Experience
RemoteWinBox
https://remotewinbox.comBuilt a network automation and orchestration system for MikroTik routers that makes monotonous tasks easier. It included working on automated firmware upgrades, mass configuration router pushes, speed tests, network health checks, historical and live data, user management for the whole network, and centralized auto-provisioning.
I worked on this project from its beginning at Thaea, where I am a CTO and one of the company founders. Initially, this was a platform for secure remote access to MikroTik routers. I was involved in various tasks, including designing and implementing the auto-provisioning system and using MikroTik's bandwidth testing protocol to write a MikroTik-specific speed test algorithm. Also, I handled an alerting system for the whole network, built a scalable router online status feature, and started leading a team of full-time developers almost a year ago.
