Software Engineer

I am a proficient full-stack Java and Python programmer, primarily focusing on front-end and back-end development using Java and Python. I've worked on a range of projects during my long career as a freelancer, demonstrating my expertise with front-end technologies like HTML, CSS, JavaScript, React, or Angular, as well as frameworks like Spring Boot, Quarkus, Fast API, Django, and Flask. I've developed sophisticated mobile applications and interactive websites while working with many clients. I have experience integrating databases, including Oracle, PostgreSQL, and MySQL, and I know a lot about server technologies, especially AWS and Google Cloud Platform (GCP). Using test-driven development (TDD), continuous integration/deployment (CI/CD), and object-oriented programming, I follow best practices in my development methodology. I thrive at converting customer requirements into practical, workable solutions. I am well-known for my ability to work autonomously, my meticulous attention to detail, and my commitment to meeting deadlines. My technical proficiency and adaptability make me a priceless asset for projects requiring skilled and agile web and mobile development.
