Custom Software
Custom software, SaaS products and internal platforms engineered to scale.
API & system integration
Systems that share data reliably
We design and build APIs and integrations so your systems stay in sync, partners can connect to you, and nobody has to copy data between tools.
The problem
Integration debt
Every disconnected system creates manual work, and every quick integration becomes something nobody understands.
Systems out of sync
Customers, orders and stock differ between tools.
Undocumented scripts
Old integration scripts that only one person understands.
Security gaps
API keys shared in code and no record of who accessed what.
Failures nobody sees
Sync jobs fail quietly and data drifts.
Our approach
Integrations engineered for reliability
We treat integrations as products: designed contracts, retries, monitoring and documentation.
- Clear API contracts and documentation
- Retries, idempotency and dead-letter handling for failed messages
- Secrets management and least-privilege access
- Monitoring and alerts on every integration
- Automation platforms where they fit, custom services where they do not

FAQ
API & System Integration questions
Straight answers to the questions that come up in first calls.
Should we use an automation platform or custom integration code?
Automation platforms such as n8n are ideal for many business workflows. Custom integration services make sense for high volume, strict reliability needs or complex logic. We often combine both.
Can you integrate with a system that has no API?
Often, yes, through database access, file exchange or other approaches, though we will explain the trade-offs first.
Do you document the APIs you build?
Yes. Every API comes with documentation, usually OpenAPI, so your team and partners can use it.
