What I'm looking for

Software Engineer and Developer specializing in building scalable REST APIs and high-performance backend systems. Proven track record of optimizing network efficiency by 90% and serving 10,000+ active users through Spring Boot, NestJS, and SQL. I leverage CI/CD pipelines, SonarQube, and automated data monitoring to build robust, maintainable platforms that drive operational efficiency.

I’m a Systems Engineer (UCEVA) and a Software Programming Technician (SENA). I support and develop internal platforms for multi-site business operations, with a strong focus on quality (CI/CD, SonarQube), automation, and performance optimization.

At Avidesa de Occidente, I supported and developed an internal multi-site IT ticket management platform with a database of 10,000+ users, including assignment of requests by location. I also implemented daily reports and comparative KPIs for operational monitoring, built a PDF signing workflow for travel expenses, and created an SSL status viewer for certificate monitoring.

In my projects, I developed Angular Tree, a Visual Studio Code extension that analyzes Angular components, templates, selectors, imports, and routing to generate an interactive component hierarchy tree. I also built a Spring Boot REST API for managing incidents and maintenance at UCEVA with role-based access control, JWT authentication, and data validation, alongside hands-on data analysis and visualization with Power BI.
