About

I am an experienced Senior Java Architect and Lead Developer with a strong background in designing, developing, and leading the implementation of complex Java web applications. Over the years, I have taken on significant leadership roles, managing international teams of developers, proposing and implementing technical solutions, and ensuring the successful delivery of high-quality software products. My expertise includes working with Agile methodologies, leading Scrum teams, and setting up source code quality metrics to ensure consistent and reliable output. I have been involved in various high-profile projects, including developing microservices for car manufacturing supervision and banking application systems for identification and verification processes. In my previous roles at companies like Samsung, TomTom, and UniCredit Global Information Services, I was responsible for designing and developing a wide range of applications, from cloud-based services to data processing algorithms involving machine learning. My technical skills extend to cloud technologies, continuous integration, and various Java technologies, allowing me to optimize applications for better performance and scalability. I am also proficient in guiding and mentoring teams, ensuring that best practices are followed, and risks are effectively managed. My education in computer science and numerous certifications in Java and related technologies have further strengthened my ability to deliver robust, high-performance software solutions.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
