Been there

Building the platform's event-driven microservices, running across several regions under heavy concurrency.

Led the modernization of the backend services behind the seat map page of a major airline's booking funnel. Planned the team's work so architectural improvements and new features could land side by side, and mentored other engineers through pair and mob programming.

Owned testing, CI/CD and cloud infrastructure for the team's system, moving it to Azure with Terraform and plugging it into the company's single sign-on over OpenID Connect. With the pipelines in place the team deployed twice a day on average, with no downtime and under ten minutes from commit to production.

Designed and built the account confirmation and password reset flows for the identity services, moved the legacy users across and put a proper test suite around one of the core services. Beyond the team's work, contributed to the company's core libraries for messaging, the transactional outbox and tracing, and interviewed candidates for mid and senior roles.

Full-stack work on the accounts payable product, adding payment methods such as pivot accounts and XML transfer files, and leading the design of the payment proof documents in several languages. Pushed for test-driven development, code quality and CI/CD in the team's day to day.

Worked on the crew management systems, implementing flight time limitation rules and activity assignment for rostering, and speeding up the daily flight duty hours calculation with dynamic programming. Made the read models more reliable too, adding a heartbeat to the event processor so projections stopped missing events.
