Summary

I am a highly analytical and progress-driven individual who enjoys locating and employing ways to improve how I manage the tasks and challenges of my professional life. This includes both the smaller details, which I find especially interesting to focus on, as well as the larger picture, where a positive change can result in significant benefits in the long term.
Living in a foreign country has invigorated and deepened my appreciation for languages, and communication in general. I find it very satisfying to compare and understand how ideas are expressed differently, depending on the context and culture.
