About Andrew Janke


I'm a professional software developer with more than fifteen years of experience, specializing in data and analytics platforms for the energy trading industry.

I have extensive experience with Java, Matlab, and SQL, and in particular the integration of them with each other. You could say I'm a full-stack analysis platform developer: I've done everything from hardware selection and infrastructure design to user-facing GUIs and acceptance testing.

After graduating from the University of Oklahoma with a degree in Computer Science, I spent several years building GUI programs and databases for weather study systems. I discovered the finance industry when I was recruited to join Citadel Investments in 2003 and build systems for their Energy desk's Meteorology team.

That led to five-year stints at Citadel and Louis Dreyfus Highbridge Energy (now Castleton Commodities), building research and trading systems and learning the energy trading business. I specialized in working closely with researchers and traders to create analytics and risk management platforms that were in daily commercial use and which evolved quickly in response to market events or new trade ideas.

Now I'm an independent software-development consultant, serving firms that need nimble analytics and data systems or business knowledge of energy trading. I'm available for engagements of any size, from one-hour tech strategy consultations to year-long implementation projects.

My distinctive specialty is taking Matlab beyond its typical uses: applying software engineering best practices, external systems integration, and advanced programming skills to produce large, robust, production-quality systems and unusual applications features. If you need to do something ridiculous or heavy-duty with Matlab, I can help you. I can also help your research team apply industry-standard best practices for software development like source control, bug tracking, and release management to your process, increasing project velocity and reducing risk without getting your researchers bogged down in bureaucracy.

I also contribute to Open Source projects. My main focus there is Mac Homebrew, where I've been a core maintainer since October 2015. You can find me on GitHub and Stack Overflow (where I'm a Top 2% contributor, and in the Top 20 for the Matlab tag).

I'm based in Brooklyn, NY, where I've lived since 2012.
