I’m a C++ and Python coder, and I’ve recently started SpreadServe to address the issues around spreadsheet use on the trading floor. You can see some of my code here on github. You can also find me on Stack Overflow and Hacker News. I’m available for interesting projects on a day rate. Leave a comment with your email address here if you want to discuss opportunities, or email me at john.osullivan@spreadserve.com

    Came across your blog today and thought you might be interested in this free podcast series interviewing people from the Algo Trading community.

    Let me know if you find it interesting.

    Hi, I’m working on a new book would be interested in a fixed income perspective – mail me if interested, cheers!

    Hi, in case you’re interested I finished the book on ‘Algorithmic Trading and DMA’. Essentially it tries to merge the microstructure approach of Trading and Exchanges with actual execution, hence I thought it might interest you.
    Admittedly the coverage is mainly focused on equities, etc but there is some coverage of fixed income.
