Completed service and network security reviews for a generic data upload service. Designed threat models against abuse and Denial of Service from load testing. Hardened the service's security surface with techniques like endpoint auditing and rate liming.

Made several product contributions to backend services from identified customer pains and needs, like endpoint latency reductions, and FHIR XML data ingestion.

Partnered with the Foundry Slate product team to develop and launch Public Slate Apps, making point-and-click WYIWYG apps accessible to the open internet for data ingestion. Played a full-stack role, owning the implementation of app-publishing security controls, handling unauthenticated HTTPS requests, and re-writing the frontend experience to adapt Slate capabilities to a mode for the open internet.

Built PySpark data pipelines for three NHS trusts to report data from local authorities to the National body. The data was used by directors to decide on resource allocation, rollout tracking, and strategy for a nationwide health program. Owned the design and implementation of the data ingestion and pipelining, but also helped in defining the applications' data model and experience.

Added final user experience features before the rollout of a new approval-orchestration service.

The service acts as the security backbone for numerous collaboration workflows in the Foundry platform, including PR approvals, access requests, ontology changes, etc. (put "Policy Bots" anywhere)

Contributions include reviewer assignment, requests for review, and notifications, all built in Java.

Migrated AUREAN's infrastructure from a dedicated host provider to a mainstream cloud (Azure).

Designed and deployed an initial compute and storage infrastructure aimed at cost-effective MVP prototyping.

Designed the MVP's initial data model and sign up/sign in architectures. Built the system's invitation-based customer onboarding and an OAuth2+OIDC sign in workflow.
