    More than ten years of experience working with programming, specifically Java web. I started with JSP and evolved to JSF, which I still work with today. I started working with angular too (since 2018, version 6+), in another project, and I had an easy adaptation because JavaScript, which is the basis of the frontend, had been with me since the beginning of my career. This is the life of an IT professional... always learning, always migrating from technology, but always grounded in their roots.

    No, i'm not able to bless your wine (as the other Dionísio, aka, the Greek God of the Wine), believe me, i've tried... What i can bless however, is code! Before entering the world of technologies and programming i was studying to be a Biochemist... so you know i'm used to not know why things work or not and why they don't work. Now that i decided to change my way of life, i am up for your prayers (challenges), just don't try and put me to work with Athena, please and thank you! If you have a problem or are in need of a developer, be it Java, Javascript or the SQLs of life, make your people call my people (aka, me)! -Java with Maven and Spring Boot -HTML and CSS -JavaScript with Node.js and React
