I am a Mechanical Engineer who transitioned into Software Engineering, bringing a systemic and hardware-aware perspective to the digital world. With 3+ years of experience as a Technical Lead in a startup environment, I've architected and deployed 8+ health systems.

Currently, I am deep-diving into Java Backend Engineering and High-Performance Systems.

• 🛠️ Current Focus: Java 21, Spring Boot, and Concurrency.
• 🎹 Maker Side: Building custom MIDI controllers and exploring Audio Processing.
• 📡 Authority: I share my building process and home-lab setups on my YouTube channel (2k+ subscribers).

A SaaS focused on flood registration and real-time mapping. Built to help communities during severe weather incidents. Tech: Next.js, PostgreSQL, Docker.

Convert serial to MIDI, for MIDI controller prototypes with Arduino. Technology: Java 17, Serial Communication, MIDI Protocol.

I contributed to the KeyboardScanner project, an open source Arduino-based MIDI controller firmware, for to reuse keyboard keys, alongside Daniel Moura, the original author of the repository.

My contributions included:

• ✅ Added support for FATAR TP40, Kurzweil SP76II, MAudio Axiom Pro configuration and schematics
• 🔧 Implemented velocity sensitivity curves for more expressive key response
• 🎛 Start of added support for potentiometers to extend control capabilities
• 🧩 Suggested restructuring the codebase into reusable modules

This collaboration improved support for additional hardware and enhanced the usability of the project for diverse keyboard matrix configurations, helping to make it more modular and easier to maintain.
