Experience
Configstore
https://github.com/caravancoop/configstoreConfigstore is a Python module meant to be used with Django that allows it to store configuration items in different back-end environments (environment variables, Docker secrets, dotenv file, AWS SSM, etc.).
Contributed to the Linux Kernel
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.19-rc2&id=e3cb78c772de593afa720687ce3abbed8d93b0c3Contributed a bug fix to the Linux kernel. This fixed a bug where using 802.1Q VLANs on certain hardware would completely corrupt the packets it was sending. I had to dig deep into the kernel code to determine what was happening.
Added Support for IT8688 to Open Hardware Monitor
https://github.com/openhardwaremonitor/openhardwaremonitor/pull/1157I added support for the IT8688 chip to Open Hardware Monitor by reverse-engineering the official Gigabyte utility for hardware monitoring. This project involved reverse-engineering a C# application and debugging it with symbols exported from JetBrains dotPeek to Visual Studio 2017.
