“You've got to start with the customer experience and work backwards to the technology. You can't start with the technology and try to figure out where can I sell it.”

Dennis Hernandez
Passionate Developer | Innovator | UI Problem Solver
Hi, I’m Dennis Hernandez, a self-driven software developer with a deep passion for creating intuitive and efficient applications. My journey into coding began in middle school when I discovered RealBasic on a MacAddict magazine demo CD. Since then, I’ve honed my skills in Swift, C++, Objective-C, and Arduino, developing projects that bridge software and hardware, from macOS and iOS applications to embedded systems using Raspberry Pi and Arduino.

Why I Code
I’m drawn to the challenge of building seamless, intuitive user interfaces—ones that don’t just look good but feel natural and responsive. My work blends low-level system programming with modern SwiftUI, allowing me to create high-performance applications that integrate C, C++, and embedded systems directly into the user experience.
Whether it’s optimizing an interface for smooth interactions, bridging Swift with low-level hardware control, or crafting tools that make complex workflows effortless, my goal is always the same: to create software that’s both powerful and elegant.
If you’re looking for a developer who can bring together interface design, hardware integration, and system-level performance, let’s connect!
