My Journey
May 9, 2022 - Present
DevOps Engineer
PT Global Tiket Network
Jakarta, Indonesia
- Architected and managed 160+ production and development environments for tiket.com, ensuring 99.9% uptime and optimal resource allocation across Java Spring, React, and Go-based services.
- Engineered a sophisticated Kubernetes auto-scaling solution that reduced infrastructure costs by 60% during tiket.com's high-traffic OTW events while maintaining seamless user experience for 10+ million users.
- Spearheaded the containerization migration initiative, transitioning VM-based services to Kubernetes, resulting in 40% reduced operational costs and 35% improved application performance.
- Designed and implemented a comprehensive Infrastructure as Code (IaC) strategy using Terraform, reducing provisioning time by 75% and enabling rapid scalability during peak traffic periods.
- Orchestrated and optimized CI/CD pipelines using Jenkins, implementing automated testing and deployment protocols that reduced release cycles from days to hours.
- Developed an internal developer portal that streamlined service catalog access and automated service creation, increasing developer productivity by 30% and reducing onboarding time for new team members.
- Provided expert-level technical troubleshooting support, collaborating with development teams to diagnose and resolve critical production issues, reducing MTTR (Mean Time To Resolution) by 45%.
- Led cross-functional cost optimization initiatives across multiple verticals, implementing resource rightsizing and scheduling strategies that reduced overall infrastructure costs by 40% while maintaining service reliability.

Self-Directed Technology Research & Development
Bandung, Indonesia
- Designed and operate a comprehensive enterprise-grade homelab environment serving as a testing ground for emerging technologies and proof-of-concept implementations that directly enhance professional capabilities and inform infrastructure decisions at scale.
- Architected a fully virtualized infrastructure using Proxmox hypervisor managing 15+ virtual machines across multiple VLANs, implementing high availability clustering and automated backup strategies that mirror enterprise best practices and serve as a testing environment for production deployment strategies.
- Engineered comprehensive monitoring and observability infrastructure using Prometheus, Grafana, and custom alerting systems, providing real-time insights into system performance and resource utilization across heterogeneous environments, resulting in 99.8% uptime for critical home services.
- Configured and optimized MikroTik networking equipment including advanced routing protocols, VPN tunneling, and network segmentation strategies, creating isolated testing environments that enable secure experimentation with network topologies before implementing similar solutions in production environments.
- Developed and maintained IoT management platform using Home Assistant, integrating 50+ devices across multiple protocols (Zigbee, Z-Wave, WiFi) with custom automation scripts and security monitoring, demonstrating skills in edge computing and device management that translate directly to industrial IoT implementations.
- Implemented production-grade Kubernetes clusters using K3s lightweight distribution, managing containerized applications across multiple nodes with automated scaling, persistent storage management, and service mesh integration. This environment serves as a testing ground for complex orchestration scenarios including stateful applications, custom resource definitions, and GitOps deployment workflows that directly inform production Kubernetes strategies in enterprise environments.
