    I love technology and learning new languages, frameworks and platforms. I've been an I.T. professional for 25 years and was a computer enthusiast/programmer before I made it a career. I have worked as a consultant on many large & complex projects at Fortune 500 companies. Although my experience has been large corporate systems (ERP, e.g. Oracle PeopleSoft), I have found that I want to be more involved in startup projects using modern tools and techniques. To keep current with technology trends, I often work on side projects, some of which never see the light of day and others that have a significant user base on the public web.

    Greetings - I'm a legendary medium-enterprise tech-stack architect with experience from top-level down to granular implementation. Need to connect branch offices to a centralized system without fear of downtime or compromise? I'm your dude. Can't figure out why your web applications are running slowly? I'll evaluate your code. Looking to maintain data sovereignty? Let's sit down and talk about "private cloud" infrastructure and how it can save your business thousands in monthly charges while keeping all your data on hardware YOU own. I've been in the tech sector since I was in high school, and maintain triple competencies in network engineering, systems engineering, and web application/full-stack development. I have a reputation in maintaining and building global infrastructure for small enterprises, helping them make that transition from six figures to eight figures in global revenue, based on incomparable tech stack builds. BUT -- where I have the edge over other candidates -- is in my knowledge and instincts at a granular level. Which particular service is causing headaches across the entire tech stack? I can find it and offer alternatives. No task is too big to architect, but no task is also too granular to escape a deep-dive.
