Jakub Havlíček

Full Stack Engineer

I deliver end-to-end solutions - reliable, maintainable, and always user-first.

I’m a full-stack developer with a strong background in backend development and a growing love for modern frontend frameworks like Svelte and React. I’ve spent years building scalable, efficient systems using Java, Python, and Go, and I’m just as comfortable creating seamless, dynamic user experiences on the frontend. I take pride in crafting software that doesn’t just work but feels right to use.

Over the course of my career, I’ve gained extensive experience with the tools and processes that drive modern development. From building CI/CD pipelines to managing cloud infrastructure with AWS and containerization with Docker, I know how to streamline workflows and bring ideas to life. Whether it’s a small project or a complex application, I focus on delivering solutions that are robust, maintainable, and future-ready.

I thrive on challenges and enjoy creating end-to-end applications that bring together clean code and thoughtful design. My goal is to build software that’s not only technically sound but also a delight for users. Every project is an opportunity to push boundaries, learn something new, and solve problems creatively.

When I’m not coding, I’m probably exploring new frameworks, tinkering with tools, or just brainstorming new ideas. I’m passionate about what I do and always looking for ways to improve, grow, and build something amazing.
