About

As a seasoned developer, my experience spans various roles primarily focused on Java and Kotlin microservices development. Most recently, I worked at Scalo/Bitpanda, where I was involved in developing a platform for trading cryptocurrencies and commodities. Prior to that, I contributed to a comprehensive banking system at Connectis/Vodeno, implementing microservices architecture with an event-driven approach using Apache Kafka. My roles often included designing system architecture, managing deployments with Docker, and ensuring smooth CI/CD pipelines. At Connectis/Circle K, I developed a mobile application for electric vehicle charging, emphasizing synchronization with charging vendors and managing complex backend functionalities. My technical expertise covers a wide range of tools and technologies, including Java 8, Spring Framework, Docker, and various cloud platforms like AWS and Google Cloud. I have a solid foundation in Agile methodologies, particularly Scrum and TDD, which I utilized across different projects to ensure efficient and reliable software delivery. My educational background in business applications programming from the Polish-Japanese Academy of Information Technology has provided a strong base for my career. Beyond my professional pursuits, I enjoy making homemade pizza and beer, and I am committed to maintaining an active lifestyle.
