What This Service Covers

The backend is what keeps your product alive under load. We build APIs and backend systems that are fast, observable, and easy for your frontend team to work with — complete with documentation, error handling, and rate limiting from the start.

// how we work

Our Process

01

API Contract Design

We define API contracts before implementation — endpoints, request/response schemas, error codes — so frontend and backend can develop in parallel.

02

Database Modeling

Schema design with normalization, indexing strategy, migration planning, and query optimization baked in from day one.

03

Development & Testing

Every endpoint ships with unit tests, integration tests, and OpenAPI docs. No black boxes.

04

Performance & Security

Load testing, N+1 query elimination, rate limiting, input validation, and auth hardening before anything touches production.

Common Questions

Q.REST vs GraphQL — which should we use?

It depends on your frontend needs. REST is simpler and cacheable; GraphQL shines when clients need flexible queries. We help you pick the right tool.

Q.Can you integrate with third-party services?

Yes — payment gateways, SMS/email providers, shipping APIs, CRMs, ERPs. We've integrated with dozens of Indonesian and global services.

Q.How do you handle API versioning?

We implement versioning from day one (v1, v2 routes or header-based) so you can evolve your API without breaking existing clients.
