strengths // why us
Why CloudBloom.
Not spec-sheet skills — four muscles built by real incidents and long-running production systems.
STRENGTH · 01
Diagnose to deploy — solo capable
A LINE-driven traffic outage: root-caused, redesigned auto-scaling and caching, and delivered — solo. Same pattern with the first Magento rollout, self-taught then productized.
STRENGTH · 02
Security backed by real infra experience
From an academic authentication-security background to ISMS handover and MFA-relay attack forensics — we respond to incidents understanding why the attack worked.
STRENGTH · 03
Global team leadership
6 years as CTO of the Thai subsidiary — hiring in English, bridge-SE for the Vietnamese dev partner, and leading teams up to 30 engineers.
STRENGTH · 04
Fast on new technology
Built a LINE API platform when AWS Serverless was still new. Led enterprise R&D on generative AI at launch. Currently shipping production work with vibe coding.
process // how we work
Path to steady state.
Clear ownership from first call to steady-state operation.
01
Discovery
Frame the problem and constraints; scope what we can genuinely own.
02
Design
Architecture, security and operational design produced in parallel.
03
Build & operate
IaC-first implementation, with vetted partners where scale requires it.
04
Ongoing support
Ongoing advisory and incident response under retained contract.
