Case Studies — Recent Client Engagements

Real engagements, written up by the engineer who shipped them.

Every case study below is anonymized but otherwise as-is: architecture decisions, control mappings, code patterns, what shipped, and what we would do differently. No marketing prose. No invented metrics. The same level of detail we give clients during scoping.

Lucas Jones

Founder & Principal Platform Engineer · Sacramento, CA

Every engagement on this page was scoped, designed, built, and handed off by the same engineer who wrote up the case study. Six years across HIPAA, FedRAMP, HITRUST, and SOC 2 environments. No junior consultants billing senior rates.

A note on anonymization

Client names, exact agency identifiers, and specific contract numbers are removed. Architecture decisions, framework choices, control mappings, technical patterns, and outcomes are preserved as-is. If you recognize your engagement and want it taken down, email lucas@stonebridgetechsolutions.com.

CS/01 · AI SaaS · Federal Published

FedRAMP Moderate architecture for an AI SaaS vendor.

A federal customer was ready to procure contingent on a Moderate authorization path with a tight fiscal-year deadline. We architected the AWS GovCloud boundary, federated identity from the existing IdP, codified the boundary in Terraform with policy gates, and wrote control narratives alongside every module.

CS/02 · Healthcare SaaS · HIPAA Published

HIPAA-aligned multi-stage CI/CD pipeline for a healthcare SaaS.

A monolithic GitLab pipeline had become the bottleneck on every deploy and every audit cycle. We decomposed it into parent/child stages, layered Ansible-driven HIPAA control validation across 32+ production hosts, and built audit-ready evidence emission into every deploy. The next audit stopped being a reconstruction project.

CS/03 · AI SaaS · HIPAA · Third Engagement Published

HIPAA CI/CD overhaul for an AI SaaS vendor.

A returning client. Third engagement following the FedRAMP boundary build and the Kubernetes migration. This time the HIPAA-side pipeline was the long pole: unsigned artifact promotion, manual security scanning, and an audit trail that did not survive its own deploys. We rebuilt with Cosign signing, OPA Gatekeeper admission control on EKS, and audit-grade evidence emission inheriting the FedRAMP boundary.

The pattern, documented

Every engagement applies the Evidence-Driven Infrastructure framework.

The case studies above are individual engagements. The underlying methodology is the same across all of them: Boundary First, Continuous Evidence, Policy as Code, Founder-Delivered. The framework synthesizes NIST SP 800-53, FedRAMP 20x KSIs, HITRUST CSF, SLSA, and DevSecOps practice.
