Worked For
For me, programming is more than just a job; it's a process I'm genuinely passionate about. I enjoy challenges of building, designing, and iterating, which is not a straight line, it never is. But that's the beauty about being a developer I truly love.
I build websites and apps from the ground up. Whether it's the front-end design, the back-end logic, or the behind-the-scenes infrastructure that keeps everything running smoothly, I handle tiniest details so you don't have to. From minor tweaks and documentation to building a full-scale application from scratch. Take a look at my portfolio to see what I can do, and if you aren't exactly sure what you need yet, just reach out, I'd love to chat!

Lodestone - a C# WPF Minecraft Mod Manager
Most mod managers are a folder, a prayer, and a config file you're afraid to touch. Lodestone is drag-and-drop on the surface and an over-engineered, fully unit-tested layered architecture underneath. Here's the build, the bits that were actually hard, and the things I haven't finished yet.

The premise is simple and slightly paranoid: what if the server genuinely <em>couldn't</em> read your messages - not because of a privacy policy, but because of mathematics?

An ASP.NET Core MVC application with authentication, analytics, and a calendar - built for the one health metric nobody talks about, but everybody has.
View case study →My Experiences
Simple process.
In 3-steps.
Scoped proposal
A clear, fixed-scope proposal with timeline and cost. You see exactly what I'll build and what it'll cost, before any commitment.
02Build & launch
I build it, you review along the way, and we ship. Regular check-ins so nothing comes out of left field at the end.

Clean code.
Clean code.
Clear results.
I put my effort into development not because I need it to be 'done' - I do it because I love it. This is the most honest assurance I can give you. I put solid emphasis on how the systems are going to be used, adjusting myself to do my 110% each time.
I understand, I create, I test. Until you are happy.
Websites & brand presence
For businesses whose work is better than their website. A fast, precisely built site with the hierarchy and typography to be taken seriously, and a clear route from serious visitor to enquiry.
Lead & conversion systems
For firms with traction that leak enquiries. Intake forms, quoting flows, and follow-up workflows - the commercial machinery that turns visitors into qualified enquiries, and enquiries into clients.
Internal tools & applied AI
For teams losing hours to repetitive admin. Dashboards, admin panels, automations, and AI applied selectively - where it measurably cuts the load, not where it merely makes a demo.
