Hello! 👋 I’m Alef, a Senior Full Stack Engineer with 10+ years of experience building scalable, high-performance web applications for global companies, with a strong focus on frontend architecture and e-commerce platforms.
I have hands-on experience with modern technologies such as Vue, React, Nuxt, TypeScript, GraphQL, Node.js, Nest.js, Tailwind CSS, and headless commerce architectures. Throughout my career, I’ve worked extensively in complex web software environments, integrating and scaling platforms like Magento (1 & 2), Commercetools, SAP Commerce, Oracle Commerce Cloud, Prestashop, Shopify and VTEX.
Across different projects, I’ve helped teams improve performance, scalability, and developer experience by designing reusable frontend patterns, optimizing data-fetching strategies, and contributing to open-source projects, including the open-source core integrations at Vue Storefront used by companies worldwide.
In addition to my technical skills, I’m known for my clear communication, collaborative mindset, and ability to work in fast-paced, distributed teams. I’ve worked with international teams across different time zones and cultures, always focusing on delivering value and building maintainable solutions.
I’m currently based in São Paulo, Brazil, with proficient English communication and writing, and I’m open to remote opportunities and relocation. I’m especially motivated by projects that value innovation, autonomy, and continuous learning.
