The engine room your product runs on.
APIs, databases and the systems behind them, built in Go and Node.js. We design backends that stay fast under load, keep data safe and make the next feature easy to add.
- Well-documented APIs
- Designed to scale
- Secure by default
- Monitored in production
What we build.
Backend development from Quru Lab: APIs, databases and microservices in Go and Node.js, designed to stay fast, secure and reliable as your product grows across Nigeria and beyond.
API development
REST and GraphQL APIs with clear contracts and documentation, ready for your web and mobile apps.
Database design
Data models that match how your business works, with the indexes and backups to keep them healthy.
Microservices
Services split along real business lines, so teams ship independently and failures stay contained.
Payments and integrations
Payment gateways, SMS, email and third-party systems, connected reliably with retries and audit trails.
Background jobs and queues
Scheduled tasks, notifications and long-running work moved off the request path so the app stays quick.
Performance and scaling
Profiling, caching and query tuning for backends that have started to slow down as usage grows.
From first call to launch, and after.
The same process we use on our own products, so you always know what happens next.
- Step 1
Model
We map your data, users and rules, and agree the API contract before anything is built.
- Step 2
Architect
We choose the services, storage and hosting that fit your scale today and the next stage of growth.
- Step 3
Build and test
We develop in short cycles with automated tests, so every endpoint is checked before it ships.
- Step 4
Run and improve
We deploy with monitoring and alerts, then tune performance as real traffic arrives.
Tools we trust.
We pick the stack that suits your product, team and budget, not the other way round.

Questions about backend development.
Straight answers before you get in touch.
Mostly Go and Node.js. Go suits high-traffic services that need to be fast and efficient; Node.js suits teams that want one language across frontend and backend. We recommend based on your product and team.
Yes. We can audit what you have, fix performance and reliability issues, add features or gradually move parts of it to a better structure without stopping the business.
Yes. We design APIs around your product, not one screen, so the same backend can serve your website, mobile apps and partner integrations.
Authentication and permissions on every endpoint, encrypted connections, validated inputs, careful handling of secrets and regular dependency updates. Security is part of the build, not an add-on.
