Summary
I have been working for about 15 years in software specification and development, as a technical project manager, lead developer and system architect in agile teams. My project portfolio covers banking, government agencies, wholesale, healthcare, automotive and telecommunications. Part of my role is to analyze business requirements, help create requirement documents (e.g. user stories), design the related data model and interface architecture, and implement according to current IT standards in agile methodologies.
In doing so, I design or extend microservices cloud architectures and full-stack applications in modern IT systems using JEE, Spring Boot and Micronaut frameworks, with SQL or NoSQL databases, REST interfaces or asynchronous event-driven models based on message queues like ActiveMQ, Kafka or RabbitMQ.
I usually work with in-house or nearshore teams of about 5–10 people, including specialized front-end and back-end developers, where I often take on a coordinating and steering role, create detailed specifications, and carry out progress tracking and code reviews according to agreed acceptance criteria. My main development focus in Java and Kotlin is the back end, but I also develop on the front end (especially React).
I also have a strong background in test automation and test-driven development, as well as setting up CI/CD pipelines using Jenkins and GitLab/Bitbucket with Docker and Ansible.
I am communicative, learn new fields quickly and have an autonomous and methodical approach. I am also used to working out and agreeing on constructive solutions with all stakeholders in complex or conflict-prone situations.
