Hardware acceleration for deep learning frameworks.

* As the company's first employee, I single-handedly created RubySonar, an advanced type inferencer and indexer for the Ruby programming language. RubySonar includes a sophisticated inter-procedural flow analysis, similar to its cousin PySonar. Until today RubySonar is still the most powerful type inference and indexing tool you can find for the Ruby programming language. The code is open sourced and can be found at https://github.com/yinwang0/rubysonar.

I worked on the company's new product, Java Webapp Security. I tracked down and fixed some ultra difficult bugs and improved the overall code quality and performance.

Code obfuscation technology for JavaScript. High availability cluster management.

I single-handedly created PySonar, an advanced type inferencer and indexer for Python. It is in daily use processing all of Google's Python code, producing high-quality semantic index for internal developer services such as Grok and Code Search. A completely rewritten and improved version of PySonar (named PySonar2) can be found at my GitHub repo: https://github.com/yinwang0/pysonar2. Until today PySonar2 is still the most powerful type inference and indexing tool you can find for the Python language.
