About Me

I am a seasoned Software Engineer with extensive experience developing backend, desktop, and embedded software for security, military, and medical applications using C++, Python, and Golang technologies. I support clients in architecture and technology definitions, protocol requirements, and software implementation, as well as team-leading. During my 16 years career, I have worked on creating multiple desktop applications, electronic equipment projects, and several IoT system projects.

Portfolio

Nylas (via UpStack)
Nylas (via UpStack)

Nylas securely powers email, calendar, and contacts integrations, so you don’t waste months building infrastructure. Our APIs unlock valuable insights from communications data, empowering companies to quickly launch email and scheduling solutions that drive more engaging customer experiences. Worked on the development of a backend system for E-Mail processing, collecting annotations to be used in a machine learning engine for automated email processing using Golang and GCP. Worked on software maintenance of core backend engine in Python.

Plastic Injection Machines Monitoring
Plastic Injection Machines Monitoring

Karcher Brasil is implementing Industrial IoT projects on its factory floor. The first project was to remote monitor its line composed of 8 plastic injection machines, delivering real-time production information. A system composed of a local data collection software and storage system was implemented. I was involved in project design and development. The project was successfully launched and is currently in operation. The result was monitoring the real-time operation of plastic injection machines on a factory floor using Industry 4.0 (IoT) technologies. Technologies used in the project: C#, OPC Protocol, MQTT protocol, Microsoft SQL Server.

Fiscal machine remote monitoring system
Fiscal machine remote monitoring system

Gertec is a Brazilian leader in retail devices products. SAT fiscal is a device ruled by the government, responsible to send real-time retail purchases to the government’s servers. Gertec is a manufacturer of SAT devices. We created a system responsible to get the device status and send it to a web cloud system, which shows the devices and consolidate information, detecting and alarming operation problems. Managed to achieve real-time monitoring Brazilian fiscal machines (SAT devices) installed in Point of Sales (POS) in retails. The system s detects problems with receipts and issue alarms in case of problems. Technologies used in the project: C++, Qt Framework, MQTT protocol, IBM Watson IoT platform, Python.

Surge discharge protection device remote monitoring system
Surge discharge protection device remote monitoring system

Balestro is a Brazilian company that manufactures electrical products. The company’s main product is a surge discharge protection equipment used in electric substations plants. The challenge was to create a device and a system to detect the quality of the surge discharge protection device remotely, without the need of a human to be close to the device for inspection. Managed to achieve real-time monitoring of surge discharge devices installed in electric substation plants. Based on an IoT device installed in the surge discharge protector device, it collects the data and detects problems, issuing alarms. Technologies used in the project: C#, MQTT protocol, InfluxDB, PostgreSQL.

 IoT Gateway for Trox Technik
IoT Gateway for Trox Technik

Hardware design and firmware development for IoT gateway used to add connectivity for air handling machines. Hardware designed using STM32 microcontroller, with Ethernet, WiFi and RS-485 support, and MODBUS and MQTT protocols. The operating system used in the hardware was NuttX.
