Hi there, I'm Kacper! 👋

🚀 .NET Fullstack Developer | Computer Science Student @ CUT

I specialize in building robust C#/.NET backends and I'm currently expanding my E2E stack by actively exploring modern frontend technologies like React and Next.js. From designing relational databases to configuring Docker containers, I enjoy owning the entire development lifecycle. My approach to code is pragmatic: keep it clean, keep it decoupled, and always write tests.

💡 Beyond the Code

  • 🎓 Education: Currently pursuing a B.Sc. in Computer Science at Cracow University of Technology (2023 - 2027).
  • 🤝 The Soft Edge: Thanks to my background in professional customer service, I don't just write code - I solve real problems. I'm used to high-pressure environments and translating complex technical jargon into plain, actionable language.
  • 🤖 AI Workflows: Certified by Google. I actively leverage Prompt Engineering and AI tools to write better code and streamline my daily development processes.
  • 💬 Ask me about: The .NET ecosystem, C# architecture, SQL database design, Entity Framework Core, or containerizing applications with Docker!
  • 📫 Reach me: kacper.gumulak@gmail.com | LinkedIn
  • ⚡ Fun fact: I love solving problems - both in code and while interacting with people. When I'm away from the keyboard, you can find me hitting the gym, exploring new tech trends or practicing my Spanish!
