After a 15-year career in music, Javier pivoted to data science during the pandemic, driven by an interest in AI and machine learning. The REACH apprenticeship provided a structured pathway, offering both skill development and project involvement.

## Refining the Member Experience

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

His initial project involved experimenting with sampling training data for algorithms, scaling from personal projects to datasets with 500 million rows. This work directly contributed to measurable business metric gains.

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.

## Cultivating a Collaborative Culture

LinkedIn fosters a collaborative environment, encouraging engineers to share data and technologies across teams. Javier actively engages with his REACH cohort and founded a data club for apprentices.

His advice for aspiring engineers, particularly those considering a [machine learning engineer career change](/ai-news/artificial-intelligence/2026/ai-job-boom-linkedin-data-reveals-doubled-hiring), is to identify and pursue passions, emphasizing the importance of understanding the business and social impact of technology.

This journey underscores the value of [transitioning to data science](/ai-news/artificial-intelligence/2026/matt-pocock-engineering-fundamentals-still-crucial-in-ai) and the opportunities available through programs like REACH for those with unconventional backgrounds.
