📈 Lambda School

Summary

I studied Data Science & Machine Learning at Lambda School and built several portfolio projects there that are still featured elsewhere on this site. The program emphasized applied machine learning, data engineering, backend development, data visualization, and shipping working products instead of staying purely academic.

Timeline

Contributions

Student Experience

This was the period where I was deep in applied machine learning work every day. The focus was not just learning concepts, but turning those concepts into working software, data products, and portfolio-ready projects that could actually demonstrate technical ability.

Machine Learning Topics

Core subjects covered during the program

Engineering Stack

Tools used to turn coursework into real implementations

Shipped Project Work

The program emphasized making things that worked end to end

Projects From This Period

Several projects I built during Lambda School already have their own detailed write-ups in this portfolio. This page is the program-level overview that ties them together as part of the same learning and shipping period.
