About

I dove into programming about 2 years ago when I was rethinking my path after earning my degree in Mechanical Maintenance Engineering, and what always sparked my interest was the power to create with code. I dove deep into several courses, and since then I cannot imagine a life without being a developer and bringing ideas to life through code.

What I'm looking for

Looking for a Backend developer role to expand my knowledge on building large scalable coding projects. I'm passionate about Backend Development, code design and create good user experiences. I'm sure that my knowledge of Testing Driven Development will ensure that I can create a good network of tests that, in addition to providing coverage to the code, will ensure that old functionalities will not be broken when a new feature is added to the project.
