PLATFORM ENGINEERING
Platform Engineering & Internal Developer Platforms
Reduce infrastructure complexity and create a safe, fast delivery foundation for product teams.- Developer platform
- CI/CD
- Operations automation
WHY JJGO
Build the platform as an internal product—not another technology project.
Experience designing and operating DBaaS, KaaS, cloud portals, and AI platforms brings developer experience and operational reliability into one view. The goal is not more infrastructure; it is lower cognitive load and faster delivery for product teams.- About 200
- Kubernetes clustersDesigned, built, and operated through NCSOFT KaaS
- 1,000+
- Cluster nodesAcross AWS, GCP, OpenStack, and bare-metal environments
- 15+
- Cloud servicesIntegrated into an internal micro-frontend cloud portal

EXPERTISE
How I can help
Platform as a Product
Treat developers as customers and shape the platform vision and backlog around journeys, pain points, and adoption measures.
Reference Architecture
Design boundaries and integration across portals, service catalogs, IDPs, and observability within technical, security, and cost constraints.
Golden Path & Automation
Implement safe defaults and self-service automation from project creation through build, test, deployment, and observability.
SRE & Governance
Operate speed and reliability together through SLOs, error budgets, policy automation, cost visibility, and a clear support model.
WHAT YOU GET
What we build together
Platform product strategy
A clear definition of platform customers, value proposition, boundaries, priorities, and success measures tied to developer journeys and organizational goals.
Reference architecture & golden path
A working self-service path connecting portal, catalog, CI/CD, IaC, and observability for real product teams.
Operating & governance model
A sustainable structure for platform responsibilities, team autonomy, SLOs, policy automation, support, and cost.
WHEN TO START
When to start
- 01
Every team builds, deploys, and observes differently, increasing duplicated work and operational load.
- 02
Cloud, security, and infrastructure complexity are increasing cognitive load and slowing product delivery.
- 03
The organization needs stronger standards, cost efficiency, and reliability without taking autonomy away from developers.
PROCESS
How we work
Scope and timeline are adjusted to your context.- 012–3 weeks
Assess
Measure wait time, repetitive work, and reliability or security bottlenecks through developer interviews and delivery-flow analysis.
- 021–2 weeks
Prioritize
Select the first platform product area using developer value, operational impact, and implementation cost.
- 036–12 weeks
Build
Create a golden path with a real product team, including portal, templates, pipelines, and observability.
- 04Ongoing
Productize
Run the platform backlog using adoption, lead time, deployment, recovery, and feedback measures.
