After a 15-year career in the music industry, Javier pivoted to data science during the pandemic due to his interest in AI and machine learning. The REACH apprenticeship provided a structured pathway that provided both skills development and project participation.

Improving member experience

Currently a machine learning engineer on LinkedIn’s Feed AI team, Javier works with large datasets, processing billions of rows to refine recommendation algorithms. He utilizes Python, Scala, and Java for data analysis and machine learning experiments.

His first projects involved sampling training data for algorithms that scaled from personal projects to datasets of 500 million rows. This initiative directly contributed to improving tangible business metrics.

Javier also participates in on-call shifts, managing the global LinkedIn feed and making critical, split-second decisions to ensure a seamless member experience for millions of people.

foster a collaborative culture

LinkedIn fosters a collaborative environment and encourages engineers to share data and technology across teams. Javier is actively involved with REACH colleagues and established a data club for trainees.

His advice for aspiring engineers, especially those considering a career change to become a machine learning engineer, is to identify and pursue your passion, and emphasizes the importance of understanding the business and social impact of technology.

This initiative highlights the value of transitioning into data science and the opportunities available through programs like REACH for those from unconventional backgrounds.
