Fort Myers, FL · Software Engineer + Biomedical Engineering
I'm Jonathan Terrero. I build health-tech systems where physiology meets software engineering.
I'm a Software Engineer I at OmniFlex Fitness and a Biomedical Engineering student at Florida Gulf Coast University (minors in Physics and Computer Science). Outside of that day-to-day work, I run HeartWire, my own health-tech studio, where I design and ship clinical and consumer tools end to end.
This site is part portfolio, part system map. When a project is live, it is linked here, not just described.

SkinTrack+
Active DevelopmentLesion and skin condition tracking with environmental correlation
Tracks skin conditions over time and ties them to environmental and behavioral inputs. Built to identify patterns, not just log events.
PythonComputer VisionSupabase Modular Knee Brace
PrototypeAdaptive biomechanical support system for knee stability and recovery
A modular knee brace focused on stability, load distribution, and real-world use. Designed to adapt to different recovery needs.
3D PrintingCADBiomechanicsHeartWire Agent Suite
Active18 domain-specialized Claude agents for engineering, finance, trading, and content ops
A personal bench of 18 specialist AI agents — each a Claude Code skill with an explicit role, activation trigger, persona, and capability list — spanning software engineering, hardware, finance, trading, legal, tutoring, and content.

System philosophy
Human health is a system, just like engineering. Engineering is an applied discipline, and nothing is truly disconnected, especially when it comes to the body.
Observable inputs include behavior, mental and emotional state, physiology, and environment. Every input and output forms measurable patterns, constraints, and potential interventions.
Learning about yourself means learning your own health. The solutions are often simpler than expected. Reduce noise and confusion. Increase and consolidate the signal.
Structured inputs, alignment, and explicit hypotheses outperform anecdotes when you are trying to understand a system that changes constantly.
