Mobile design
- Intended for mobile devices, but works on other platforms too, including support for keyboard-only use.
Progressive Web App
- Users are able to install it like an app and use it offline, with the project structured to work directly in the browser without requiring additional software.
Full privacy
- Structured so the server provides only the website code, with all actions and data kept on the user’s device.

The Story So Far
My journey in web development spans over a decade, evolving from front-end internship to full-stack expertise through continuous learning and hands-on experience.
React has become my tool of choice after years of exploring various approaches. I appreciate its balance of flexibility and structure, which makes it practical for building reliable, maintainable projects at any scale.
I've had the privilege of helping build a CRM platform from the ground up, watching it evolve into a modern microservices architecture serving businesses across Europe. This journey taught me how systems grow and adapt over time.
When not immersed in code, I enjoy exploring new technologies, sharing knowledge, and finding inspiration in everyday moments—often with a cup of coffee in hand.
Philosophy
In a dynamic environment like JavaScript, there's no such thing as perfect code; what's optimal today might change tomorrow.
That's why I believe the foundation of good code is modularity and clear separation of concerns. This approach not only makes projects easier to maintain and adapt, but also ensures that solutions remain robust as the landscape evolves.
My experience has taught me that the most successful applications are user-driven. No matter how technically elegant a solution is, the end user will always have something to say about it—as they should. That's why I believe in including users throughout the development process whenever possible, balancing technical considerations with real-world feedback.
