tchojnacki/README.md

I am a mid full-stack software engineer specializing in React and NestJS, with strong foundations in databases, DevOps, AI, Python, and Rust. Currently, I work on EPM and CPaaS solutions for a telecommunications company, supporting 2 000+ networks and over 100 000+ VoIP customer lines. My role combines scalable system design with real-world reliability requirements in high-availability environments.

Previously, I interned at Atlassian, where I delivered production features to Jira, contributing to a product used by 300 000+ teams worldwide. As a freelance developer, I partnered directly with clients to design, build, and deploy high-performing websites attracting 2 000+ monthly users, translating business needs into practical technical solutions.

I hold both a Bachelor's and Master's degree in Applied Computer Science from the Wrocław University of Science and Technology, graduating top of my class. I also published scientific research in Information and Software Technology, a top 10% journal according to CORE rankings.
