Background

I'm a software developer with over two decades of hands-on experience across backend development, industrial systems integration, and IIoT cybersecurity. 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, with a background spanning Java, Python, SQL, and Delphi. Deep expertise in SCADA/OPC systems, time-series databases, and secure networking — VPN, firewalls, and data diodes.

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