Selected story
Counterfact turns API contracts into controllable, stateful simulated systems—so product teams and agents can keep building when real dependencies are unavailable or unstable.
Principal Engineer · Developer Experience & Platform Architecture
Fix the system,
not the symptom.
I improve engineering productivity by building the technical and operating foundations that remove friction from how software gets made.
One career, viewed through selected systems changed.Choose a row to focus the story.
| Role & period | System constraint | What I changed | Evidence of outcome | Technical / operating proof |
|---|---|---|---|---|
| Independent developer Counterfact2022–present |
Front-end and agent-assisted work waits on unavailable APIs, cloud access, or shared environments. | Built and maintain a local-first API simulation tool that turns OpenAPI specifications into controllable, stateful simulated APIs. | Developers can implement and test success, failure, rate-limit, and stateful scenarios without production access. | TypeScript · Node.js · OpenAPI Deterministic scenarios, tests, CI, public docs, release automation. |
| Walgreens2021–2026 | Fragmented UI foundations, opaque technology ownership, and disconnected enablement work slowed delivery. | Progressed from hands-on frontend architecture to enterprise architecture and delivery-system leadership. | A lean team delivered an offline-first kiosk application in about two months; executives regained confidence in a reset engagement. | Web Components · TypeScript · Git + CI/CD Shared backlog, technology catalog, pull-request-based updates. |
| Software Engineering Manager / Advisory Engineer Jack Henry2018–2021 |
Treasury UI modernization risked a disruptive rewrite and fragile customer-specific variants. | Built the UI team's Omega framework and reusable foundations, separating business rules from presentation. | Supported incremental AngularJS-to-Web Components modernization and roughly 90% faster development for new screens. | Web Components · Design system · Monorepo Mob programming, CI/CD, team formation. |
| Advanced Software Engineer Siemens PLM Software2017–2018 |
Testing maturity was difficult to compare across a distributed microservice landscape. | Created a shared assessment of coverage, pass rates, and CI-gate status across more than 20 repositories. | Gave leadership and teams a common view of testing discipline and gaps without formal authority. | Java · JavaScript · C# · Python · Scala Test automation, quality signals, collaborative review standards. |
