Jeffrey D.

Senior Software Developer. Web, Desktop and Database

I am a full-stack developer, with over 26 years of experience in enterprise-level development. I can quickly create a new system custom-tailored to your needs or fix any existing system. I am passionate about delivering best-fit solutions for your business. In the past, I have created enterprise-wide incoming request management systems that can handle several 10s of thousands of requests/per day. I have developed dozens of custom websites. I maintain existing websites and systems. I also optimize critical data flow throughout the enterprise and individual database queries. Recently, my projects have branched out into machine learning and A.I. This additional resource can move almost any project forward more quickly. Much of my work in automation eliminates redundant, tedious work and allows employees to focus on more meaningful and productive endeavors.
