About Me

Sergio Gallegos

I build software for industrial systems, drawing on 14+ years in controls and automation. My work as a Senior Engineer includes designing and integrating PLCs, HMIs, robotics, and vision systems for automated assembly machines.

That background shapes how I approach software: connectivity has to work with real equipment, data has to be useful to operators and other systems, and reliability matters long after the first successful demo.

Today, I’m focused on backend and product engineering for industrial platforms. My projects include a Rust EtherNet/IP library for Allen-Bradley PLCs and OpenWebHMI, an open-source HMI/SCADA prototype built with Rust and Python scripting.

My foundation is in Electromechanical Engineering. I’m currently pursuing a Master of Science in Software Engineering, with expected graduation in spring 2027, focusing on architecture, system design, and modern development practices.

Outside of work, I’m a father of two, a soccer fan, and someone who enjoys building systems, from machines to software.

Featured Projects

Software that connects industrial equipment to the applications built around it.

Rust EtherNet/IP

Connects backend applications to Allen-Bradley CompactLogix and ControlLogix PLCs through EtherNet/IP. Built in Rust, validated on real hardware, and available to Rust, C#, and Python developers.

  • Validated on real Allen-Bradley hardware: 5069-L320ERMS3 fw35 and 1756-L81ES fw37.
  • More than 5,000 crate downloads, plus NuGet distribution for .NET users.
