About Me

I specialize in distributed systems, cloud infrastructure, and systems performance. My research interests include privacy-preserving healthcare systems, federated learning for clinical applications, and medical AI diagnostics.

I act as a technical owner and decision-maker for complex initiatives, leading zero-to-one efforts and guiding cross-functional teams. I balance hands-on system design and implementation with mentorship, stakeholder alignment, and delivery of durable, production-grade solutions.

I serve as Associate Editor for IEEE Internet of Things Journal and npj Digital Medicine (Nature Portfolio). My published work spans federated learning, medical imaging, IoT security, and cloud systems.

Open Source Contributions
NVIDIA
NVFlare — framework for training AI models across hospitals without sharing patient data
  • Found and fixed a bug that was silently producing worse AI models during training. The error went unnoticed because the system ran without crashing, but the results were degraded on every run.
  • Improved the efficiency of the federated learning examples by caching AI models and datasets between training rounds instead of reloading them each time.
  • Fixed a bug where simulation mode always ran one training epoch regardless of configuration, causing simulated devices to behave differently from real devices when multiple epochs were configured.
  • Fixed a stack overflow crash in the Android SDK that occurred during federated training when the device had to retry fetching work from the server many times in a row.
Grafana Labs
Grafana — widely used data monitoring dashboard (65,000+ GitHub stars)
  • Added a color palette designed for colorblind users, so that charts and graphs are readable by people with color vision deficiency.
  • Added an accessible line style option that automatically assigns distinct dash patterns (solid, dash, dot, etc.) to each series, so overlapping lines remain distinguishable without relying on color alone.
  • Fixed a layout issue in the admin interface where data tables had inconsistent column sizing, making them harder to read.
Microsoft
VS Code — the most widely used code editor
  • Fixed how the editor resolves references between style files, so that developers no longer need to write long file paths when importing shared design code.
Prometheus
Open-source monitoring system (57,000+ GitHub stars)
  • Built a page in the web interface that lets administrators delete outdated monitoring data, which previously required writing manual commands.
Expedia Group
Bull — internal data transformation library
  • Fixed a long-standing bug that caused the system to crash when converting data between different internal formats, affecting downstream services that relied on this library.
U.S. Department of Health and Human Services
Simpler Grants — next-generation grants.gov website
  • Fixed a bug where “page not found” errors were incorrectly reported as successful pages, which misled search engines and monitoring tools.
National Institute of Standards and Technology
OSCAL — machine-readable security and compliance framework used across U.S. federal agencies
  • Added a rules-language attribute to parameter constraint tests, enabling tools to automatically validate that security control parameters meet machine-executable constraints instead of requiring manual review.
U.S. Web Design System
USWDS — the official design system used by federal government websites
  • Fixed a console error that occurred when users selected an option from a browser-native datalist autocomplete on text inputs, caused by the component's keyboard handler receiving a non-keyboard event.
Huly Platform
Open-source project management tool
  • Added spell-checking to the text editor used across the platform.
Italian Government
Design React Kit — Italy's official React component library for public administration websites
  • Added versioned documentation deployment to GitHub Pages so each release gets its own URL and the latest version is always accessible.
