Full Stack Dev | SaaS MVPs, React, Node.js, Bubble, AI + Automation
You're not hiring just a developer —
You're partnering with a problem-solver, a builder, and a systems thinker who gets things DONE.
Maybe you need to launch a SaaS MVP fast.
Or automate your business using AI + No-Code tools.
Or you’ve worked with devs who ghost, overpromise, and ship spaghetti.
I get it.
That’s why I don’t just write code — I build with you, like it's my own startup.
