# Marina Rosa

> Marina Rosa (amphetamarina) is an AI engineer from Rio de Janeiro. This site uses plain, gentle language and highlights four open source projects she is building now.

## Bio

Marina works with AI in cybersecurity. She learned by making small worlds first: games, scripts, Linux servers for friends. That grew into production software, including Bitcoin.com and eCash wallet work, plus SRE, APIs, interfaces, and teaching.

In 2022 she explored early generative image models, including a public tattoo collaboration with a startup. She still asks the same question: how do we keep AI tools legible and humane?
