About

As a software developer with a passion for both back-end and front-end development, I approach professional challenges holistically, continually broadening my knowledge in all areas of web development. Currently, I work as a Senior Software Developer at intive, collaborating with a global team on BlackBerry's cybersecurity products. My responsibilities include developing UI using TypeScript, React, GraphQL, Apollo Client, and Material UI framework, as well as extending and maintaining AWS-based services using TypeScript, Node.js, Apollo Server, Elasticsearch, and Docker. I thrive in a SCRUM environment, working across different time zones, closely communicating with other teams, and ensuring the quality of our software through extensive testing with Jest, Cypress, and Pact JS. Previously, I worked as a Full-Stack Web Developer at Codemachine, where I focused on cloud-based projects in the telematics, micro mobility, IoT, and logistics industries. I developed services using Google Kubernetes Engine, App Engine, Cloud Functions, and VMs, and built web apps with webpack, TypeScript, modern React, Redux, redux-saga, and Sass. I optimized CI/CD pipelines, defined technical requirements with clients, and designed critical system components using Google Cloud Platform. I am particularly proud of developing a TCP messages broker that processes millions of packets from client vehicles monthly. My earlier experience includes front-end development and freelance web development, where I honed my skills in various technologies and contributed to diverse projects. I hold a Bachelor's degree in Economic Analytics from Wrocław University of Economics, and I am an AWS Certified Solutions Architect.

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. “
