ABOUT

Who I am

ABOUT

I've been passionate about technology since childhood — I started exploring computers at a young age and have maintained a strong curiosity for understanding how systems and technologies work ever since.

I developed a self-taught profile, always seeking to learn by doing, test solutions, and deepen my knowledge. I enjoy solving complex problems, tackling technical challenges, and working in environments that encourage continuous learning and professional growth.

I have experience with high-volume data systems, microservices architectures, and integration with IoT devices using specialized protocols such as SNMP and LwM2M.
