Open Source Experience

Open source contributions made to the following projects, among others:

Linux kernel contributor since May 2016. Author and maintainer of intree kernel Perl script scripts/leaking_addresses.pl. Responsible for hashing printk specifier %p, landed in v3.15. Involved in the removal of Variable Length Arrays from the kernel tree, enabling make -Wvla. Worked on layer 2 networking code. Focus on the KS7010 SDIO Wi-Fi driver. PowerPC contributions; while resolving PowerPC kernel issues contributed documentation patches to the GNU Assembler, as well as assembly code. Various other contributions to: device drivers (staging), networking (including wireless), Kernel Self Protection Project, storage, and memory management. 200+ patches merged into the mainline.

While studying data structures and algorithms contributed code, and design test implementation, to the Gonum graph library written in Golang. Utilized graph library as reference while implementing solutions to graph problems on HackerRank.

Contributed to the Free Software Foundation Guile project. Interacted with Guile community via public mailing list. Iterated multiple revisions in order to assimilate a personal fix into a patch that was acceptable by the community. Produced a solution to a known outstanding issue requiring a multi- language patch set in C and Scheme.

Contributed to the OpenBazaar Server project, codebase in Python. First non-company contributor to the project. Most patches were unit testing and code refactoring. Some work on the command line interface and interoperability between operating systems.
