About Me

I'm a Tech Lead and Senior Data Engineer at Telefónica's Chief Data Officer (CDO) unit in Madrid, Spain. With deep expertise in Google Cloud Platform and a passion for building data platforms at scale, I architect systems that process billions of events daily and enable data-driven decision making across organizations.

I hold Google Professional certifications in both Data Engineering and Machine Learning Engineering, and I believe that programming is not an art — it's an engineering discipline that can be taught, learned, and continuously improved.

When I'm not building data platforms or mentoring teams, I create educational content to help others break into tech with an engineering mindset.
