Network Architect / ISP Systems Builder / Infrastructure Engineer
Membangun, mengoperasikan, dan mengembangkan infrastruktur ISP. Fokus pada operational control, automation, security, dan observability — sistem yang benar-benar berjalan di production.Building, operating, and scaling ISP infrastructure. Focused on operational control, automation, security, and observability — systems that actually work in production.
Sejak 2017, saya bekerja di industri ISP — mulai dari operasional harian, troubleshooting jaringan, hingga merancang sistem yang menghilangkan pekerjaan repetitif dan meminimalkan human error.
Since 2017, I've been working in the ISP industry — from daily operations, network troubleshooting, to designing systems that eliminate repetitive work and minimize human error.
Saya percaya engineer seharusnya membuat keputusan, bukan mengulang-ulang task yang sama. Sistem yang baik bekerja tanpa suara — infrastruktur yang benar tidak terlihat sampai ada yang salah.
I believe engineers should make decisions, not repeat the same tasks. Good systems work quietly — proper infrastructure is invisible until something goes wrong.
Engineer bekerja melalui sistem, bukan langsung ke perangkat
Engineers work through systems, not directly on devices
Log adalah aset, data mendorong keputusan operasional
Logs are assets, data drives operational decisions
Menghilangkan tugas repetitif dan human error
Eliminating repetitive tasks and human error
Keamanan bukan opsional, tapi fondasi
Security is not optional, it's foundational
Setiap tool dibangun dari kebutuhan operasional nyata dan membentuk ekosistem terintegrasi untuk operasional ISP.Each tool is built from real operational needs and forms an integrated ecosystem for ISP operations.
Bot Telegram untuk monitoring redaman interface SFP pada switch dan router, termasuk status link optik di lapangan. Nama "BotLinkMaster" dipilih karena perannya sebagai pengendali visibilitas link — "Master" merepresentasikan otoritas terhadap kondisi fisik link: redaman, status, dan kesehatan jalur optik.
Telegram bot for monitoring SFP interface attenuation on switches and routers, including field optical link status. Named "BotLinkMaster" for its role as link visibility controller — "Master" represents authority over physical link conditions: attenuation, status, and optical path health.
View RepositoryTool diagnosa jaringan yang fokus pada ping, traceroute, dan DNS lookup untuk troubleshooting harian. Nama "PingTD" berasal dari Ping, Traceroute, Diagnose — pendek, teknis, dan langsung ke inti masalah. PingTD bukan sistem monitoring besar, tapi alat tajam untuk menemukan akar masalah jaringan secara cepat.
Network diagnostic tool focused on ping, traceroute, and DNS lookup for daily troubleshooting. Named "PingTD" from Ping, Traceroute, Diagnose — short, technical, straight to the point. PingTD isn't a large monitoring system, but a sharp tool for quickly finding network root causes.
View RepositorySistem penyimpanan log dan audit yang rapi, tenang, dan terstruktur. Nama "Leuit" diambil dari konsep lumbung — tempat menyimpan hasil dengan aman. LeuitLog berfungsi sebagai lumbung kejadian: log dikumpulkan dan disimpan agar bisa ditelusuri saat dibutuhkan, bukan untuk menciptakan kebisingan.
A clean, calm, and structured log storage and audit system. Named "Leuit" from the concept of a barn — a place to store results safely. LeuitLog serves as an event barn: logs are collected and stored for tracing when needed, not to create noise.
View RepositoryGateway untuk manajemen dan observabilitas OLT, menggabungkan SNMP dan CLI secara terkontrol. Nama "GETOLS" menegaskan fungsinya sebagai gerbang, bukan pengganti OLT — lapisan aman untuk monitoring, maintenance ringan, dan visibilitas tanpa merusak arsitektur asli perangkat jaringan.
Gateway for OLT management and observability, combining SNMP and CLI in a controlled manner. Named "GETOLS" to emphasize its role as a gateway, not an OLT replacement — a secure layer for monitoring, light maintenance, and visibility without disrupting the original network device architecture.
View RepositoryPolicy-aware DNS resolver, bukan sekadar DNS forwarder. Nama "Semar" diambil dari tokoh penjaga keseimbangan: tenang, bijak, dan tidak reaktif. SemarDNS berperan sebagai otak kebijakan di layer DNS, mengatur resolusi berdasarkan aturan dan konteks — karena DNS adalah core infrastructure yang tidak boleh ceroboh.
Policy-aware DNS resolver, not just a DNS forwarder. Named "Semar" after the guardian of balance: calm, wise, and non-reactive. SemarDNS acts as the policy brain at the DNS layer, managing resolution based on rules and context — because DNS is core infrastructure that must not be careless.
View RepositoryConfiguration Storage System — source of truth untuk sistem dan perangkat jaringan. Nama "Leuit" tetap digunakan karena maknanya sama: lumbung. Namun konteksnya berbeda — LeuitCSS adalah lumbung konfigurasi. Konfigurasi diperlakukan sebagai aset utama, disimpan secara immutable dan read-only, agar semua sistem mengacu pada satu kebenaran yang sama.
Configuration Storage System — source of truth for systems and network devices. Named "Leuit" for the same meaning: barn. But the context differs — LeuitCSS is a configuration barn. Configurations are treated as primary assets, stored immutably and read-only, so all systems refer to the same single truth.
