Leonardo Barreiro - Engineer

Electromechanical engineer experienced on embedded systems and software. I bridge mechanics, hardware, and software to turn complex product execution into simple, clear, and reliable solutions.

Hardware to Software

From circuit design and PCB layout to firmware development and production C++ code.

Systems Thinking

Understanding of how mechanical, electrical, and software components interact in complex systems.

Practical Engineering

Real-world experience with industrial safety standards, AUTOSAR, MISRA, and mission-critical systems.

From Electromechanics to Embedded Systems

I started my engineering studies and, in parallel, took on freelance embedded projects. That pushed me to adopt solid software engineering practices to deliver reliable systems, and I ended up loving the fusion between electromechanics and software.

Before graduating I joined Globant as a backend developer for EA Madden and later led features as a Senior Developer while finishing my degree. I then moved to Spyrosoft to work on autonomous driving, building a small team focused on performance and safety for planning and control.

Now that I have my degree, I am returning closer to the physical world as an electromechanical engineer. The mix of cross-discipline and large-scale projects gives me a unique engineering perspective.

Autonomous driving optimization

C++ Software Engineer — Spyrosoft

Achieved ~15% reduction in on-route exception rate and unified two core environment modeling units without regressions, weeks before release. AUTOSAR & MISRA compliant.

Online gaming at scale

C++ Senior Developer — Globant / EA

Led client-server systems for Madden NFL 25, including a gRPC ranking pipeline stress-tested for thousands of concurrent users and headless scenario simulation.

Industrial safety systems

Electromechanical Engineer — Oil & Gas

Designed electromechanical safety and monitoring systems: H2S detection, vibration-based fault alerts with RF signaling, and diesel engine data logging.

Embedded & IoT projects

Freelance Engineer

Distributed RS-485/Modbus lighting control, IoT weather stations with wireless sensor networks, and high-power multiplexed lighting for commercial applications.

Work with me

I help teams design, review, and optimize electromechanical and embedded systems. If you have a challenging project, let's talk.
