Summary
As an accomplished software developer with over 11 years of experience, I have a diverse range of skills and knowledge that make me an invaluable asset to any company. I began my career working with desktop systems for 7 years, gaining a strong foundation in software development principles and techniques. I then transitioned to web development, where I have spent the last 4 years working primarily with Java and the Spring boot framework.
In addition to Java, I am proficient in Node.js and have experience working with ReactJS, making me a versatile full-stack developer. My expertise extends to a range of databases, including Oracle, PostgreSQL, MySQL, and MongoDB. I am also highly proficient in working with Docker, AWS, and RabbitMQ, enabling me to build and deploy highly scalable and reliable applications.
Throughout my career, I have worked in a variety of market sectors, including commerce, industry, justice, analytical security, and auction. I have consistently demonstrated my ability to work collaboratively with cross-functional teams to deliver projects that meet or exceed expectations.
In addition to my extensive hands-on experience, I am committed to continuous learning and improvement. Currently, I am studying more deeply about software architecture and other theoretical foundations to further enhance my skills and knowledge. My goal is to become a technical reference within my field and to leverage my expertise to drive innovation and excellence within the organizations I work with.
