Full-stack developer and technical lead, with over 15 years of experience. I work on various business web projects (SaaS, CRM, E-commerce, Desktop/Mobile Applications), from scoping to production, with a solid foundation in Laravel, Vue.js, and Node, as well as DevOps/CI-CD expertise. I also integrate modern Artificial Intelligence solutions, including the design of RAG (Retrieval-Augmented Generation) systems and connection to LLMs to enhance your applications. Equally comfortable coding and leading a team: I bring autonomy, versatility, and a focus on quality all the way to production.
