What I'm looking for

I’m looking for a team working with Agile/SCRUM where I can build maintainable full-stack features, collaborate cross-functionally, and strengthen database-backed solutions—always using SOLID, DRY, and Clean Code to support scalability and performance.

I’m a Data Systems Technologist with experience in Full-Stack Development, focused on building responsive front-end applications with AngularJS and React, and implementing scalable back-end solutions with JavaScript and SQL/PostgreSQL. I bring a strong foundation in database administration and requirements analysis, and I apply Agile/SCRUM to deliver efficient solutions.

I follow SOLID principles, DRY practices, and Clean Code standards to keep projects maintainable, scalable, and readable. I enjoy designing software that’s easy to extend, test, and collaborate on within cross-functional teams, from front-end user-facing features to back-end performance and data management.
