Founder & CEO

Sergio Reyes

I started programming in high school—building websites, small games, and tools just to learn. Over time that turned into a focus on software engineering, iOS development, and building systems that make work simpler. I care about practical products: fast UX, clear code, and fewer moving parts.

I launched Resync Technology to help NYC small businesses, contractors, and growing teams upgrade their software without hiring a full engineering department. If you need an app, a dashboard, an automation pipeline, or a clean rebuild of something that’s slow or messy, I can help you scope it and ship it.

Whether it’s an iOS app, modern website, internal tool, or payment + invoicing workflow—I believe great software should feel simple, dependable, and designed around real people.
