Drive continuous development across the full platform: practitioner-facing interface, backend services, and GCP infrastructure Act as technical reference for architecture decisions, guiding junior engineers through design and implementation Took ownership of a planned data retention system that had significant gaps in sensitive data handling — restructured the database design and implemented an automated retention flow ensuring full GDPR compliance for patient data

Built end-to-end integrations with GitHub App and Snyk to feed a centralised vulnerability analytics pipeline Collaborated on the design and enriched the core vulnerability database, ingesting the full OSV dataset with daily updates Contributed to platform architecture decisions supporting rapid feature delivery and product scalability

Built and owned the core interoperability framework from inception — scaled it to support 30+ microservices across engineering, data, and infrastructure teams, processing hundreds of events per minute per service Navigated a rigorous certification process for government medical document API access, successfully enabling secure patient-data flows. Redesigned the Elasticsearch bulk reindexing pipeline: replaced an unreliable standalone script with a robust, non-blocking process — eliminating manual monitoring and removing performance impact on user-facing APIs Scaled central Java API and SRE tooling, developing CI/CD pipelines and monitoring dashboards, which improved system reliability and performance. Mentored junior engineers continuously throughout tenure as the team scaled from ~30 to ~160 people Led the transition from outdated Java apps to a unified Rails service, which accelerated feature delivery and improved internal tooling.
