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. As a Site Reliability and DevOps Engineer, my focus is on building resilient foundations—whether that means scaling environments for thousands of concurrent users or optimizing bare-metal setups. I believe the best infrastructure is the kind nobody notices.
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.
My big, real-world deployments that required getting hands dirty at every layer of the stack.
Architected a highly optimized Moodle instance designed to handle concurrent testing loads for 4,500 users. Fine-tuned virtualization resources and database performance to guarantee zero downtime during critical campus examination windows.
Centralized organizational network authentication by migrating to a robust RADIUS infrastructure. Redesigned bandwidth management policies to ensure equitable resource distribution, drastically reducing network congestion complaints across the institution.
Spearheaded the transition from fragmented spreadsheets to a structured, API-accessible database. Deployed a centralized IPAM and DCIM system, streamlining infrastructure tracking and bringing order to complex network topologies
Developed automated incident response tooling using Node.js to handle large-scale security events. Built a streamlined password reset and ticketing pipeline that allowed support staff to rapidly secure compromised endpoints without bottlenecking daily operations.
