Backend Development

Strategy, implementation, launch, and support with one connected technical team.
What This Service Solves
Identifying the hurdles
Frontend work gets the attention, but backend problems are what actually break products. An API that doesn't handle errors gracefully, a database schema designed around one use case that can't accommodate the next one, authentication that wasn't built with roles in mind from the start — these are the issues that cause rewrites six months after launch.
- API endpoints with no error handling or inconsistent response formats
- Database schema that doesn't scale as the product grows
- Authentication that doesn't support multiple roles or organisations
- No documentation for how the backend works or how to extend it
Our approach & solution
We design the database schema and API structure before writing a line of code, discuss trade-offs upfront, and build with extension in mind. Every endpoint is documented, every integration is tested with real credentials, and the codebase is handed over with enough context for any developer to pick it up.
- Database design reviewed before implementation begins
- REST or GraphQL APIs with consistent error handling and versioning
- Role-based authentication with JWT or session management
- Full API documentation in Postman or OpenAPI format
What This Service Includes
API Development
API Development
REST and GraphQL APIs with consistent endpoint design, proper error codes, rate limiting, and versioning so breaking changes don
Database Development
Database Development
Schema design for relational databases like PostgreSQL or MySQL, including indexes, foreign keys, and migration paths for schema changes.
Authentication Systems
Authentication Systems
User registration, login, session management, JWT tokens, OAuth integrations, and role-based access control built to scale across user types.
Payment Gateway Integration
Payment Gateway Integration
Stripe, PayPal, or Braintree integration for one-time payments, subscriptions, invoicing, and webhook handling for payment events.
Third-Party Integrations
Third-Party Integrations
Connections to CRMs, ERPs, logistics platforms, email providers, and communication tools via REST APIs and webhook handlers.
Server-Side Rendering
Server-Side Rendering
Next.js server-side logic, API routes, and middleware for applications that need data fetched at request time rather than in the browser.
How Businesses Use This
Real-world applications across industries — drag or click the cards to explore.
Multi-Tenant API for a Subscription Platform
An API supporting multiple customer organisations, each with their own users and data, with JWT authentication and plan-based feature flags.
Business Outcomes You Can Expect
Error Handling That Makes Sense
APIs return consistent error codes and messages so the frontend can handle failures gracefully without parsing unpredictable responses.
Codebase You Own
You receive the full repository with no runtime fees or vendor lock-in. The code runs on your infrastructure.
Role-Based Access Built In
Authentication and permissions are built to support multiple user types from the start rather than bolted on after the fact.
Tested Integrations
Third-party integrations like payment gateways and CRMs are tested with real credentials and edge cases before the code reaches production.
Documented APIs
Every endpoint is documented in Postman or OpenAPI format so your team or future developers know exactly how to interact with the backend without guessing.
Schema Designed Before Build
The database structure is agreed on before implementation starts, avoiding the expensive rework that comes from schema changes after data is already in production.
Questions Before We Start
A Few Things Clients Usually Ask
Find answers to common questions about Backend Development solutions, setup procedures, scoping timelines, and deliverables.
What database should we use for our project?
For most web applications PostgreSQL is a solid default. It handles relational data, JSON fields, and scales well. If your data is genuinely document-oriented or you need flexible schemas, MongoDB is worth considering. We discuss the trade-offs during scoping so the choice is based on your actual data structure and query patterns.
Do you build both the frontend and backend, or just one?
We can do either. Many projects start with just the backend API and connect it to an existing or separately built frontend. Others are full-stack builds. We scope each project based on what you actually need.
How do you handle environment secrets and credentials?
We use environment variables managed through your deployment platform and never commit secrets to the repository. We provide a documented list of required environment variables for each deployment environment.
What happens if we need to change the database schema after launch?
We set up database migration tooling as part of every backend project so schema changes can be applied and rolled back in a controlled way without manual SQL on the production server.
