About

As an experienced software engineer with over seven years in the industry, I have honed my skills across various technologies. I pride myself on being modest, hardworking, and a true team player, valuing responsiveness and communication in problem-solving. My current role as a Senior Full Stack Developer at Ergo Digital IT involves implementing new features, writing unit tests, bug fixing, and creating technical documentation. I also handle release management, stakeholder requirements, project roadmaps, and architecture solutions. Notable achievements include implementing a new logging and monitoring system with Kibana and Elasticsearch, leading the migration from JavaScript to TypeScript, and spearheading the transition to React functional components with hooks. In previous roles, I developed web applications and internal platforms, contributing to projects for insurance brokers, transport companies, and real estate firms. My technological expertise includes Reactjs/Next, Redux/Context API, TypeScript, AEM, GraphQL, AWS, Docker, Node.js, and various databases. My career started as a trainee web developer, where I gained valuable experience that laid the foundation for my current skill set. I hold a Bachelor's degree in Computer Science from Lublin University of Technology and am proficient in both English and Polish. In my spare time, I enjoy working on smart contracts with Solidity and Web 3.

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. “
