About

I have spent my career designing, delivering and modernizing enterprise software for government, media, logistics and publishing. I have led cross-functional teams of up to 20 engineers, mentored developers, run technical interviews and worked daily with stakeholders across the USA, Europe and the Middle East.

My focus is cloud-native delivery on Microsoft Azure: microservices, CI/CD, infrastructure as code and clean, maintainable .NET and Angular codebases. I balance technical strategy with business goals so the result is secure, scalable and easy to own.

Outside client work I run VTOXI, where I build my own products, from browser tools to IoT devices on Raspberry Pi, ESP32 and Arduino.

Dry wellPump runs but the tank never fills

    What happens if nobody stops the pump? Switch to On and watch. In this demo, manual On ignores the stop level.

    A simplified model of AquaSync's logic: separate start and stop levels so the pump does not chatter, and a safety cutoff when it runs too long without filling. Thresholds here are for the demo.
