What I'm looking for

I’m looking for a role where I can build and own end-to-end payment platforms and integrations, partner on technical decisions, and deliver with Java/Spring Boot, React, and modern cloud tooling in a strong engineering team.

I’m a Senior Full Stack Developer focused on the payment sector, currently building end-to-end payment integrations and payment backoffice capabilities. I also support internal payment-related projects across a number of initiatives within Kindredgroup.

My work is hands-on and ownership-driven: I develop, participate in making decisions about development, and own components across the stack. I primarily work with Spring Boot (Java) and React (JS), and I bring additional backend strength with Hibernate and related Java technologies.

Previously, I built a connector framework and connectors and handled integration with the SmartTrack platform for cloud and SaaS use cases. I worked with Kotlin/Java, Corutines, REST APIs and SOAP implementations, and cloud services like AWS and Google cloud.

Earlier, I developed products such as a PayData platform (Angular 8 frontend), a webshop with categories/cross-sales and payment features (Spring Boot and React), and a BioSave pregnancy monitoring app (React Native). I’m also always eager to explore and learn more.
