About the harbor
Circuit Harbor Academy began as a cramped weekly meetup above a Gangnam print shop: people brought boards, shared power supplies, and argued politely about DMA. We formalized into cohorts when employers asked for repeatable onboarding—not slideshows, but repeatable labs with receipts.
Today we still optimize for small groups, moderated community channels, and mentors who actively ship. We are not a generic bootcamp marketplace; we publish scope limits because respect for learner time matters more than funnel volume.
Principles
- Telemetry stories beat vanity metrics.
- Quality standards conversations belong early, not as a surprise gate at the end.
- Remote participants get the same lab handouts, not a trimmed shadow syllabus.
- Community moderation is part of pedagogy, not an afterthought.
Timeline
- 2019 — First public firmware teardown nights in Seoul.
- 2022 — First paid cohort with published hardware BOM and refund policy.
- 2025 — Community archive opened for alumni-written field notes.
Team

Embedded Systems Mentor
Prefers oscilloscope screenshots in bug reports and teaches students how to narrate them to cloud peers.

Evelyn Cho
Cloud Solutions Mentor
Designs contract tests that fail loudly before JSON fields drift; runs Tuesday office hours KST.
Mateo Silva
Curriculum Designer
Maps labs so each week has a reversible checkpoint; allergic to single giant drop weekends.
