Leonardo Altamar

I’m a Full Stack Developer with five years of experience building scalable web applications, backend services, APIs, and user-focused interfaces. My main technologies include JavaScript, TypeScript, React, Angular, Vue.js, Node.js, Express, NestJS, PHP, Laravel, PostgreSQL, MySQL, and MongoDB. I also have experience with AWS, Azure, Docker, CI/CD, automated testing, and third-party integrations such as Stripe and Twilio. At AIforBusiness, I worked across the frontend and backend to improve application performance, develop reusable components, and build reliable API integrations. One of my main achievements was optimizing a large-scale e-commerce platform, reducing its loading time by 50% and helping increase conversions by 20%. I also performed code reviews across five projects and introduced practices that significantly reduced recurring errors and improved maintainability. I’ve worked on an AI-powered video-generation workflow, implementing frontend-to-backend communication, asynchronous job tracking, result processing, and failure handling. For my next role, I’m looking for a senior remote Full Stack or Backend position where I can own features end-to-end, solve meaningful technical problems, and collaborate with an international product team.
