I use AI tools to build faster and at a fraction of what agencies charge. You get a custom-built product, not a Squarespace template.

A clean, fast, mobile-ready website for your business. Custom design, SEO basics, contact forms, and hosting setup included. No templates, no page builders.

From $750

Web Application

Interactive tools, dashboards, user accounts, database-driven features. For businesses that need more than a brochure site. Built with modern frameworks.

From $2,000

AI Integration

Add AI-powered features to your existing product or build something new. Chatbots, content generation, data analysis, workflow automation.

I'm Matt, the person behind ColdAngle. I build websites, web apps, and AI-powered tools for small businesses and independent creators.

I spent five years in hockey retail learning what real customers need and how products actually get used. Now I bring that same practical thinking to building digital products. I use AI tools daily to move fast and keep costs low for my clients.

I work best on small, focused projects where I can own the whole thing from design to deployment. If you need a Fortune 500 consulting firm, I'm not it. If you need something built well by someone who actually cares, let's talk.
