Who I am
A big-tech engineer who went independent to build with you.
Bernal CartinFounder & Lead Engineer, Garson Tech
I'm a software engineer with 20+ years of experience designing and shipping desktop, web and mobile applications.
I spent years inside large tech companies, then left the corporate world to do what I enjoy most: working directly with people to turn their ideas into real, polished products. No layers, no handoffs. You talk to the person actually building your app.
Whether you're a first-time founder with a sketch on a napkin or a business that needs a complex, production-grade app, I bring the same care: thoughtful architecture, honest advice, and software built to last.
Why Garson Tech
Everything you need in one developer.
Hiring me means working with someone who owns the whole journey: strategy, design sense, engineering and launch.

End-to-end ownership
