Background

About Mario Souza

I build data infrastructure that powers next-generation hardware operations. With a background in photonics and semiconductor test engineering, I specialize in designing scalable, cloud-native data systems that bridge manufacturing, product engineering, and operations. At Lightmatter, I architected and now lead the development of our Hardware Data Platform—a modern stack combining AWS, Snowflake, Dagster, dbt, and Sigma Computing—while mentoring a small team of engineers to deliver data products for yield analysis, SPC, and test-to-design feedback loops. Before that, I led Aeva’s migration to a full cloud data platform, unifying 40+ manufacturing steps into an integrated analytics pipeline. I thrive in fast-paced, cross-functional environments where system design, scalability, and real-world impact intersect. My approach is deeply hands-on: I code, I design, and I think in abstractions—always aiming to build systems that outlive specific tools. and myself -)
