Osvaldo Kalvaitir
Hello! My name is Osvaldo, and I have over 18 years of experience in software development. I currently work as a Senior Full Stack Software Engineer focused on mobile at Next Ip, located in São Paulo/SP. For many years, I'm focused on the JavaScript stack with TypeScript: Node.JS, ReactJS and React Native. Passionate about technology since I was a child, I like all the stages of creating and managing a project, such as: requirements gathering and analysis, UI/UX prototyping, development, testing, implantation and maintenance.
Currently, I am enhancing my professional skills by completing courses. Subsequently, I plan to direct my focus towards deepening my knowledge in Python and Artificial Intelligence (AI). I am enthusiastic about exploring this new realm and applying the acquired knowledge to projects involving these innovative technologies. I believe that the combination of my experience with the versatility of Python and the exciting field of AI will bring new perspectives to my professional journey, propelling my growth and contribution to the team.

Interests
I am fascinated by many arts, I like to program listening to music, I am eclectic, but to program I like the songs that make me travel in the codes. I always take programming courses to keep myself updated and apply my knowledge at work using the newest technologies.
If you weren't a programmer, you would be a UI / UX designer. It pleases my eyes when I see a really beautiful interface with all its color schemes and combinations, animations and apps that care about the user experience.
I keep myself informed daily by reading news and articles about technology, culture, politics and about the world. I exercise by going to the gym to keep my body and mind healthy.
On weekends, when I'm not studying, I like camping at the dam or venturing into the kitchen, learning a new recipe, by the way, since I love cooking and I learned very well =). I love going out with friends to catch up or catch a movie / series with my family at home to relax.
I like games, especially strategy. I love perfumes, those that transport us to another dimension. I love collections of anything.
I haven’t been traveling because of the daily rush, but I intend to travel at least once a year to reinvigorate my energies!
