Hi there, I'm Witold Karaś 👋

Senior Software Engineer | System Architect | Cryptography Researcher

I'm a Senior Software Engineer based in Wrocław, Poland, with a passion for building scalable, secure, and high-performance backend systems. With a strong foundation in the PHP/Symfony ecosystem, my true focus is on solid system architecture, migrating legacy systems to modern microservice-based solutions, and writing clean, maintainable code.

My professional experience is complemented by a deep academic background in computer science. I am currently pursuing a Ph.D. in Applied Cryptography, which provides me with a unique and security-first perspective on software engineering.


🚀 What I'm Currently Focused On

  • Architecting and leading the development of critical backend services for high-traffic e-commerce platforms.
  • Advancing my Ph.D. research in applied cryptography, with a focus on extending the concepts of ring signatures.
  • Mentoring and fostering a culture of technical excellence and best practices within my team.
  • Optimizing CI/CD pipelines to improve development velocity and deployment reliability.
