Surviving the Spike: How We Scaled Jakarta's Biggest Polytechnic Admission Exam for 440 USD
Lessons from building a resilient Moodle environment with Redis, NFS, Cloud SQL, and GCP Load Balancing
I architect infrastructure, deploy reliable systems, and keep networks secure. From bare-metal virtualization to automated monitoring, I build the foundation that applications run on.
Software is only as good as the infrastructure it runs on. Here is the toolbelt I use to ensure high availability, visibility, and security across the network.
Managing bare-metal hypervisors and containerized workloads for efficient resource allocation and isolated environments.
Routing, bandwidth management, and maintaining a Single Source of Truth for complex network topologies.
Keeping a pulse on system health through metrics, and managing distributed or high-throughput storage systems.
Writing internal tools to automate incident response workflows and securing organizational endpoints.
Real-world deployments that required getting hands dirty at every layer of the stack.
Architected and deployed a highly optimized Moodle instance designed to handle concurrent testing loads for 3,500 users. Required fine-tuning virtualization resources on Proxmox and strict database optimization to ensure zero downtime during critical examination windows.
Led the migration of an organizational internet login system to a centralized RADIUS infrastructure. Implemented PCQ on MikroTik routers to enforce strict, fair bandwidth management across the network, drastically reducing network congestion complaints.
Spearheaded the deployment and population of a NetBox instance to serve as the Single Source of Truth for all network and IPAM documentation. Transitioned the team away from fragmented spreadsheets to a structured, API-accessible database for infrastructure tracking.
In response to a large-scale phishing incident, developed a semi-automated password reset and ticketing pipeline using Node.js. This tooling allowed the support team to process the massive influx of compromised accounts rapidly while maintaining strict access controls.
