Network device simulator
Emulates Cisco, Juniper and Nokia NETCONF devices from their YANG models and mounts them on an OpenDaylight controller. Developers and testers get virtual devices with browser-based SSH, so they don't wait for hardware.
Test execution portal
A web portal for running sanity, feature and regression suites, with testbed management, run history and a built-in log viewer.
Protocol simulators
A Profinet traffic CLI in Golang, and a SCADA T104 packet library for building and parsing traffic. The SCADA proof of concept earned a Spot Award.
Hobby projects
TCP analyser with CLI and GUI, and an Android finance tracker, plus a few small command-line tools. The source is private for now. I'm preparing downloadable builds, including an APK for the Android app, and I'll add links here as each one is ready.
