What I do
What I can help with.
I design and build full-stack apps, mostly on Base44. These are the six things people ask me for most. No packages and no public rates: tell me the problem and we'll work out the rest.
I'm also looking for a remote internship. If you're hiring, that's the thing I want most right now. About internships

Fit check
Are we a good fit?
Honest answer first, so nobody wastes a week. Tap the ones that sound like you.
Who I work best with
People who know good work can't be rushed.
Fit-o-meter0/4
Tap the ones that sound like you.
Probably not a fit if...
No hard feelings. Better to say it now than halfway through.
- You need it live tomorrow and don't mind how it gets there.
- You want a quick patch over something that needs fixing properly.
- You want someone to agree with everything rather than ask questions.
- You mostly want the cheapest option going.
If that's you, that's completely fine. I'll point you somewhere better if I can.
How I work
Questions first. Code second.

FAQ
Questions people ask first.
The straight answers. There are more on the FAQ page.
I design and build full-stack apps, mostly on Base44. That covers UI/UX design, full app builds, backends and integrations like Stripe and Resend, security reviews, SEO and performance, and AI agents and automation.
I don't publish rates. Every project is different, and a number on a web page can't know what yours needs. Get in touch and I'll tell you honestly if I'm the right fit.
It depends on the project, and I'd rather give you an honest estimate than a nice-sounding one. Once I understand the problem I'll tell you roughly how long it'll take and what could make it longer. I can move fast (Hattle went from a paper sketch to shipped in 8 hours), but good work can't be rushed.
Mostly email, with regular updates and links you can click through. I explain things in plain English and flag problems as soon as I find them. Good communication comes up in my reviews a lot, and I'd like to keep it that way.
Yes. A lot of my work starts that way. I go through what's there, tell you what's solid and what isn't, and then we decide whether to fix it or rebuild parts of it.
Mostly, yes. I'm a Base44 Partner and it's the platform I know deepest. I'm also learning Rust and desktop apps with Tauri. If your project genuinely needs a different stack, I'll say so up front rather than take the work and figure it out later.
We agree who owns what in writing before anything starts, so there are no surprises at the end. Either way, I walk you through how it all fits together so you're not dependent on me.
