Tech stack

I've used so much technology that I sometimes forget what was actually applied on a project, so I gathered here every tool, language, and service I work with or have worked with.

Skills beyond code

Skills I've picked up along the way to build digital products that actually hold up.

Frontend development

Interfaces that combine modern design, accessibility, quality, and performance, always considering every way a person might use them.

Responsive design

Building systems with a mobile-first approach, so the user always gets the best usability experience on any device.

Software architecture

Structures designed so the product grows along with the business. DDD principles and engineering best practices for building scalable, organized, and sustainable architectures.

Agile methodologies

Applying agile practices such as Scrum and Kanban. Always thinking about structure and organization to deliver the most value, continuously and collaboratively.

Technical leadership

Leading multidisciplinary development teams with a focus on quality, DRY, code standardization, technical alignment, and mentoring.

Teamwork

Running collaborative projects with different user profiles, stakeholders, designers, and developers, promoting clear communication and solid results.

Interested in seeing these tools come to life?

After all, tools are only tools if they aren't used in a coherent way. They're only the start. What really matters is the product this becomes for a real person. Check out some of these builds on the projects page.
