I’m a Java Backend Engineer focused on building and modernizing production systems—especially where legacy applications need reliable, scalable backend upgrades.

Since June 2025, I’ve worked on an Enterprise FP&A platform for budgeting, forecasting, reporting, and financial data. I’ve contributed to migrating Vaadin 8 modules to Vaadin 24 and implemented new business features, while also integrating backend services with Vaadin-based UI features.

From May 2022 to June 2025, I developed backend features in a microservice architecture for a cloud-based travel management platform used by travel agencies to search, book, and manage flights, hotels, cars, and activities. I integrated external booking and payment providers, implemented REST APIs, supported OAuth2 flows, and worked on NoSQL data migration with CosmosDB—along with fixing production issues and improving existing business logic.

Earlier, at BINARIKS (Jun 2021–May 2022), I delivered backend work on a digital identity verification platform that uses BankID authentication. I built and maintained REST APIs for authentication and verification flows, implemented OAuth2 integrations across providers, and supported deployment to AWS and Azure environments.
