Last position:
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 i18next does
i18next is a JavaScript internationalization library for web apps and product interfaces. It helps teams manage translations, language detection, plural rules, and fallback content without hard-coding copy into the app.
Where it fits
It is common in React, Next.js, Vue, and Node.js stacks, but it is not limited to one framework. Teams use it for customer portals, SaaS products, checkout flows, help centers, and any product that must support more than one language.
Typical work
- Set up translation keys and namespaces
- Connect language detection and routing
- Configure fallback languages and missing-key handling
- Integrate with JSON, HTTP backends, or CMS content
- Localize dates, numbers, and plurals
Related tooling
i18next often appears with react-i18next, next-i18next, i18next-browser-languagedetector, and backend loaders. Strong specialists also understand ICU-style messages, content structure, and how to keep translation files maintainable as products grow.
When freelancers help
Companies bring in freelance expertise when a release needs multilingual support fast, when an existing setup is messy, or when product teams want better translation workflows. In Germany, this often matters for B2B software, e-commerce, and regulated products that need clear German and English content.
What strong specialists deliver
A good i18next professional keeps the app clean, the copy consistent, and the language behavior predictable. They reduce hard-coded text, avoid broken fallbacks, and leave a setup that content teams and engineers can maintain without friction.
Frequently asked questions
Key details about i18next, drawn from the questions we get asked most.
i18next is used to add multilingual support to apps and websites without scattering translation logic through the codebase. It handles language selection, translation lookup, pluralization, and fallback behavior so product text stays organized.
i18next is usually chosen when teams want a flexible translation system that works across frameworks and can grow with custom loading, namespaces, and backend sources. react-intl and FormatJS can be a better fit when a team prefers message formatting centered on React or a stricter ICU-style approach.
A strong i18next specialist usually understands the front-end framework in use, common translation file formats, and locale-aware formatting for dates, numbers, and plurals. For larger products, knowledge of Next.js, Node.js, CMS integrations, and content workflows is also valuable.
A small i18next setup may only need someone who can wire translation files, language detection, and a few UI routes. Larger products need deeper experience with namespaces, lazy loading, SEO-safe localization, and coordination with content teams.
Yes, i18next is widely used in both React and Next.js projects, often through react-i18next or next-i18next. The main difference is how routing, server rendering, and language files are handled, so the specialist should know the framework details.
Ask how the i18next specialist handles German and English content, translation handoff, and locale-specific routing. If your product serves users in Germany, also check that they can work cleanly with your existing design, content, and release process.
A solid i18next setup keeps keys readable, avoids duplicated copy, and loads the right language with reliable fallback rules. It should also support content updates without forcing code changes for every text edit.
Most i18next work can be done remotely because it mainly involves code, translation structure, and review of content behavior. On-site work helps when product, design, and content teams need tight workshops, especially for launch planning or complex localization decisions.
