Maciej Fijałkowski

I am a core developer of the PyPy project and a software freelancer. I was involved in PyPy activities since Google Summer of Code 2005, since then working on pieces like Just in Time compiler, Garbage Collection, the Python interpreter, NumPy support and pretty much almost every other piece that constitutes PyPy codebase. I am also an occasional contributor and commiter to the Twisted project as well as CPython, the main python interpreter.

Projects

By far my main interest is working on PyPy. I'm also interested in data analysis and visualization, especially those related to coding and coding related activities. One example of a very simple data-visualizer is jitviewer, a flask-based webapp I wrote for visualizing JIT-compiled code.

PyPy is also very agile - we have tons of automated tests and a continuous integration setup as well as continuous deployment. I'm also interested in test and deployment automation.

Consulting

I offer PyPy and python related consulting. Non-exhaustive examples of what I can do for you:

• Make your codebase run on PyPy. This usually requires assesing the set of C dependencies, looking for replacements and/or adjusting the current ones.
• Assess the performance of your project, write benchmarks, evaluate them both on PyPy or CPython, provide guidelines and/or optimize the codebase.
• General performance or quality related work. Custom test runners, performance analysis tools etc.
• PyPy trainings, Python performance trainings
