Announcing my new Tools Hub
A curated collection of utilities for DevOps, Platform, Cloud and Software Engineers

The Inspiration
When I first started my career, I began with CCNA training. Networks were what got me into systems engineering and then later on DevOps and Platform Engineering. Over the years one thing became clear very quickly: every platform project starts with network planning. I find myself over and over using visual subnet calculators available online.
Whether you are building a small on-premise setup or a massive cloud architecture, you inevitably deal with subnets, IP ranges, and CIDR blocks. And it’s not just a one-time task. Every now and then, we still need to go back to subnet planning whether it’s for modifying existing networks, adding new subnets, or carving out space for a new service.
That recurring need is what drove me to build these tools. I wanted a reliable, easy to use set of utilities that I could use myself to streamline these tasks.
The Tools Hub
The Tools Hub is a Single Page Application (SPA) designed to be fast and helpful. You can find detailed guides and workflows in the documentation.
It currently features:
Cloud Subnet Calculator
Calculate and visualize subnet divisions for cloud environments. Supports AWS, Azure, and GCP.
Azure VNet Designer
Design multi-VNet hub-and-spoke topologies across Azure regions. Export to Terraform and Bicep.
I’ve built these tools because they are what I use, and I hope they will be just as useful to you in your daily work.
