About me

Solving problems, giving access and making people's lives better through software craftsmanship. I consider myself a bar raiser and I'm often the go-to person for tough pull request reviews and for elegant code writing. Furthermore, I encourage good development practices by making meaningful code reviews and being test and fail fast oriented. Paving my way into mastering software development and leadership, while aiming to build systems and products that deliver value to all my stakeholders.
