I'm 21. Coding has been my hobby since age 8. I get to work in heaven. I am the luckiest man alive (or, will be, once I get married). I've been using AI intensively to supercharge my productivity for 2 years now. Sorry to my coworkers who got fired as a result, but when technology changes, we ALL have to adapt. Some web developers I know are very specific in what they do. They're excellent at JavaScript, for example, but they can't code CSS or PHP at all. I'm not like them. I have broad experience from Composer to Web Host management to Calculus to Server configuration -- things that often go overlooked. Before working with me: - Let me know your availability windows and I will conform to your schedule. I work odd hours and often sleep polyphasically. - Consult me if you're undecided about anything. We can call if you want. I've been in the coding space for so freaking long at this point, and it's sad for me to get paid to work on - I like to be told the full scope (i.e. I'm working on a small part of a larger project). There are often small decisions that are impacted by the larger whole.

I am a backend engineer from Helena, Montana with 12 years of experience and a BS in Computer Science from Purdue University. If I'm not writing code I'm either mountain biking or skiing. I am an expert in task automation, finite state systems, data processing, data modeling, migrations, and API integrations. I have worked on dozens of projects aimed at streamlining business processes, with a focus on integrating products and services both internal and external. Other than APIs and automation, I specialize in Asp.Net and back-end architectural design/programming, but I can take on a wide variety of projects, small start-up MVPs, micro-services, API integrations, complex data migrations, as well as larger projects that involve heavy architectural work. My skills include: • ASP.NET Core MVC/RazorPages/C# • Entity Framework + Core • MS SQL/Oracle/MySQL • API Integrations (REST APIs, SOAP, WCF, GraphQL, plus others.) • Automation • ETL and Data Integrations • Business Analysis/Project Management/Lead Development • Expert in CRMs Thanks for reading!
