About Me

Correlation between personal interests and engineering approach.

🏔️

Mountaineering

UDP Mountain Group

My connection with nature and the extreme environments of the Andes was the direct inspiration for focusing on telecommunications.

Experiencing total disconnection in the field led me to co-design back2home, solving real connectivity problems where commercial networks do not exist.

Music

Lead Guitarist (UDP CMP)

As the lead guitarist in the UDP Popular Music Company, I find the perfect balance between creativity and structure.

Music has forged in me a strong discipline and the ability to solve complex problems by breaking them down into structured patterns, skills I apply daily in software development and network design.

Experience

Professional Internship I · Jan - Mar 2026

📺
Sercom
Digital Broadcasting · ISDB-Tb
During my internship at Sercom S.A. I acquired fundamental practical knowledge on digital broadcasting systems in the ISDB-Tb standard. This field experience allowed me to develop skills in equipment configuration and support, network infrastructure design for remote access, and advanced diagnostics of high-power transmission systems.

Configuration and support of digital broadcasting equipment under the ISDB-Tb standard, including signal quality analysis via SNR, MER, and BER parameters.
