Backend API Development Services

We build backend APIs that stay maintainable as your product grows—clean service boundaries, robust auth, and data workflows designed for production reliability.

Overview

What this service is

This service covers backend API delivery end-to-end: requirements to data model, endpoint implementation, authentication/authorisation, and deployment-ready setup.

We focus on predictable contracts—validation, error handling, and documented endpoints—so frontend teams and integrations can build without constant breakage.

You receive source code, practical API documentation, and a structure that supports new endpoints and features without turning into a monolith.

Benefits

What you get

Stable API contracts for faster frontend work

Clear request/response shapes and validation reduce integration churn and rework.

Security-minded auth and permissions

Session safety, access control, and pragmatic guardrails built into core flows.

A data model built for change

Schema decisions that support new features and reporting without constant migrations pain.

Reliability and observability baseline

Logging, error surfaces, and monitoring hooks so production issues are diagnosable.

Performance foundations

Sensible indexing, query patterns, and caching options where they matter.

Clean handoff for long-term ownership

Docs and notes so your team can maintain and extend the backend after delivery.

Features

What we deliver

API architecture + project setup

A scalable structure for routes, services, data access, and shared utilities with conventions your team can follow.

Endpoints + business logic

Well-scoped endpoints with clear business rules, status handling, and predictable behaviour.

Authentication + authorisation

Role-aware access patterns, token/session handling, and secure boundaries aligned to your product roles.

Database design + migrations

Schema modelling, indexes, and migration workflow so data changes stay controlled.

Validation + error handling

Input validation, consistent error formats, and defensive programming for safer integrations.

Documentation + deployment guidance

API docs (OpenAPI where applicable), environment setup, and deployment notes for production readiness.

Process

How we work

1
3–5 days

Discovery

We confirm endpoint scope, roles, and success criteria—then define a milestone plan.

2
3–6 days

Data model

We map entities, relationships, and constraints so the database supports your workflows cleanly.

3
2–6 weeks

Build

We implement endpoints and services with validation, auth, and consistent error behaviour.

4
3–7 days

QA

We test critical workflows, edge cases, and integration behaviours to reduce production surprises.

5
2–4 days

Deploy + Handoff

We deliver documentation and deployment notes so your team can operate and extend the backend.

Use Cases

Who this is for

Mobile app backend

Auth, user profiles, and core endpoints designed for mobile latency and reliability needs.

SaaS product APIs

Role-aware endpoints, tenant-safe patterns, and workflow APIs ready for dashboards and billing.

Third-party integration layer

A clean backend that connects multiple services (CRM, payments, automation) with predictable contracts.

Webhook processing service

Idempotent webhook handlers, retries, and event logging so integrations don’t silently fail.

Admin and reporting backend

Operational endpoints for exports, filters, and analytics workflows that teams use daily.

FAQ

Frequently asked questions

Yes. We can implement APIs on Firebase/Supabase or build a Node backend with PostgreSQL—based on your product and team constraints.

Yes. Auth and access control are common requirements, and we build them into the foundation so you don’t bolt them on later.

Yes. We provide practical docs (OpenAPI where applicable) plus notes about key workflows and integration assumptions.

Yes. We build connectors with validation, retries, and clear failure behaviour for external APIs.

Yes. We use production-minded patterns for validation, logging, and deployment so the backend can operate reliably.
