Platform foundations
Cloud architecture, Kubernetes, networking, identity, infrastructure as code, and sensible defaults for teams that need to move.
Infrastructure & DevOps Engineer
Fensius Musa
Aritonang
I design and operate cloud platforms that are easier to ship on, safer to change, and less surprising at 3 a.m.
- Based in
- Jakarta, Indonesia
- Focus
- Cloud, DevOps, SRE & Security
How I work
Infrastructure should make the product team faster, not give them another system to work around.
I work across cloud architecture, Kubernetes, deployment systems, observability, incident readiness, and security controls. The recurring job is turning a pile of services and manual steps into a platform people can understand and trust.
Capabilities
The work I tend to take on
Delivery systems
CI/CD, GitOps, progressive rollout patterns, rollback paths, and production deployment practices that leave an audit trail.
Reliability & cost
Monitoring, alerting, capacity planning, incident response, and pragmatic cloud-cost work without trading away resilience.
Security & compliance
DevSecOps controls, least-privilege access, operational documentation, and infrastructure preparation for regulated environments.
Selected experience
A career in systems that have to keep working
