Nothing is impossible, it all depends on how much time you have to spend on it
<About me/>
Hi, I am a Full-Stack Developer, software architect and co-founder of Catbyte who designs and builds complete web applications and systems. I turn product requirements into scalable, maintainable solutions, from system architecture and data models to polished user interfaces.
My core stack includes React, Next.js, NestJS and SQL databases. I enjoy working across the entire development lifecycle: defining the architecture, designing APIs, modelling data, implementing business logic and delivering reliable frontend experiences.
I approach every project with a focus on scalability, performance, security and thoughtful user experience. Independence, persistence and patience help me solve complex problems and create systems that are built to last.
Here you can find technologies and skills I am using to work with:
