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

REST
