Who am I
Hi, I'm Joao, a 22-year-old software developer with a passion for coding. With 5 years of experience in the field, I have gained extensive knowledge and skills. As a Medium-level Software Developer, I specialize in back-end development. I excel in creating Rest API, graphQL API, and Microservices with a focus on quality and clean code. My primary programming languages are Java and Typescript, and I am proficient in frameworks such as Spring Boot and NestJS. In addition, I have expertise in databases, infrastructure, and testing. I have hands-on experience with databases like Postgres, MySQL, MongoDB, and Oracle. I am familiar with tools such as Docker, Jenkins, Keycloak, as well as testing frameworks like Jest and JUnit. When it comes to front-end development, I am well-versed in ReactJS and NextJS. I have experience working with state management libraries like Redux, MobX, and Zustand.
Beyond my technical skills, I am a fast learner and actively cultivate study habits. I have honed my English skills to almost fluent through self-directed learning online. I am constantly seeking new knowledge and refuse to give up until I can apply new skills effectively in projects or other endeavors. Feel free to check out my YouTube channel, "joaoptgaino", where I share tech-related videos and insights. I am eager to bring my expertise, dedication, and passion for coding to contribute to exciting projects and deliver outstanding results.
