OBJECTIVE
I am a lead machine learning engineer with a focus in time series modeling.
I place a heavy emphasis on building models and software in a reusable and modular way so that the work can be built upon and leveraged by multiple use cases. Therefore, I aim to build up a suite of sustainable tools for time series modeling that can be easily leveraged and expanded.
People have described me as an effective communicator with the ability to lead and influence people towards a shared goal. I have frequently driven collaborations between different teams so that we can work together on a shared solution saving us both time and resources. Additionally I am consistently tapped as a mentor to younger developers to help them grow their modeling and software engineering skills.
I am looking for opportunities to remain in a technical role while also driving use-cases in a tech-lead capacity in the space of machine learning engineering.
