Nice to meet you, I’m Tomislav Pree
I’m a full-stack developer and tech consultant passionate about building efficient, secure, and visually appealing web applications. Since 2018, I’ve completed successful projects across backend and frontend, always focused on performance, user experience, and scalability.
The first Mobile App in 2018
It all started in 2018 with my first real project: a collaboration app for construction workers. I was thrown into the cold water, working with a team for the first time on a real-world product. It was challenging, chaotic—and exactly what I needed. That experience lit a spark in me. Since then, I’ve been hooked on transforming abstract ideas into products people can actually use. I love the entire process: shaping concepts, solving tough problems, and bringing something new into the world.
How I started as a developer
I discovered my passion for building digital products while studying computer science. What began as curiosity quickly turned into late nights debugging, designing, and deploying—just for the thrill of seeing something come to life.
Over 8 years of experience and 20+ projects
