About
I'm Josh. I build things that work.
I'm a full-stack developer who specializes in turning business problems into working software — quickly and with minimal hand-holding. If you have a vague idea, a spreadsheet you hate, or a process you want automated, I'm the person who can take that and make it real.
I've built a full insurance renewal management system that a client actively pays a monthly retainer for. I've built a contracting company's entire web presence from scratch with near-zero direction. I've built a cross-platform mobile app with AI recipe generation and Firebase integration.
What I do differently: I use AI tools throughout my development process, which means I build faster, catch bugs earlier, and deliver more for the same cost. And when I ship something, I don't disappear — I maintain it, improve it, and grow it with you.

How I work
What makes me different
I own the entire build
No handoffs between design, dev, and QA. I take it from concept to deployed — faster and with fewer broken phones.
I need minimal briefing
You share your vision. I ask the right questions. Most of my clients never write a spec document.
I build relationships
I'm not a gig worker. I maintain what I build. Most clients are still working with me months or years later.
