Paymax
One platform for delivery, transport, voting and health insurance.
Backend engineer and one of its two largest contributors. I owned four of its domains.

- Duration
- 14 months
- When
- 2025 to 2026
What I did
- Wrote the transport, medical, election and project-management domains, and most of delivery.
- Moved the delivery service into the main application in one change, dropping its Kafka, OPA and Elasticsearch dependencies.
Impact
Owned four of the platform's domains outright and led two more.
When things go wrong
When a service costs more to run than its traffic needs,
the team chose to consolidate; I moved delivery into the main process and dropped its Kafka, OPA and Elasticsearch dependencies.
