About

As a dedicated professional with 15 years of experience, I have honed a strong client-centric approach and a commitment to delivering exceptional results. My expertise lies in Java backend development and full-stack development, with proficiency in both spoken and written English. My recent role as a Senior Java Backend Engineer at Vodafone UK involved fixing performance and multi-threading issues, implementing Contract-Based Testing, working with complex OpenAPI models, and mentoring team members. Additionally, I supported production issues using DataDog and worked with Azure DevOps to implement on-demand deployment. Previously, I served as the Main Java Backend Engineer/Full-Stack Developer at Firstdata in Warsaw, where I created REST APIs, led the introduction of Kotlin, developed microservices for integrations and ETLs, and improved platform performance. My background also includes significant roles at HuuugeGames, Ziflow, SkyCash, and Żagiel, where I developed a variety of applications, optimized performance, and led successful migrations to AWS. With a solid academic foundation from the Warsaw School of Computer Science and excellent flexibility, communication skills, and a phenomenal ability to learn, I am well-equipped to contribute effectively to any team.
