I build software that makes complex work simpler.

Applications, data pipelines, and the infrastructure that runs them, from the first query to production.

Selected work

Four systems, four different roles.

From sole architect to contributor, each system lists the role I held on it.

RecurringDataFeeds

Automated reporting and claims feeds.

I designed and built RDF with Python and Prefect 3 on Kubernetes to replace a legacy SSIS package and consolidate a SAS reporting estate. Its claims feeds handle claim routing, reversal logic, AUS work-item queueing, and downstream persistence.

What it replaced

SSIS sequence containers: 60+
SSIS SQL tasks: 300+
SSIS data flows: 120+
SAS reports: 380+

With one Python and Prefect 3 platform on Kubernetes, across SQL Server, Oracle, MongoDB, Databricks, Db2/Cosmos, and S3.

Annual recurring savings: Six figures
Projected claim-payout impact: $3M+
