* Proposed, prototyped, contributed to design and delivery of a system to transform 15 years of medical records into an interoperable format. Pipeline processes 500M changes across 100M patients daily using Hadoop streaming hosted on AWS.

* Led transformation for historical medication records, collating data from prescriptions, refills, manual entries on medication list using Node.js.

* Explored creation of a unified medical record for each patient, consolidating data across the athenahealth network.

* Built query analysis and regression tooling to enable safe migration from Perl monolith

to microservice architecture.

* Defined models for clinical data, allowing movement and reconciliation between practices. Designed and implemented automated test framework to ensure correctness of

relocated data.

* Built workflows for entry of millions of orders daily (e.g., prescriptions, lab requisitions).

* Delivered features critical to patient-safety, including medication dosage calculation.

* Incorporated and advocated for engineering best-practices such as dark-launches, schema migrations, and optimistic saving.
