Arthur Fetzner

Professional Profile

Software developer driven by the challenge of making complex systems communicate seamlessly. With over 2.5 at Elipse Software, I specialize in building communication drivers that bridge the gap between industrial equipment and supervisory systems, transforming raw protocols into reliable, production-ready solutions.

My expertise centers on C/C++ systems programming, where I've worked on 28+ projects spanning 23+ protocols like BACnet, MQTT, OPC A&E, DNP 3.0, and Modbus, contributing to their development, maintenance, and feature implementation. Each project involves mastering protocol specifications, debugging edge cases, and ensuring rock-solid performance in real-world industrial environments. I leverage the full Windows development stack (STL, MFC, COM, ATL, and Win32 SDK) to build native solutions that integrate deeply with existing infrastructure.

Beyond industrial automation, I bring full-stack development capabilities to the table. Whether architecting backend APIs with Node.js and Flask, crafting responsive interfaces with React, or designing database schemas for performance, I approach web development with the same rigor I apply to systems programming. This versatility has enabled me to contribute to projects ranging from local commerce marketplaces to internal Sectoral Intelligence platforms.

At the core of my work is a commitment to engineering excellence. Writing maintainable code, conducting thorough code reviews, creating comprehensive documentation, and building systems that stand the test of time. I thrive on continuous learning, whether diving into a new protocol specification, exploring emerging technologies, or refining my craft through deliberate practice.
