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.

-Tools/Platforms/Software- -Standard Google Workspace Apps: Sheets, Forms, Docs, Gmail, etc. -Automation: Google Apps Script, Zapier -Form Builders: Cognito, Google Forms, Jotform, Typeform, Gravity Forms -Diagram and Visualization: Miro, Zoom Whiteboards, Sheets, Looker -Project Management: Trello, Google Sheets/Calendar, Monday.com -Communication: Gmail -How The Tools I Build With Can Be Applied- -Business Process Automation (e.g. automate your recurring processes) -Alerts and Reports (Generate and send reports to customers, stakeholders, etc.) -Data Visualization and Analysis -Integration with Your Platforms(Do all of the above by connecting the apps you use to your Google environment) -What I Can Do For You- I design process automation systems, integrations, and BI dashboards centered around Google’s environment. Google makes it easy to share/set permissions for every person that needs access to your systems and has a thriving ecosystem of freemium plugins that facilitate integrations with other services like Trello, Quickbooks Online, Salesforce, Shopify, etc. If free-tier plugins are insufficient or missing desired features, the Apps Script environment makes the development of custom functionality seamless. If you would like to discuss what more can be done to make your life easier with the platforms you are already paying for, just shoot me a message so we can set up a call. -About Me- I started designing BI Dashboards back in 2016 at BellTower Technologies LLC. During my time at BellTower Technologies, I created many BI dashboards in Google Sheets used by nearly every employee. The projects I worked on ranged from dashboards for tracking workflows to KPI visualizations used daily by the CEO, several of which are still used today. I also attended Texas A&M to study computer science on an engineering scholarship starting in 2019 but left during the pandemic to work. A couple of systems I have designed and implemented recently are: -Automated document generation using Google Doc templates and data in Sheets(Either manually input or automatically collected) -A small Trello/Google Forms integration -An integration between Enlighten, a well known solar system management platform, and Google Sheets -Mail-merge configured through an interface in Google Sheets
