A small studio, on purpose
We do not scale beyond the cohort sizes our mentors can teach properly. The day we cannot read every architecture write-up is the day we stop opening new seats.
Five people, in a fourth-floor room above Eonju-ro.
Nimbus Forge Academy is a small cloud architecture studio above Eonju-ro in Gangnam. We run cohort-based programmes, scenario-driven labs, and private team workshops with the working architects whose names appear below. The studio has five permanent staff, never more than twelve cohorts running at once, and a stated preference for honest first calls over high-velocity enrolment funnels.
Four principles we hold to
Honest before consultative
If a course is wrong for you, we say so on the first call. We would rather lose an enrolment than enrol someone into a programme that wastes their next eight weeks.
Real artefacts, real failure modes
Every lab is built from a real production story — most often one we collected during a clinic engagement. We rewrite a third of the lab catalogue every year for this reason.
Refunds you can read in a coffee break
Our Refund & Cancellation page is short and specific. The mechanics matter less than the principle: we should not keep tuition for a course you did not get.
Who you actually meet
The five names below are the studio. There are no anonymous mentors and no third-party contractors. If a course brochure mentions “a working architect”, it is one of these four.
YP
Academy Director
Yejin Park
Yejin opened the studio after a decade of designing landing zones for telco and logistics platforms across Seoul and Singapore. She owns the curriculum direction and personally interviews every cohort applicant before kickoff week.
Focus: Cloud landing zones, governance design
DH
Lead Cloud Architect
Daeshik Han
Daeshik runs the architecture review clinics and sits in on every Saturday lab session. He keeps a running notebook of failure modes from real client engagements that get rewritten into new lab scenarios each quarter.
Focus: Multi-region resilience, cost-aware patterns
MC
Curriculum Designer
Mira Eun-bi Cho
Mira translates messy production stories into structured weekly modules. Before joining the studio she ran a developer relations programme that shipped over 80 hands-on workshops, and she still drafts every learner workbook by hand.
Focus: Lab design, syllabus structure
JL
Technical Mentor
Junseok Lim
Junseok pairs with learners during evening lab hours and reviews architecture write-ups with a kind, exacting red pen. He spent six years on a platform engineering team responsible for around 400 microservices.
Focus: Kubernetes operations, incident response
HS
Student Success Manager
Hyojin Seo
Hyojin keeps cohort schedules sane and is usually the first person an applicant speaks to. She tracks each learner from intake through certification week and is honest with anyone who is signing up for the wrong reasons.
Focus: Cohort logistics, learner coaching
A short timeline
- 2019
A workshop becomes a studio
Yejin runs a one-off Saturday workshop in Mapo-gu that fills three times. By autumn, the first formal Cloud Foundations cohort kicks off in a borrowed lecture room.
- 2022
The clinic format opens
After repeated requests for a private review version of the cohort programme, the Architecture Review Clinic launches with a fixed two-day structure and a written critique deliverable.
- 2024
The full nine-programme catalogue
Multi-cloud, AWS resilience, GitOps, and the Azure Expert Track join the catalogue. The 2024 calendar runs 38 cohorts and 14 private engagements.
