I first discovered my passion for programming when I was 12yrs old after getting a book to learn C++ in 21 days. I'm grateful to have gotten such a start as the lessons I learned then both in programming and object oriented design have stayed with me through my entire journey. Eventually I moved on to learn other languages like Visual Basic, Liberty Basic, Python, PHP, JavaScript, Lua, Java, etc., etc. I programmed primarily as a hobbyist for about 16 years working on projects that interested me that I could learn from until I finally broke into the industry professionally in 2016. I started as a web developer and was quickly moved up to a SR Engineer as my experience clearly shined through. I had the privilege of getting to learn and work on a large team of developers that followed a strict dev ops process to ensure that we worked together to deliver on excellence. Since 2016 I have specialized in NodeJS applications. Mostly on a MEVN stack (Mongo, Express, VueJS, Node) using NuxtJS for the front-end and MoleculerJS Microservices for the backend. I am well versed with this stack and every part of the development process that it entails. I can help you plan, build and deliver your next business application or project all the way from gathering requirements to actually implementing the solution. I work quickly and efficiently and deliver quality solutions that stand the test of time. My longest running software in production so far actually had an 8 year run (it was a simple JavaScript UI for expediting note taking and troubleshooting for Medtronic Diabetes pump support specialists, they just retired it last year for something that fully integrates with SAP). I consider myself an especially great asset to startups and small-medium sized organizations due to my wide range of experience and my ability to perform in various roles surrounding software engineering. Not only can I help you develop an amazing business solution, but I can help your team implement and follow a proper dev ops process and teach them to achieve success.
