## Professional Experience
1. **Infrastructure Engineer — REGtee Cloud (Independent Project)** (Apr 2026 – Present, Pontianak, ID):
   Architected sovereign PaaS/IaaS platform using Proxmox, KVM, and LXC to transform local bare-metal servers into scalable, enterprise-grade cloud environments. Engineered Zero-Trust network architecture with Single SSH Gateway & Fast Reverse Proxy (FRP) to bypass ISP CGNAT. Orchestrated asynchronous CI/CD pipelines utilizing Golang, Dagger, and Nixpacks. Designed distributed logical networks via OPNsense and OVN (projecting ~80% infrastructure cost reduction).
2. **Junior Backend Engineer — Chronicles-OJ (Online Judge System)** (Feb 2026 – Present, Pontianak, ID):
   Engineered critical backend endpoints for automated grading recalculation and robust data validation, ensuring strict scoring accuracy. Developed communication modules (feat/Announcement and feat/Clarification). Designed team-based capabilities tailored for UNTAN Informatics "Strategi Algoritma" course. Maintained strict PR workflows, passing rigorous code reviews from Senior Engineer.
3. **Infrastructure & DevOps Engineer (Homelab) — Personal Enterprise-Grade-like Infrastructure** (Jan 2025 – Present, Pontianak, ID):
   Assembled bare-metal server (Dual Xeon E5) and automated Proxmox provisioning via Terraform & Ansible. Hosted 24/7 workloads (custom IoT backends, game servers, tools) with custom ingress pipeline bypassing CGNAT. Cloudflared & Caddy HTTP/S routing, Go gateway + FRP. Hybrid virtualization with Alpine LXC & nested Docker. Granular VLAN isolation via OPNsense and Cisco managed switch.
4. **IoT Firmware & Backend Engineer — Kitasan Doorlock** (Dec 2025 – Feb 2026, Pontianak, ID):
   Programmed secure ESP32 firmware utilizing PROGMEM for SSL certificate (.pem) storage, integrating AS608 fingerprint reader with NTP time sync. Architected MQTT backend worker with multi-level device-to-database validation, endpoint whitelisting, and SSL-encrypted database operations. Real-time biometric template sync & access audit logs.
