Code Quality: Maintained application stability through comprehensive unit testing of core features and critical functionality. Key Results (Google Lighthouse): ✅ 100/100 SEO ✅ 100/100 Accessibility ✅ 100/100 Best Practices ✅ 97/100 Performance

Landing Page Development Responsibilities: * Conversion-Focused Development: Built high-converting landing pages using Conversion Rate Optimization (CRO) principles, ensuring effective visual hierarchy for headlines, social proof, and calls-to-action (CTAs). * Performance Optimization: Applied aggressive performance optimizations to minimize load times and reduce traffic loss from paid advertising campaigns. * Responsive Design: Implemented a mobile-first approach, delivering a seamless user experience and maximizing lead retention across mobile devices. * Scalability: Developed modular and reusable page structures, enabling efficient replication and customization for multiple products within the portfolio. Results: * Delivered landing pages optimized for paid traffic, helping maximize campaign ROI. * Reduced navigation friction, creating a more intuitive and streamlined purchasing journey. Google Lighthouse Scores: ✅ 100/100 SEO ✅ 99/100 Performance ✅ 97/100 Accessibility ✅ 96/100 Best Practices

Backend development for an urban management platform, contributing to the creation of solutions focused on city data organization and analysis. Key responsibilities: * Developed backend APIs and services following best practices for maintainability, scalability, and performance * Modeled and optimized PostgreSQL databases * Built administrative dashboards for real-time data visualization with a strong focus on usability * Implemented performance improvements to support large volumes of concurrent data processing * Assisted with cloud infrastructure configuration and maintenance on AWS (EC2, S3, and Lambda) * Used Git for version control and team collaboration Technical highlight: * Implemented a geospatial clustering strategy using geohashing to optimize incident-report processing, reducing database load and improving application response times Results: * Contributed to the delivery of a stable platform with data-driven dashboards that support urban operations and decision-making

During my Computer Science degree at Estácio, I have consistently sought opportunities to apply academic knowledge to real-world challenges and emerging technologies. One of the highlights of this journey was being invited by a professor to deliver a lecture on Backend Development for E-commerce. During this session, I shared software architecture best practices and practical insights into current industry expectations and market demands.
