Kimberly J. E. Williamson is a home-grown data analyst with experience in financial and budget analysis, business tax management, commercial lease analysis, and administration, among other areas. Having built a reputation for proactively learning whatever is needed to excel in her business or personal projects, she loves diving into data and wrangling it into an intelligent form as well as creating best practice processes for the creation, management, and usability of data.

Kimberly often self-contracts financial or data analysis work through her own company, Strategic Resource Development, LLC, and financially manages this company as well as her husband's company, Sophos, LLC, which owns rental properties. She has worked in a diverse array of environments, such as nonprofit, medical property management, the private loan market, banking, engineering, project management, and so on.

Although this is the first time she has been formally asked to provide a technical review, in the past she has contributed heavily to the creation and editing of complex in-house accounting and data management procedural guides for commercial lease management.

I'd like to thank both Jesus Christ and Packt Publishing for giving me the opportunity to explore this new avenue to use my skills (and learn some new ones) as a technical reviewer of this book.
