Senior🎓
Top SchoolRafa Couto is a Senior Consultant and seasoned application developer with 11+ years crafting embedded firmware, cloud-native DevOps, and GNU/Linux systems from Pontevedra, Spain. He blends low-level microcontroller work (AVR, STM32, nRF5, ESP) with modern infrastructure skills—Docker, Kubernetes, Proxmox, pfSense—delivering R&D, IoT and automation solutions for both startups and industrial projects. As lead of his Redefol consultancy he routinely modernizes legacy stacks into containerized, scalable services and contributes to FLOSS and community hardware efforts. His open-source contributions include Galician localization for the widely used Marlin 3D printer firmware and practical tooling enhancements for Apache Mynewt’s embedded debugging flow. Comfortable switching between C/C++, Rust, Go and PHP, he pairs electronics design and 3D-printing tinkering with production-grade software practices. Always learning, he brings a maker’s curiosity to institutional engineering problems, favoring reproducible, community-first solutions.

Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:1 review, 8 commits, 5 PRs in 5 months
Contributions summary:Rafa primarily contributed to the detection and configuration of various programmers for debugging and flashing embedded systems. They modified scripts to identify connected programmers like ST-Link and J-Link using USB device ID checks, and integrated these detections with OpenOCD. Additionally, the user implemented a tone generator using the PWM peripheral for the buzzer, including associated driver and application code. This work suggests a focus on hardware interaction and debugging tools.

MarlinFirmware/Marlin
Sep 2015 - Dec 2016
Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
Role in this project:Localization / Internationalization Specialist
Localization / Internationalization SpecialistContributions:7 commits, 8 PRs, 9 comments in 1 year 2 months
Contributions summary:Rafa primarily contributed to the localization of the Marlin firmware, specifically focusing on the Galician (gl) language. Their work involved creating and updating language files (language\_gl.h) by translating LCD menu messages and other user interface elements. The commits demonstrate a deep understanding of the firmware's text strings and the process of adapting them for different languages, and includes updates to align with newer firmware versions.
