Building scalable web applications with React, Node.js, and Automated Testing strategies.
Hi, I'm Leandro. Full Stack Engineer & Quality Advocate
I build scalable web applications with React, Node.js, and TypeScript. Unlike traditional developers, I integrate Automated Testing (Jest/Selenium) into my workflow to ensure robust, bug-free software delivery.
Problem Solver
I thrive on algorithmic challenges. Recently achieved a 93% score in the Codility Technical Assessment, demonstrating my ability to deliver efficient and optimized solutions under pressure. I don't just write code; I solve business problems.
High Standards
I write code that is clean, maintainable, and testable. My workflow includes Clean Architecture principles and strict adherence to ISO/IEC 25000 quality standards. I believe that technical debt should be managed, not ignored.
Ownership
I take full responsibility for the product lifecycle, from the first line of code to deployment. I communicate proactive solutions and leverage tools like GitLab CI/CD to ensure smooth collaboration and reliable delivery.

Modern Frontend Engineering
I build responsive and performant user interfaces using React, TypeScript, and Next.js. I focus on creating intuitive experiences with pixel-perfect attention to detail, leveraging Tailwind CSS for modern styling and state management for complex logic.
Scalable Backend Architecture
I design robust server-side logic using Node.js, NestJS, and Express. My backends are built with Clean Architecture in mind, managing SQL (PostgreSQL/MySQL) databases efficiently and exposing secure RESTful APIs ready for scale.
Automated Software Testing
I don’t just ship code; I guarantee it works. I implement comprehensive test suites using Selenium, Jest, and Cypress. My approach covers Unit, Integration, and E2E testing to detect bugs early and ensure a bulletproof user experience.
