I mainly carry out activities focused on technical leadership and project management, having closer contact with the client, but at the same time supporting the technical team and creating solutions for the most robust demands.

Among the solutions created, one that stands out is a converter of NB-IoT devices to LoRaWAN, the system creates a bridge between these two technologies, so that the transformation is undetectable for the device and for the system that performs the LoRaWAN processing, providing a way to abstract multiple parts that would be necessary for both LoRa and NB-IoT processing.

• Frontend: React, Angular, Vue
• Mobile: Flutter, React Native, Swift
• Databases: PostgreSQL, Oracle, MongoDB

I played a key role in refactoring IoT device management systems by designing a new workflow to efficiently handle the high volume of simultaneous data provided by devices. This involved implementing queues, establishing clear separation of responsibilities, and optimizing processes to transfer only updated values. These enhancements drastically reduced processing time from hours to mere seconds during peak loads and significantly lowered system resource usage.

I also enhanced the connectivity architecture for devices, incorporating technologies like LoRaWAN, NB-IoT, and others. These upgrades provided greater control and improved visibility into the entire data transmission flow, resulting in a more reliable and transparent system.

Additionally, I transitioned into technical leadership and team management roles. My responsibilities included coordinating activities, managing cross-functional teams, supporting the implementation of new features, and resolving both client and technical impediments. This work spanned multiple projects across diverse sectors and technologies, ensuring alignment and efficiency in complex environments.

I have worked on the development of systems for the energy sector, IoT and its management, mainly using the LoRaWAN protocol. My responsibilities include both backend and frontend development, as well as mobile applications. Additionally, I have dealt with activities related to relational and non-relational databases.

After completing my IT technician course, I completed an internship working as a developer. My main focus was to implement a management system for beauty salons, which supported payments and provided easy administration and control.
