Level 1
About this gig
Looking for a custom Vaadin application or professional help with an existing Vaadin project? You are in the right place.
I specialize in developing modern Java-based web applications using the Vaadin framework. My focus is on clean architecture, performance, and maintainable code. Whether you need a new Vaadin application, feature extensions, bug fixes, or optimization, I can deliver production-ready solutions tailored to your needs.
My strong suits are:
Java (Vaadin, Spring Boot, full-stack web application development)
Vaadin Flow & Hilla (UI development, custom components, theming, routing, forms, grids)
Backend integration (REST APIs, business logic, authentication, security)
SQL (database design, integration, optimization)
Maven & Gradle (build automation and dependency management)
Other technologies are possible as well, but Vaadin-focused projects are where I work most efficiently.
What I can help you with:
Custom Vaadin application development
Bug fixing and troubleshooting in Vaadin projects
UI/UX improvements and theming
Performance optimization (frontend and backend)
Code review, refactoring, and modernization
Vaadin version upgrades and migrations
