Senior Software Engineer

Paweł Król

I build web applications from the interface to the API: React, TypeScript, Node.js and AWS. Based in Warsaw.

I have been working as a frontend developer since 2020 and, since August 2026, as a Senior Frontend Developer at Wirtualna Polska. At Nike, I built large internal applications used by teams across many markets.

Before moving into software, I spent twelve years in banking, purchasing and sales. That experience taught me how the people who use an application actually work, so it is easier for me to understand what they need.

I run projects end to end: I plan the architecture, write the code, deploy it and keep it running in production. I take ownership of technical decisions and make sure the code is readable, secure and easy to maintain.

I specialise in React and TypeScript, but my work is not limited to the frontend: I also build backends in Node.js and work with AWS and GraphQL. I have spent many years working in international teams. I speak fluent English.
