Experience

I/O Throttling

I blocked cluster computations from crippling the NAS. Some operations are more taxing than others, so limiting bandwidth alone is insufficient. I wrote a file system to run on the compute nodes, which would adaptively rate-limit I/O operations based on their aggregate volume by type.

JavaScript Sandbox

I've embedded a JavaScript VM in an equity trading engine to provide a robust and safe live trading environment for the development of a rapid strategy and the refinement of an agile iterative process.

MySQL Timeseries Extension

I extended a MySQL engine to support time series as a fundamental data type. It was used by Lehman Brothers for equity trading research.
