Backend & Integrations
CRM integrations
Developing modules that connect an internal CRM to external services: payment systems, email marketing, and analytics, where predictable and reliable data exchange matters.

Context
The project's challenge and context
The team needed a working integration layer between its internal CRM and external services so processes would not depend on manual synchronization and disconnected workflows.
Challenge
What needed to be solved
- Make data exchange clear and manageable instead of a collection of fragile, isolated integrations.
- Handle webhooks, statuses, and retries so the system remains predictable for the team.
- Fit integrations into the existing product environment without unnecessary operational overhead.
Constraints
- External services follow different rules and do not always provide equally useful feedback.
- The team needs visibility: what was sent, what came back, where a failure occurred, and what to do next.
- Integration layer errors quickly become business problems unless resilience is designed in from the start.
Implementation
What was done
I designed an integration layer between the CRM and external systems around clear data exchange points.
I built webhook event processing, queues, and retry workflows for unreliable responses from external services.
I prepared internal observability mechanisms so the team could understand integration health without manual investigation.
I kept the architecture simple enough to maintain and develop without uncontrolled growth in complexity.
Role and stack
My role
Backend and integration ownership: data exchange architecture, module implementation, workflow resilience, and preparation for further development.
Stack
Outcome
What it brought to the business and team
The team gained a more predictable data exchange environment between the CRM and external services.
Integration workflows became easier to diagnose and less dependent on manual monitoring.
A foundation emerged for adding new connections without steadily increasing chaos.
