A price discovery platform for ETL brokers for one of the major security brokerage firms. As the CTO and co-founder, I designed and developed Eblotter using React and Redux on a Ruby on Rails API, with PostgreSQL as the data store.

Universal Ctags
A project that aims to continue the development of Exuberant Ctags (e-ctags)—the ancestor of Universal Ctags (u-ctags) maintained by Darren Hiebert.

E-ctags improved traditional ctags with multi-language support, enabling users to define new languages searched by regular expressions (called Optlib in u-ctags) and generate Emacs-style TAGS files. Unfortunately, the project's activity stalled.

I initially created a personal fork of e-ctags on GitHub. As interest and participation grew, we moved the development to a dedicated project for u-ctags. This project aims to maintain a common or unified working space where people interested in improving ctags can collaborate. Some of the major features of u-ctags include:

• Increased numbers for language support
• A new extended C/C++ language parser
• A fully extended Optlib – a feature to define a new language parser from a command line

Linux | EDKII | EFI | KVM | Qemu

• Fixed initialization of SATA devices.
• Added several protocols and fixes to the open-source UEFI bootloader and Qemu to unmodified macOS to boot in Qemu.
• Added an implementation of an HFS+ filesystem driver to EDKII.
• Created custom Linux boot images to migrate VMware ESXi to Linux.

MPlayer | FFmpeg

A free and open-source media player software application. I executed AltiVec CPU optimizations in the FFmpeg Swscaler and implemented savage graphics for the VIDIX driver. I also implemented an NSV demuxer, added seeking in Real files without an index, and created the first Musepack decoding patch.

Spca5xx Generic Linux Camera Driver

• Ported Spca5xx to Kernel 2.6.

Embedded Linux and Android Work

• Created Yocto-embedded Linux images for an iMX6 platform.
• Built custom Android images for home video and Mako-based CyanogenMod devices.

Go FreeNAS API Client
• Wrote a Go FreeNAS API client for use with the Terraform provider that I created.

FreeNAS Terraform Provider
• Created a Terraform FreeNAS provider to manage the NAS from Terraform, making it much nicer and easier to use in production environments.

Satellite Communication Simulator

Adding layer 2 to a niche network simulator to simulate layer 2 behavior for Inmarsat satellites. This allowed simulating communication for flight data record person-to-person transfers in Inmarsat zones to estimate the optimal data transfer between planes.

Added Nuvoton | Ducky Support to QMK | ChibiOS
QMK is an embedded keyboard distribution that runs on ChibiOS—an RTOS. I added support for a keyboard I bought and used for a while.

The keyboard uses a Nuvoton NUC123 SoC. I first mainlined support for the Nuvoton platform to ChibiOS and then mainlined the keyboard support to QMK.

I am currently working on porting the platform to Zephyr.

WebSocket Draft 76 Implementation in Nginx
Developed the first-ever Nginx WebSocket patch based on draft 76, providing valuable insights into the limitations of the initial WebSocket specification drafts. Also, I utilized this patch to contribute to discussions aimed at improving the WebSocket specification.
