Experience

Clínica Remota, Remote Monitoring of Clinical Assets

https://app.clinicaremota.com

An IoT platform to monitor essential clinical assets, such as CT scans and MRI machines, tracking important variables to detect issues and anomalies in clinics, helping businesses avoid losses due to unnoticed failures.

I fully designed the solution, applying concepts of clean architecture and TDD to make it reliable and robust, bringing confidence to the team in every delivery. I also developed the front end using Vite, React, and TypeScript as a PWA and implemented key features, such as data visualization using Chart.js and interactive maps to show assets and their status using Google Maps. I built the back end using Node.js, TypeScript, Express.js, and PostgreSQL and integrated with 3rd-party APIs, such as GCP, OneSignal, and AWS.

Additionally, I designed and implemented the delivery and deployment using GitHub Actions and AWS services, such as EC2, S3, and CloudFront CDN.

Muninn, an IIoT Platform

This platform was created to bring Industry 4.0 to small- and medium-sized businesses through data collection and analysis. As a full-stack developer, I developed algorithms to analyze the collected data. Also, I implemented dashboards and interfaces to deliver our users the data they needed in the best possible way.

NÓS Nosso Olhar Solidário, a Donation App

https://play.google.com/store/apps/details?id=org.projetonos&hl=pt_BR&gl=US

NÓS is a donation app maintained as an extension project by the Federal University of Technology - Parana (UTFPR) created to match donators and institutions that needed help during the COVID-19 pandemics. Collaborating with a team of developers and designers, I worked as a volunteer to optimize the structure and performance of the app, which was only an MVP at that point, and create new features.
