Profile bio

About David Zalewski

I have spent years working on financial analysis and accounting for companies with global reach in order to better understand the movements of markets and help the people I am working for adjust their strategy to match real business trends as they are happening. This is really a combination of a number of different skills that I have cultivated over the years.Perhaps what has served me best has been my ability to take data and use it to build effective models that give an accurate idea of where markets will go. I do this by employing a number of techniques and developing innovative approaches to understanding the information I have available so that I can better predict what it will do next.I also excel at complex budget creation and management. In previous jobs I have developed the operating budgets for companies extending out a decade from their initial implementation, setting goals and expectations based on a keen understanding of the business and how to stay ahead of major trends while taking advantage of opportunities as they present themselves.These are just some of the skills I bring to any job I am a part of. Companies that I work for get a talented, innovative thinker who is capable of taking raw data and translating its message into a guide for the future.

Listed skills include Organizational Development, Internal Controls, Investments, Financial Modeling, and 8 others.
