Description

Hello! I'm Marvin.

For over 6 years, I've been developing complex web applications for medium-sized and large companies. My focus is on modern Vue 3 frontends combined with robust Java/Kotlin backends in a microservice environment.

What I work with daily:

Frontend: Vue.js (v2/v3), Nuxt.js, TypeScript, Pinia, State Management

Backend: Java (v8-v17), Kotlin, Spring Boot, REST APIs, GraphQL

E-Commerce / CMS: Storyblok, Bloomreach, Commercetools, Keycloak (OAuth 2.0)

DevOps: Docker, Kubernetes, CI/CD Pipelines, Zero-Downtime Deployments

Testing & Quality: Playwright, Cypress, Code Reviews, Mentoring

Project Experience including:

Frontend migrations from Vue 2 to Vue 3 (leading German care sector shop)

Headless e-commerce with Storyblok/Commercetools (B2B & D2C)

Java backend modernizations (Java 8 to 17 migrations)

Integration of AI APIs (OpenAI) including GraphQL layer

Bloomreach CMS integrations for large clients

What sets me apart: I think architecturally and deliver code that remains maintainable even in two years. Instead of "quick and dirty," I deliver clean solutions that grow with the project. I communicate clearly, meet deadlines, and give early notice if something needs to be done differently.

Available for: Medium-term projects (weeks to months), Vue/Java migrations, e-commerce setups, code reviews, and architecture consulting. Short-term specialist assignments are also possible.
