Built recoverable submission ingestion, validation, and versioned SQL persistence for a flexibility reporting platform using Python and Azure Functions. Delivered a React/TypeScript administration app with Entra ID authentication, Terraform infrastructure, and automated deployments. Used AI-assisted development with persistent task context and integration tests, applying human review across application, database, and infrastructure repositories.

Worked across HQ payments and fiscalization teams spanning five AWS accounts. Designed fulfilment-node automation with colleagues and handed it over for implementation, saving an estimated 40 engineering hours per week by eliminating recurring support tickets. Improved stability and security with RDS Proxy across multiple databases, dedicated service accounts, and OpenTelemetry tracing to diagnose a live issue. Led payment-link delivery in Go with Adyen and implemented cash rounding. Modernised build and development workflows across Go and Python services, and contributed to fiscalization and e-invoicing RFP analysis to define target architecture for checkout, reconciliation, and provider routing. Helped stabilise the platform ahead of peak trading with no major incidents after prior outage history.
