Fullstack Developer at PLANT-MY-TREE
PLANT-MY-TREE®-per-order
The application enables Shopify merchants to automatically place tree-planting orders for every incoming order. By integrating ecological contributions directly into the purchase process, the manual effort for tracking and billing reforestation initiatives is eliminated. The system increases transparency for end customers through real-time visualizations of the ecological impact directly in the storefront. The architecture is based on a modular monolith with Spring Boot in the backend and an integrated React app inside the Shopify admin area. The solution uses webhooks to capture order data in an event-driven way and integrates the weclapp ERP system for automated monthly invoicing. An app proxy mechanism provides dynamic statistics such as CO2 compensation and planted trees without any performance loss for the merchant shop.
Tasks:
- Design of the modular software architecture based on Spring Modulith to ensure high maintainability
- Development of the event-driven business logic for evaluating Shopify orders via webhooks
- Implementation of automated invoicing by connecting the weclapp REST API
- Building the frontend using React Router and Shopify App Bridge for native integration
- Design of the database model and implementation of the persistence layer with JPA/Hibernate and Prisma
- Integration of internationalization processes for global use in the frontend and email communication
- Automation of deployment processes using Docker and GitLab CI/CD
Project skills: Java 25, Spring Boot, Spring Security, Spring Modulith, Hibernate, JPA, REST API, PostgreSQL, Maven, Liquibase, React, TypeScript, React Router, Vite, Node.js, Prisma, Zod, Docker, Docker Compose, GitLab CI/CD, Shopify CLI, Shopify App Bridge, Polaris, weclapp, i18next, Lombok, Vitest

About the technology
What it covers
Internationalization, often called i18n, prepares software for multiple languages and regions without changing the core code for every market. It covers text, dates, numbers, currencies, direction, and layout rules so one product can serve many locales cleanly.
Typical work
- Externalize strings and message catalogs
- Set up locale-aware formatting for dates, numbers, and currencies
- Handle plural rules, gendered text, and fallbacks
- Support right-to-left interfaces and mixed scripts
- Review content flow for multilingual screens
Tools and stacks
Strong specialists work across frontend and backend layers, using resource files, translation keys, locale libraries, and build checks. They often support React, Angular, Vue, Java, .NET, mobile apps, CMS setups, and translation management workflows.
When to bring in help
Companies usually need freelance expertise when a product is going multilingual, when string handling has become hard to maintain, or when releases break localized content. In Dusseldorf, this often matters for teams serving German and international audiences from the same codebase.
What good experts do
Good professionals do more than translate labels. They design clear key structures, keep content separate from logic, test edge cases like truncation and sorting, and make sure locale changes do not break forms, search, or checkout flows.
Signs of maturity
- Clean fallback behavior when a translation is missing
- Locale handling is consistent across screens and services
- Content teams can update text without code changes
- Formatting stays correct in every supported language
- Releases include checks for long text and special characters
Frequently asked questions
Everything clients usually want to know about Internationalization, in one place.
Internationalization prepares a product so it can support multiple languages, regions, and writing systems without rewriting the application for each market. Teams use it for UI text, formatting rules, sorting, plural forms, and right-to-left layouts. It is the foundation that makes localization work later.
i18n is the technical preparation layer: separating text from code, handling locale rules, and making interfaces flexible. Localization adapts the product to a specific language or market, while translation changes the words themselves. A strong freelancer usually understands all three, because they depend on each other.
A strong Internationalization specialist usually also knows localization workflows, content modeling, and QA for multilingual interfaces. They should be comfortable with frontend rendering, backend message handling, and translation file formats. Knowledge of accessibility and UX helps too, because language issues often affect layout and navigation.
Internationalization work needs more than basic translation support when a product has complex UI states, multiple services, or many locales. For a simple website, a focused expert can clean up string handling quickly. For a larger application, you want someone who has handled message catalogs, fallbacks, and release-safe workflows before.
i18n freelancers are a good fit when the team needs short-term depth, a migration, or a clean review before launch. They are also useful when existing code has hard-coded text, inconsistent locale logic, or repeated translation problems. Internal teams often keep ownership after the structure is fixed.
Yes. Internationalization work is usually well suited to remote collaboration because most tasks involve code review, content structure, and test cases rather than physical access. For Dusseldorf teams, remote specialists can work smoothly with product, design, and content owners as long as locale requirements are clear.
Internationalization commonly appears with JSON or properties files, locale libraries, translation management tools, and frontend frameworks that support message keys. In backend systems, specialists often work with message bundles, date and currency formatters, and Unicode-safe text handling. The exact stack depends on the product architecture.
A strong Internationalization expert leaves the product easier to maintain, not just translated. Look for clean key naming, correct plural handling, sensible fallbacks, and tests that catch broken text flow or encoding issues. Good work also keeps product logic separate from content so future markets are easier to add.
