implemented once and reused across web and mobile clients.

Third-party integrations

Payments, WhatsApp, SMS, email, maps, accounting and ERP systems — with retries, logging and graceful failure instead of silent drops.

Background jobs & queues

Scheduled reports, imports and notifications that run reliably without blocking a user's request.

Legacy modernisation

A incremental path off ageing PHP or Java code: strangle the risky parts first, keep the business running throughout.

Proof, not adjectives
