I am an experienced, agnostic developer with a diverse background in multiple programming languages, including Java, Go, and NodeJS. My primary areas of expertise are in Microservices Architecture, Event and Messaging, and Distributed Systems. I have extensive experience across the complete product development lifecycle, from gathering requirements and analysis to development and deployment. Recently, I have worked as a Team/Tech Lead, where I successfully led and mentored teams to deliver high-quality programs and applications for prominent clients in the Media and Telecom industries. My technical proficiency includes Java, Spring Boot/Cloud, Angular/React, AWS, Kubernetes, and more. During my tenure at Pretius Sp. z o.o., I played a pivotal role in designing and implementing new services and functionalities while collaborating in a team environment to produce top-tier applications. At AND Digital, I led teams working on projects for major banks such as Capital One and Lloyd’s, focusing on microservice development, adopting new deployment tools, and coaching team members. My earlier roles at EY GDS Sp. z o.o. and Asseco Data Systems S.A. involved developing integration solutions, blockchain-based insurance platforms, and billing systems. I possess a strong foundation in both backend and frontend technologies, SQL and NoSQL databases, and DevOps practices, making me a versatile and valuable asset to any development team.Tech Stack
