About Filion
Hi! I'm Zdeněk, an engineer based near Ostrava, Czech Republic. Since university I've worked on the edge between computer networks and programming, and I keep using one to solve problems in the other. At IBM I wrote software to configure thousands of Cisco devices. For my own platform, I set up the servers, firewalls and load balancer myself.
I like problems that take digging. I'm detail-oriented, I enjoy tracing a fault to its cause, and I like explaining what I've found. I've taught CCNA and university courses on networks and SQL, and given product demos and training to partner companies.
Achievements

Built Property Flute, a meeting and voting platform for strata corporations, alone: from the first line of code to the cloud infrastructure. In production since 2021 with no failed meeting and no unplanned downtime. Largest client: 700 units.
2019
Traced a network loop causing a broadcast storm that had taken down three remote mine sites in northern British Columbia. Flew by helicopter to a mountain-top site to replace the faulty switch and built the recovery plan with senior management, often with no internet to look anything up.

2015
Surveyed Wi-Fi on site at international tire manufacturer's factories in Europe and India: measured signal, built heat maps, chose the equipment, then configured it and brought it live.
