API & Backend Development
“A backend designed for maintenance, observability, and growth.”
We design and build the backend systems your product runs on. REST and GraphQL APIs, database architecture, authentication, third-party integrations, webhook systems, and background job queues.
We write code that's clean, documented, and ready for your team to maintain.
Start with a focused first build.
Send the workflow, the tools involved, and where the handoff breaks. We will map the smallest build that can prove value before you commit to a larger system.
The useful parts of this build.
These are the pieces buyers usually need when the workflow has to run inside a real product, CRM, dashboard, or internal operation.
Clean API layer for product screens, mobile apps, and integrations
Database structure built around real business records and reporting
Permission checks for users, teams, tenants, and admin actions
Reliable third-party connections with retries and webhook verification
Background jobs for imports, exports, notifications, and AI tasks
How this moves from audit to production.
The first version stays narrow enough to ship, but includes the architecture, integrations, model layer, review path, and observability needed by a real team.
Design resource models, API contracts, auth scopes, rate limits, webhook events, and service boundaries before coding endpoints.
Implement Node.js or Python FastAPI services with database migrations, typed validation, structured errors, and OpenAPI documentation.
Add queues for long-running jobs, third-party API retries, webhook delivery, AI tasks, and scheduled maintenance work.
Secure the backend with token rotation, permission middleware, tenant-aware queries, audit trails, and integration secrets management.
Load test key endpoints, tune indexes, measure queue latency, and document deployment and rollback procedures.
Questions before building this workflow.
Do you build REST, GraphQL, or both?
We choose the contract based on the product. REST is often best for integrations and public APIs, while GraphQL can fit complex dashboard views and client-driven data loading.
Can the backend be split into microservices?
Yes, when the domain needs it. We separate services around clear ownership such as billing, ingestion, AI jobs, notifications, and reporting instead of splitting prematurely.
How do you make third-party integrations reliable?
We use idempotent handlers, retry queues, webhook verification, alerting, and replay tooling so API outages or rate limits do not corrupt product state.
