Over the course of my 9-year experience path as a Java Professional, specializing in software components design, database design, testing, and API integration, I have gained hands-on experience in software development with a focus on enterprise, e-commerce, logistics, and entertainment industries.
Using my main tech stack which includes Java, Spring Framework, JUnit, SQL, Docker, Microservices, etc, I have helped clients in these domains grow their digital capabilities by delivering software products that meet their unique needs. As part of distributed teams, I have leveraged my communication skills to provide a delivery-driven approach, ensuring seamless collaboration across different time zones. I have worked closely with team members to identify and resolve issues quickly, leading to successful project outcomes.
Additionally, I have participated in pre-sales and R&D, managed junior developers, and served as a Point of Contact between clients, tech or product management, and team members.
