During October 2025, Ivan Garcia Harlouchet developed a data serialization feature for the flipoyo/MOLONARI1D repository, focusing on efficient sensor data handling in LoRaWAN environments. He implemented Protocol Buffers-based encoding and decoding in C and C++, enabling compact payloads and faster parsing of sensor measurements. This approach addressed the challenge of transmitting structured data over constrained networks by reducing message size and improving processing speed on embedded systems. Ivan’s work established a traceable and auditable codebase, laying the foundation for scalable data ingestion and future analytics. The depth of the implementation reflects strong skills in LoRaWAN, protocol buffers, and embedded systems.
