The in-house server cluster that runs Grendene's factory systems. Its five servers host more than 30 internal apps, 10 of them dashboards that monitor the factory floor, along with the company's data pipeline and a private AI assistant that runs on local hardware. When something breaks, an automated check on each server repairs network, storage and container failures on its own.
Website for MICROTECH, an Apple repair shop. Its iPhone repair quote tool shows the customer an estimated price and passes the conversation to WhatsApp.
A complete company data platform, similar to what Databricks offers, that runs on local servers without depending on a cloud provider. It pulls data in from other systems, both in scheduled loads and as changes happen, then cleans and organizes it in stages until it is ready for reports. Quality checks run automatically, bad records go to a quarantine area, and every number can be traced back to where it came from.
Web system that organizes production activities in Grendene's tooling department. Each user signs in and sees what their role allows. I built both the back end and the screens.
Extensions for Grendene AI, the company's private AI assistant, which runs on its own servers. They let the assistant read live web pages, open spreadsheets and data files, and work with text in Portuguese. The assistant answers from a private knowledge base and remembers each conversation.
Monitoring device built on an Arduino. It reads sensors and shows the readings live on a web dashboard.
Interactive teaching app that shows how the logic inside a processor works, through a simulated alarm system. Made as class material for the Systems Analysis and Development course at Faculdade Anhanguera Sobral (April 2024).
Web app for requesting product samples. The screen shows the product image next to a form that checks the request before it is sent.
AI assistant for production planning and control. Staff ask questions in plain language and get answers from the factory's production data, with user accounts and login.
Back end for an accreditation and credentialing system, written in C#, with the business rules kept apart from the technical details.
Mentors the team's analysts and spreads good software and data practices at Grendene.
Writes documentation, keeps agile teams aligned and turns business needs into technical requirements.
Works on every layer of a product, from the screens to the systems behind them and the data, as each project needs.
Business Administration degree and a People Management postgrad; uses KPIs and metrics to support business decisions.
I'm a Software Engineer and Data Engineer at Grendene S/A, one of Brazil's largest footwear makers. I joined in 2010 as a production helper and moved into software and data in 2019. Today I build the internal systems teams use every day and the data pipelines behind the company's reports, which process millions of records a day.
I also run the servers all of this lives on, inside the factory, including a private AI assistant that runs on the company's own hardware. I have a degree in Business Administration and postgraduate degrees in People Management and Software Engineering, which helps me work between business and technical teams.
