Our story

A place to learn, build, and belong.

Code School of Guam began with a simple gap: people here should be able to learn software development with real instruction and local context.

Why we exist

Bringing opportunity home.

Growing up in Guam, I did not know software engineering was something I could do. I discovered coding bootcamps after moving to the states, completed Actualize, and found my first engineering job.

When I looked back home, I could not find a comparable path. I founded Code School of Guam in 2024 so people on our island could learn with an instructor, practice consistently, and build applications they could explain.

Our first class graduated in June 2025. Graduates have taken different paths, including software work and teaching. Their progress comes from their own effort, supported by a program grounded in real projects.

“I want everyone to feel what I feel — that if there's something I want to build, I can just build it.”
Leon Shimizu, founder

Graduate paths

What learning can lead to.

Every student brings a different goal. These are two paths graduates have taken after CSG.

Software work

Alanna Cruz

Alanna signed up the day before class began, unsure whether she could do it. After CSG, she continued building her software career and now works at DMR.

Teaching the next generation

Audreana Crane

A graduate of CSG's first cohort, Audreana now introduces students at Father Dueñas Memorial School to coding.

The founder

Meet Leon.

Leon Shimizu

Leon Shimizu was born and raised in Guam. He studied at Actualize Coding Bootcamp in 2021 and became a software engineer before graduating.

He founded Code School of Guam in 2024 and also leads Shimizu Technology, where software is built for organizations in Guam and beyond. He has worked at Spectrio and taught at Actualize.

The school and studio share a practical view of learning: understand the fundamentals, build useful things, explain your choices, and keep improving the work.

Learning beyond class

Real context, clear expectations.

Through Shimizu Technology, students can see how professional teams handle users, data, delivery, and support. Some graduates have practiced on real projects when active work and their readiness aligned.

Internships, contract work, and paid teaching roles depend on available projects and individual readiness. Completing a course or bootcamp does not guarantee any of them; a future opportunity will have its own eligibility and terms.
