Work Background
ClusterFull-Stack Engineer
Jan. 2025 - Apr. 2025Florianópolis, Santa Catarina, BrazilAt Cluster, I worked as a Full-Stack Developer focused on building scalable, data-driven web applications. I collaborated closely with designers and engineers to translate business requirements into responsive, intuitive user interfaces and robust back-end solutions. Key Contributions:
- Developed front-end interfaces using React and Zustand, ensuring clean code structure and maintainable state logic.
- Transformed Figma prototypes into responsive layouts with Tailwind CSS, adhering to accessibility and UX best practices.
- Built and integrated back-end services with Node.js (NestJS), enabling seamless communication between systems and external APIs.
- Created reusable front-end and back-end components to streamline development and improve consistency across the codebase.
- Actively engaged in planning and development cycles, providing input on technical feasibility, project estimation, and system behavior.
- Worked closely with the team to document and communicate implementation strategies and system behavior to support project alignment. Project Highlight:
Contributed to the development of a mashup application for Qlik Sense integrated with a Snowflake database, built for a major U.S.-based aerospace parts manufacturer. The solution delivered advanced analytics capabilities through an interactive web interface and supported real-time data exploration tailored to the client's operational needs.
LabTrans/UFSCFull-Stack Engineer
Jun. 2021 - May. 2024Florianópolis, Santa Catarina, BrazilAnalysis and development of a web system in the ICM (Maintenance Condition Index) project of the Transport and Logistics Laboratory (LabTrans) of the Federal University of Santa Catarina (UFSC). Problem Statement:
The ICM project, developed for the Brazilian National Department of Infrastructure and Transport (DNIT), aimed to create a system uses footage of federal highways to manage and maintain the condition of these roads. One of the core challenges during the development of the ICM-Web Application was a significant performance issue. The web application struggled under heavy user load, leading to slow response times, which threatened the overall efficiency and user satisfaction. Solution:
The ICM system comprised three main modules: the DNIT-ICM Desktop Application, the ICM-Mobile Application, and the ICM-Web Application. The ICM-Web Application, built with a Node.js back-end and a Microsoft SQL Server database, and a React.js front-end, provided highway managers with detailed reports and charts about road conditions. To address the performance issue, I conducted a thorough analysis of the codebase and identified inefficient database queries as the primary bottleneck. I addressed performance issues by optimizing inefficient database queries, implementing caching, and applying asynchronous processes to enhance efficiency. Result:
The optimizations significantly enhanced the application's performance, resulting in faster response times and a much smoother user experience, even under heavy loads. These improvements enabled highway managers to access critical information more quickly and efficiently, ensuring the system operated reliably during peak usage periods. This project solidified my expertise in Node.js and React.
High-Performance Geophysics Laboratory (HPG Lab)Systems Analyst | Software Engineer
Feb. 2019 - Jan. 2021Campinas e Região, BrasilI was hired by the High-Performance Geophysics Laboratory (HPG Lab) at the Center for Petroleum Studies (CEPETRO) of UNICAMP to develop a crucial project called "AWS Quota Manager". Problem Statement: HPG was facing significant issues with cloud cost control. Researchers were inefficiently using AWS resources, leading to much higher-than-expected costs. Managers had no automated tools to control usage and relied solely on AWS’s built-in reports, which lacked the necessary granularity and real-time insights. Solution: To address this, I developed AWS Quota Manager, a serverless application (Lambda) created from scratch using Python. This tool allowed managers to assign each user a monthly quota in US Dollars. It included alerts to notify users when they were nearing their quota, and if the quota was exceeded, the application automatically shut down all the user’s services and resources, ensuring that costs remained within budget. On the first day of each month, all quotas were reset to their assigned amounts regardless of the previous month’s usage. The application also provided managers with the ability to generate detailed reports and charts on cloud usage and user quotas, offering greater visibility and control over resources. Result:
The outcome of the project was a success, as the AWS Quota Manager effectively solved HPG's issue of cloud overspend. By automating quota enforcement and providing real-time alerts, it significantly reduced costs and ensured that researchers could use cloud resources more efficiently. Additionally, managers gained improved control and insights into cloud usage through detailed reports and charts, helping to keep research projects within budget without compromising operational efficiency.
