Client work · System integrations

System integrations, backend, and APIs that must work reliably under real load

We design backend, APIs, and integrations for digital products and business operations: payments, CRM, ERP, SaaS tools, webhooks, admin panels, and business logic that cannot afford lost data or broken operational flow.

Our own products connect to payments, push notifications, and external APIs in production every day, so we know what an integration needs to survive real traffic.

API and business logic

Stable endpoints, business rules, roles, permissions, and flows that need to work predictably for the product and the team.

Payments and external systems

Integrations with payment providers, CRM, ERP, SaaS tools, and external services that affect sales or operations.

Data flow, retries, and resilience

Webhooks, queues, synchronization, retries, monitoring, and failure scenarios without operational chaos.

1. Contract and edge cases

We define data, source-of-truth rules, system responsibilities, and edge cases before writing code.

2. Implementation for real traffic

We build the integration with error logging, retries, idempotency, and safe failure scenarios.

3. Monitoring and maintenance

We add critical alerts and adapt the integration when external systems or the business process change.

What a well-built integration should feel like

The team stops manually guarding the process. Payments go through, data remains consistent, and exceptions are visible instead of hidden in logs.

Questions

Do we need to integrate everything at once?

No. The safest path is to start with one critical flow, then expand into the next areas.

What is the most common integration mistake?

Not defining the source of truth and what should happen on duplicate requests, timeouts, or partial writes.

Can older ERP or CRM systems still be integrated well?

Often yes, not always through a perfect API, but via an intermediate layer, queues, or a well-designed integration contract.

Need systems that finally talk to each other properly?

Tell us which tools are involved and what should work after launch. We will suggest a safe starting scope.
