ABOUT

Data Derivation is a dedicated technology resource for small businesses. While many companies offer software solutions, few provide the ongoing support needed after the sale. Often, small businesses are run by a single owner or a small team, making them less attractive to larger technology providers. This can lead to small businesses missing out on essential technologies due to the steep learning curve and time required for implementation.
At Data Derivation, we bridge this gap by offering personalized support and training. We help you set up only the services you need, establish your online presence, and implement these solutions across your desktop, tablet, and mobile devices. Our goal is to make technology accessible and manageable, so you can focus on what you do best while we handle the tech.

OUR TEAM

Founder
After being honorably discharged from the United States Air Force in the fall of 1982, I joined my dad's real estate business in the Castle Hill area of the Bronx. At that time, his office had about four agents, and I quickly learned the trade, becoming successful over the years.
In 1984, we purchased a few fax machines for the company, which was considered cutting-edge technology for small businesses. This sparked my interest in computers, and I asked the same salesman about them. He was happy to sell me all the computers I wanted, even though I had no idea how to use them. Fortunately, I had a burning desire to learn programming and apply this fantastic technology. Developing applications for our business back then gave us a significant advantage over our competitors, and we fully utilized this edge. However, being self-taught in this field has its pros and cons. Learning, developing, maintaining, supporting, and keeping up with technological advancements is challenging, even for an expert. This was the dilemma I consistently faced while also financing my own sanity. Eventually, I was able to hire some help and get more work done.
Over the past year, we have designed software solutions that utilize current technologies and are adaptable to future changes. With the knowledge I have acquired over the past 30 years, I can help you find the right solution for your business and provide the ability to scale as you grow.

Support
I began my career in the real estate industry as a data entry clerk for a broker in New York who specialized in REOs. For five years, I entered data and learned about the valuation process for residential properties. However, I eventually decided to pursue a different path and enrolled in school for medical billing and coding. After 15 months, I realized that this field was not my passion.
I did some work with my father-in-law, Patrick Naraine, who was developing a real estate application. After a few months, he asked me to become more involved, and I made it my primary focus for the next three years. During the development process, I obtained my real estate licenses to gain better insight into the practical side of the real estate business.
Over the same period, I actively sold and rented properties, which helped me identify the tasks that technology could address in the industry. Although I have no formal training in software development, I am a quick learner and can offer sound suggestions to developers for the Tennessee market.
Since I have worked on this application from its beginning, I am uniquely qualified to assist you with any support questions you may have.

Finance
In 1997 I started work as a secretary in a real estate office in Bronx, NY. About a year later I was hired by Patrick, who in 1999 became my husband. For the year before being married to Patrick, I worked as his assistant in buying, selling, and processing residential mortgages. As an assistant and then wife, I learned the financial aspect of running a multi-facets business, which changed as the technology advanced. We worked for years on his dream of completing the Real Estate application he started in the mid-eighties. Today, twenty years later and many years of experience, we are offering our services to small business owners just like us.
