A dedicated and light-hearted software developer who loves to get things done and make teams thrive.

I love taking on big problems head on – nothing is too big to be broken into manageable parts. The less I know about the problem, the more for me to learn. Recently I have enjoyed being an operational lead at Backlight, a global media technology company. With me on your team you can expect an optimistic and fun atmosphere along with good forward momentum.

Part-of-Speech Driven Cross-Lingual Pronoun Prediction with Feed-Forward Neural Networks.

Association for Computational Linguistics · Sept 2015

For some language pairs, pronoun translation is a discourse-driven task which requires information that lies beyond its local context. For cross-lingual pronoun prediction, we suggest a neural network-based model using preceding nouns and determiners as features for suggesting antecedent candidates. Our model scores on par with similar models while having a simpler architecture.
