About
Engineer, builder, and systems thinker.
I’m Jonathan Terrero, a Software Engineer I at OmniFlex Fitness and a biomedical engineering student at Florida Gulf Coast University. Terrero Labs is the umbrella for my work as an engineer: the projects, research, and skills behind them.
HeartWire is my health-tech startup, now being formally set up. It’s where the products live: MindMap, GastroGuard, SkinTrack+, HeartWire OS, and later GlucoLoop.
I treat the body and mind as systems: inputs, outputs, and patterns that can be measured, understood, and improved over time. Structured inputs and explicit hypotheses beat anecdotes when you’re trying to understand something that changes constantly — and the same rule applies to my own work, which is why every project here says what has and hasn’t been verified.
Outside engineering, I’m an Orthodox Christian, a powerlifter, and a Brazilian Jiu-Jitsu practitioner. Those shape how I approach problems: consistent, deliberate, and grounded in reality.
