Senior Full-Stack Developer
Hello, I am the devJeferson Vitor, how are you?
I'm a developer and I turn ideas into digital products, creating interfaces, APIs, web systems, mobile apps, and custom solutions.
$ My journey with programming started when I was 12, learning through videos, online courses and practical projects. I began with JavaScript, creating Discord bots as a way to practice and improve my skills.
$ I have experience with HTML, CSS, JavaScript, React, Node.js, Java, Kotlin, Python, Git, GitHub and REST APIs, building websites, integrations, automations and custom systems.
$ I also worked as an assistant in a computer store from 2019 to 2022, helping with computer and cellphone repair, formatting, system installation, basic technical support and customer service.
$ Currently, I work as a freelance developer, creating websites, mobile applications, APIs, bots and personalized solutions. My main current project is WorthClient, a modified Minecraft client with website, launcher, authentication, APIs and integrations.
