Hi there, I'm Kacper Gumulak! 👋

🚀 .NET Fullstack Developer | Computer Science Student @ CUT

I bridge the gap between robust backend architectures and modern web interfaces, taking applications through their full lifecycle—from initial database design to fully containerized deployments. I am deeply passionate about Object-Oriented Programming, clean architecture patterns (like MVC and MVVM), and building scalable E2E solutions. My core development philosophy is simple: "Clean code is tested code."

💡 Beyond the Code

  • 🎓 Education: Studying Computer Science at Cracow University of Technology (2023 - 2027), building a strong foundation in software engineering, algorithms, and relational database systems.
  • 🤝 Soft Skills Advantage: With a solid background in professional customer service, I bring more than just code to the table. I excel at working under time pressure, rapid troubleshooting, and translating complex technical jargon into accessible, user-friendly language.
  • 💬 Ask me about: The .NET ecosystem, REST APIs, Entity Framework Core, SQL databases, Docker, or the unique challenges of building a platform entirely without frameworks!
  • 📫 Reach me: kacper.gumulak@gmail.com | LinkedIn
  • ⚡ Fun fact: When I'm not debugging C# or configuring Docker containers, you can usually find me hitting the gym, exploring new tech trends, or practicing my Spanish!
