01 / About

Engineer. Designer. IT pro.

I'm a software engineer and designer based in Crestview, Florida, with more than 17 years in IT.

I hold a bachelor's degree in computer science and an advanced degree in software engineering, on top of hands-on vocational training that started when I was young.

My background is computer repair and IT support. That work taught me how technology fails in the real world, and it still shapes how I build: simple to use, hard to break, and easy to support.

Today I write full-stack software in VB.NET, C#, TypeScript and SQL. I build cloud APIs, web portals, desktop apps and code that talks directly to hardware. I also design what people see: graphics, interfaces and on-screen content.

Engineering and design rarely come from the same person. With me, they do. I run YUR IT PRO LLC, where I build, host and support software for businesses on servers I manage myself.

  1. I engineer

    Cloud APIs, web portals, desktop apps and the code that talks to hardware.

  2. I design

    Graphics, branding, interfaces and on-screen content people actually enjoy using.

  3. I support

    Computers, networks and servers, built, repaired and kept running.

One person, no handoffs. What you picture is what ships.

The standard I work by

And whatever you do, do it heartily, as to the Lord and not to men.

Colossians 3:23 NKJV

07 / Questions

FAQ

What makes you different from other IT professionals?

Most projects pass between a developer, a designer and an IT tech, and every handoff loses time and detail. I do all three. I write the code, design what people see, and set up and support the hardware and servers it runs on.

What languages and platforms do you work in?

I'm fluent in VB.NET, C#, TypeScript, JavaScript, SQL, HTML and CSS, and proficient in Python, PowerShell and XAML. I build on ASP.NET and ASP.NET Core, SQL Server, WinForms and WPF, on Windows and Linux.

Can you take over software someone else wrote?

Usually, yes. A lot of my work is fixing, modernizing and extending existing ASP.NET, VB.NET and C# systems. I'll look at what you have and tell you honestly whether to fix it or replace it.

Do you still do computer repair and IT support?

Yes. Repair, upgrades, networking and server work are where I started, and they're still part of what I do for clients.

Where will my application be hosted?

On dedicated servers I manage, connected by fiber internet and built on enterprise-grade hardware with battery backup to stay online through outages.

Do you work with clients outside Florida?

Yes. I'm based in Crestview and serve Okaloosa County and Northwest Florida in person, and I work remotely with clients anywhere in the United States.

Tell me what you need and I'll tell you honestly how I can help. No commitment, no pressure.
