In August 2025, delivered a critical routing fix for the CESA debt endpoints in hmrc/debt-transformation-stub, improving reliability of debt request processing. By adding the '/cesa' prefix to the CESA debt creation and cancellation endpoints, requests now route to the correct controllers, reducing misroutes and potential failures in production. This work is captured in commit ccb081533a50979caa36cb6be865e1f509d18314 (DTD-2527: Corrects CESA endpoint (#339)). Overall impact: higher endpoint accuracy, fewer support incidents, and easier future maintenance of CESA debt flows. Technologies/skills demonstrated: REST endpoint routing, controller wiring, version-controlled fixes, and traceable commits in a HMRC repository.

Summary for 2025-07: Focused on delivering charge information capabilities via the Time To Pay Proxy and strengthening testing coverage for VATC scenarios, while improving security posture through a library upgrade. Key work spanned two repositories, aligning API design, domain modeling, and test-driven delivery to enable faster, compliant customer charge info retrieval and robust testing.

May 2025 monthly summary: Focused on delivering a high-value enhancement to the AffordableQuoteInstalment model in the time-to-pay-proxy, with robust API schema updates and data-type accommodations to support larger values. No critical incidents reported; changes are test-covered and traceable.

April 2025 monthly summary for hmrc/time-to-pay-proxy: Focused on API stability and data-model integrity. Delivered a targeted bug fix to revert the unintended 'expectedPayment' field from the instalment data model in the Affordable Quotes API, removing the field from the data model and related tests. No new features were released this month; instead, the work safeguarded contract integrity and reduced downstream risk in quotes and payment workflows. The changes improve API reliability for quoting scenarios and support safe future evolutions of the proxy by keeping payloads aligned with product contracts. Technologies demonstrated include backend data-model changes, test maintenance, and precise change tracing through commit messages.
