Summary
🤩
Rockstar🎓
Top SchoolSean Kwok is an experienced Oracle DBA based in Centreville, VA, with seven years in database administration and a longer track record in GIS, geospatial analysis, and systems engineering across federal and defense contracts. He combines backend database stewardship at CACI with earlier senior consulting roles at IBM and technical leadership in GIS development for DHS and other agencies, bringing strong domain knowledge in geospatial data and decision-support systems. Sean also contributes to embedded systems and IoT open-source projects—adding board support and example code for M5Stack and ESP32 platforms—showing hands-on hardware integration skills not obvious from his DBA title. He holds a BS in Decision Science & MIS from George Mason and a Masters in IT from Harvard, blending analytical rigor with practical implementation experience.

m5stack/M5-ProductExampleCodes
May 2019 - May 2021
All example codes of products supplied by M5Stack have been collected in this reposity.
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:31 commits, 2 PRs, 24 pushes in 2 years
Contributions summary:Sean contributed example code for various M5Stack product modules, primarily focusing on interfacing with sensors and peripherals commonly used in IoT applications. These contributions included code for reading data from modules like the M5IoT-kit, and various HATs (ToF, Joystick, 8Servos, etc), incorporating sensors, and controlling actuators. The examples demonstrate a focus on hardware interaction and low-level programming to provide basic functionality for different M5Stack products. The user implemented example for data display on the LCD.
