Backend Development & API Integration
Reliable systems, integrations and APIs behind the interface.
The right fit
Start with the work it needs to do.
The backend is responsible for the information and rules that an interface depends on. We build services and APIs that connect web or mobile products to their data and to the tools a business already uses. Clear contracts between systems matter as much as the screens users see.
An interface can look complete while its data flow remains fragile. Requests may fail, records may be duplicated and integrations may behave differently under real conditions. Backend work addresses how data is validated, stored, accessed and exchanged, including the cases where another service is unavailable.
Our approach
Clear decisions before implementation.
We define API contracts around the tasks the product needs to support, then review validation, access rules and database relationships. Third-party connections are designed with their actual constraints in mind. Important flows include useful error responses and sensible handling of retries, so a failed connection does not silently create inconsistent work.
Capabilities and technology choices
Our backend toolkit includes Node.js, Express, MongoDB, MySQL and REST APIs. Existing capabilities include payment connections and services such as Paystack, Firebase and Cloudinary where appropriate. These are tools for specific requirements, not a requirement to introduce a new dependency into every system.
Delivery
A practical path through the work.
Build explicit contracts
Implement the agreed endpoints, validation and integration behaviour alongside the consuming interface.
Verify failure paths
Check successful and unsuccessful requests, permissions and deployment needs, then document the interfaces needed for ongoing work.

Questions worth resolving early.
Can you connect an existing frontend to a new API?
Yes. We review what the frontend expects and agree the contract before implementation. Changes on either side are included in scope.
Can you integrate a payment provider?
Payment connections are part of our capabilities. The flow and provider requirements must be reviewed, including confirmations and unsuccessful transactions.
Will you replace our database?
Only if the requirements justify it. Existing schema, data quality and migration constraints inform the recommendation.
