About

I am a software developer with over 15 years of experience as a Full Stack Developer, specializing in designing and implementing robust, scalable applications. I have strong backend and frontend skills and have worked on integrations with enterprise systems such as SAP and Salesforce, always with a focus on quality, security, and performance.

I have led cross-functional teams and managed end-to-end projects across Latin America for clients like Citi, Nestlé IT LATAM, and Falabella, embracing agile methodologies (Kanban/Scrum) and modern tooling. My technical toolkit includes Java, .NET/C#, Ruby on Rails, Blazor, React, and a broad set of databases and APIs, with a passion for delivering reliable software that drives business value.
