Some of the projects I’ve worked on, from company systems to simple websites.

Office Network Optimization — PT Adhitama Mitra Nusantara
Recent

01 · PT Adhitama Mitra Nusantara

Office Network Optimization

The office used to run on three ISPs, each on its own default ISP modem with a different Wi-Fi name. Ping was often high, and since every spot was a separate network, you couldn’t print after moving to another room. I rebuilt it around a MikroTik RB5009UG+S+ with three ISPs (up to 300/500/100 Mbps) and four Ruijie EW3000GX-PRO Wi-Fi 6 access points on one SSID. Office PCs get 50 Mbps each via ISP A, other devices 30 Mbps each via ISP B, apps are routed to a specific ISP, YouTube has its own line, the printer works from anywhere, and failover kicks in when a line drops.

Plus WhatsApp automation.
