Background

I'm a software developer with over two decades of hands-on experience across backend development, industrial systems integration, and IIoT cybersecurity. Based in Ottawa, Ontario, I've spent the bulk of my career building secure, high-performance solutions for critical infrastructure — from hydroelectric plants to oil & gas facilities.

My core stack is C# .NET, but my background spans Java, Python, SQL, and Delphi. Deep expertise in SCADA/OPC systems, time-series databases, and secure networking (VPN, firewalls, data diodes).

Open to relocation. Available for remote, hybrid, or on-site roles.
