Case studies from a decade building secure, accessible public services.
MyCareer.NJ — New Jersey's statewide career platform
A prototype became public infrastructure 1.7 million residents now rely on. Getting there meant the test coverage, security, and accessibility a statewide service has to have.
A proof-of-concept AI career coach grounded in real state data
MyCareer.NJ is live for 1.7 million residents, and the shared AI safety infrastructure runs in production. The coach itself is still a proof of concept, waiting on a state pilot. No resident has used it. It was built so it can't invent a program, a price, or a promise. A review of all 50 states turned up no equivalent resident-facing conversational coach grounded in real program data.
Engineering a CMS Medicaid data portfolio
A 53-person engineering organization behind more than $100M in federal contracts. It includes a CMS Medicaid data-collection portfolio her teams own, and a specialization in health-data interoperability.
Growing an engineering org, and keeping it whole through turbulence
An engineering organization grew from 39 to 53 people. The harder part: it stayed intact and kept delivering through company-wide change, run on a trust-based, trauma-informed model.
Data infrastructure for California's energy and climate system
At the California Energy Commission, Chelsea designed and shipped the data systems the state uses to track petroleum, fuels, and energy. That reporting feeds California's energy-demand forecasts. She also helped move the agency to the cloud.
Public-safety systems for California's caregivers and care facilities
As a software engineer at the California Department of Social Services, Chelsea built and ran systems that families and the state lean on: a public registry of more than 170,000 caregivers, background-check tooling wired to DOJ and FBI records, and a PCI-DSS payment portal for more than 140,000 licensed facilities.
Shipping open data to standard: CTDL credentials and FHIR health data
The delivery work behind open, portable public data. Chelsea operationalized CTDL credential publishing for New Jersey, and she leads Coforma's FHIR specialization for CMS Medicaid systems.
