Kilo Code is an open-source AI coding agent (developer tooling built for the AI era) that meets developers everywhere they work: VS Code, JetBrains, the CLI, and the cloud.

• Helped design and build Kilo's Cloud/Teams/Enterprise offerings
• Shipped shared modes, letting organizations define and distribute custom agent modes across their teams

Senior Systems Engineer - Engineering Manager

Cloudflare (cloudflare.com) | July 2016 - September 2025

I've worn many hats while at Cloudflare. From building developer tooling for Cloudflare Workers (Cloudflare's serverless developer platform) to being an EM for Marketing Engineering to architecting and implementing Workers CI, a CI/CD pipeline built for developers shipping to the edge. I've learned a lot about how engineering organizations work at scale (culturally and technically).

CTO

Goodybag (goodybag.com) | December 2012 - July 2016

When I was approached to join a startup in Austin, TX, I jumped on the opportunity. I had heard that living and breathing the startup culture was a necessity in the software field, so I did it. The emotional and educational ride has been rewarding.

In 2014, I was unceremoniously named CTO.

Responsibilities

• Front-end development
• Back-end development
• Build and deployment strategies
• Manage developers
• Define product vision and development schedules

I learned a lot at Goodybag. Not just about software, but about culture. About the power of community and open source. About empowering employees to affect the companies they work for.

Technologies Utilized

• Node.js
• Nginx
• Heroku
• Postgres
• MongoDB
• Express.js

Systems Administrator

Health Management Associates (hma.com) | December 2011 - 2013

Going to a more corporate environment was a move I thought might make me more comfortable as compared to the chaos of school and contract work. The position asked for someone with Windows Sys Admin skills, web software development, and graphic design prowess. The band of job requirements was appealing.

Responsibilities

• Build and maintain company Intranet
• Produce various print media (company posters, table tents, handbooks, etc.)
• Weirdly, I ran the Photo Studio for doctor portraits
• Built custom Active Directory user search interfaces
• Built custom AS400 user search interfaces
• Standard Windows and AS400 system administration

Technologies Utilized

• PHP
• node.js
• C#
• Batch scripting

Software Developer

ENRG Consultants (enrgconsultants.com) | December 2008 - Present

Admittedly, this was originally a contract position that turned into full-time and is now back in contract mode, but I would rather have this position on its own. While I was in college, I was approached by Todd Boring, owner of ENRG. He asked me if it was possible to automate the work he was currently doing and to make his product real-time and on the web. Being an eager college student, I said, "of course."

Responsibilities

• Write software suite for managing monitoring jobs
• Provide general IT expertise for the entire company
• Maintain noise monitoring jobs

I developed and helped research the noise-monitoring solution ENRG provides for the oil, gas, and construction industries. Back in 2008, I was awful at design and their website and product reflects that. However, a new version is in the works. The point is, in 2008, I wrote a bunch of software that is still in use and supporting a company today.

Technologies Utilized (over the years)

• Apache
• PHP
• MySQL
• C# ASP.Net
• MsSQL
• Node.js
• Postgres

Multimedia Information Group Research Assistant

University of North Texas (unt.edu) | February 2008 - January 2009

After my 3rd semester in Computer Science at UNT, I was invited to help the Multimedia Information Group (MIG) with its research. At UNT, each research group is required to have two undergraduates. My CS3 professor recommended me to work with MIG because of my previous experience working with the web. My duties ranged from creating the group website, publishing results, running image processing benchmarks, and even writing a few lines of C++. Primarily, I was tasked with the public-facing website and publishing results.

Responsibilities

• Design, build, and maintain group website
• Build unit tests for the masters students
• Running benchmarks and curating results

Technologies Utilized

• PHP
• Wordpress
• HTML

Web Developer

Canonball Creative (canonball.com) | March 2008 - December 2009

Coming out of Royse City, I was a self-taught web developer and self-ascribed designer. When I started work for Canonball in 2008, I learned how to work with other people, and more importantly, I met real designers. I did a lot of client work and even some projects that are still live (see http://www.eisenberginc.com). I realized the vastness of the web community and with that realization came humbleness and humility.

Responsibilities

• Build standards compliant websites
• Support down to IE6
• Slice designs
• Brainstorm in product meetings

Technologies Utilized

• Apache
• PHP
• Wordpress
• ModX
• MooTools

Royse City ISD (rcisd.org) | June 2004 - December 2009

At the end of my sophomore year of high school, I was approached by the IT department to work as a technology intern. This was a lot more appealing than what my peers were doing for work. I ended up designing and developing the district website and managing all of the sub-campus web pages. I kept the job in college and worked remotely.

Responsibilities

• Design and build district website
• Design and build campus websites
• Implement Wordpress and train campus website managers
• General Windows/Novell systems administration
