100% audit-finding closure in a single quarter — inside an active patient-portal modernization.

An anonymized deep-dive on a multi-state Health Information Exchange that needed a modernization partner accountable to its compliance, not just its roadmap.

The challenge

A 14-hospital HIE was running a .NET monolith patient portal written in 2011. Three concurrent compliance audits — HIPAA, SOC 2 Type II, and an internal clinical-risk review — had surfaced 38 findings, 11 of them classified as high-severity. The internal team of 22 engineers was already 18 months behind the modernization roadmap and could not absorb a parallel remediation track without burning out.

The CIO needed a partner that could ship and close audit findings on the same calendar — not one after the other.

The approach

  • Two-week sprint co-development with the internal team via shared Slack, Jira, and a weekly Friday live-demo. No black-box offshore delivery.
  • Strangler-fig migration off the monolith behind a single API gateway, so cutover could happen per-hospital-system without a big-bang release.
  • Compliance-first engineering: every PR required an evidence trail (threat model diff, test artifact, audit-log entry) before merge. Findings were tracked as Jira epics, not Confluence pages.
  • Velocity Framework™ baselines applied to the first 6 sprints — reducing time-to-first-deployment from an internal baseline of 24 weeks to 9 weeks.
