Hi, I am JY

Jo-Yao Hsu (JY Hsu)

Sr. Software Firmware Engineer at Dell Technologies.

Hi there! 👋
I am an active Software / Firmware / Full-Stack / DevSecOps / SDET Engineer and Open-Source Maintainer / Contributor, who love learning new things, solving problems, sharing technical skills and constantly improving myself.

At my current role, I’ve developed a systematic BIOS serial save feature (D4D), reducing engineers’ debugging time and enhancing customer satisfaction and retention. I’m a staunch advocate for CI/CD automated BIOS code signing, release file creation and cutting-edge auto-testing systems, ensuring our releases are bug-free and lightning-fast.

As a Technical Leader, I’ve led diverse teams in delivering major webGIS and software projects such as test automation framework, intergration systems, satellite RADAR data analysis, and urban planning systems.

Outside of my day-to-day work, I hold an AWS Certified Solutions Architect certification, with a focus on cloud computing exploration. I actively contribute to open-source projects and engage with the developer community through tech meetups and conferences. I am committed to continuous learning of new technologies and methodologies to remain at the forefront of software firmware engineering trends.

I also expertise in Geomatics, providing free consulting services and fostering discussions on spatial data. Currently collaborating long-term with a GIS development team.
