Summary
👤
Senior🎓
Top SchoolFred Larsen is a seasoned Software Architect based in Norway with over 25 years of hands-on experience designing robust, cross-platform systems in C, C++, C#, Java and Rust, and a decade-plus focus on cloud-native Java and microservice architectures. He has deep expertise in industrial protocols (OPC UA/DA, Modbus), high-uptime synchronization and communication layers, and has built production-grade connectors for OPC UA, MQTT/AMQP and Azure IoT. Fred pairs low-level optimization skills—demonstrated by contributions to the PJON embedded network protocol—with browser-based 3D visualizations (three.js/WebGL) for engineering workflows like PVT and pump vibration analysis. Comfortable across Windows, Linux and embedded platforms, he combines mathematical modeling and interpolation algorithms with pragmatic DevOps and agile practices to deliver scalable, maintainable systems. Colleagues rely on him for solving thorny integration problems and for architecting resilient data flows between field devices and cloud services.

Contributions summary:Fred primarily contributed to the PJON network protocol by making several key improvements. They pre-allocated buffers, moved functions to a global scope for broader use, and added `const` qualifiers to getters, indicating a focus on code optimization and maintainability. Furthermore, the user split the dispatch function into smaller parts and added an acknowledgment function for more flexible message composition, demonstrating expertise in refining core functionalities of the protocol. The addition of various strategies (Ethernet TCP/UDP and DualUDP) along with support for different platforms such as Linux and ESP8266 shows deep involvement in developing and integrating the PJON protocol.
