Summary

Senior🎓
Top SchoolFabien Chraim is a research and engineering leader and co-founder with 15 years of experience building large-scale networked systems, ML-driven automation, and real-time infrastructure deployed at hyperscale. He led AWS efforts to turn rule-based network operations into model-driven automation using causal and graph-based methods, producing signals and models that became core to availability, root-cause analysis, and multi-million dollar capacity decisions. Earlier, he co-founded Civil Maps to deliver HD mapping and real-time localization for autonomous vehicles, and his hands-on firmware work on OpenWSN shows deep embedded systems chops across radio drivers and low-level hardware initialization. A UC Berkeley PhD, he blends robotics-inspired world models with production engineering—favoring causal inference and continuous-retraining pipelines to enable autonomous decision-making in critical infrastructure. Now based in Sacramento, he’s translating hyperscale operational experience into founding-stage innovation at his stealth startup.

OpenWSN firmware: stuff that runs on a mote
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:35 commits in 10 months
Contributions summary:Fabien primarily focused on modifying firmware for the OpenWSN project. Their contributions involved adding and modifying board-specific files, particularly related to radio drivers and hardware initialization for the Eldorado and Gina platforms. These changes included modifications to header files, SPI drivers, and interrupt handlers. The user also addressed issues with sensor initialization and sleep routines, directly impacting the low-level functionality of the embedded system.
