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 localization library for multilingual web apps. It handles translation keys, language detection, interpolation, plural rules, and fallback languages. Teams use it to keep product text consistent across UI, content, and regional releases.
Common setups
- React apps with react-i18next
- Next.js projects with SSR or hydration
- Translation loading from JSON, API, or CMS sources
- Language switchers, routing, and namespace design
Strong specialists keep keys stable, structure translation files clearly, and make sure copy changes do not break the interface.
Why companies bring help
Companies usually need freelance expertise when localization has grown messy or release work is blocked by copy changes. A specialist can fix fallback chains, remove duplicate keys, and align i18next with product, content, and engineering workflows.
In Germany, this often matters for SaaS teams, e-commerce stores, and internal tools that serve users in more than one language. Remote work is common, but on-site sessions help when the team needs to review terminology, UX copy, or content ownership.
Ecosystem skills
Good i18next professionals usually know more than one framework path and can move between frontend and content tooling. Useful adjacent skills include:
- React, Next.js, or Node.js
- JSON file structures and translation pipelines
- ICU-style message handling and plural logic
- Testing for missing keys and broken language fallbacks
What strong specialists deliver
A strong specialist can turn a fragile translation setup into a maintainable system. That includes clean namespace boundaries, predictable key naming, safe fallback behavior, and a setup that supports growth without endless manual fixes.
They also think about translators and editors, not only code. Good work makes translations easier to review, easier to ship, and less likely to drift between languages.
When to hire
Bring in help when your app needs a new language, a framework migration, or a cleanup after years of ad hoc translation work. You also want support when language files are too large, copy is duplicated across features, or developers keep shipping missing-text bugs.
The best freelance experts document the setup, explain trade-offs clearly, and leave the team with a system they can keep using.
Frequently asked questions
Key details about i18next, drawn from the questions we get asked most.
i18next is used to manage translations in web apps and JavaScript products. It helps teams switch languages, load translation resources, handle plural forms, and keep UI text separate from application logic. That makes it useful for customer portals, SaaS products, and content-heavy interfaces.
i18next is usually chosen for flexible key-based translation workflows and broad framework support. react-intl and FormatJS lean more toward message formatting patterns, while i18next often fits teams that want a simple core with plugins and framework bindings. The right choice depends on your app structure and how much control you want over translation files.
A strong i18next specialist usually knows the frontend framework around it, especially React or Next.js. They should also understand translation file structure, fallback logic, interpolation, and testing for missing keys. If your product uses CMS content or localization pipelines, that experience helps too.
For a small cleanup, a specialist with solid practical experience can be enough. For a larger rollout, you want someone who has handled namespaces, language detection, and app-wide translation architecture before. The key is not just using i18next, but keeping it maintainable over time.
Yes, i18next work is often a good fit for remote collaboration. Translation logic, file structure, and frontend integration can be reviewed asynchronously, which suits distributed teams well. If terminology is sensitive, a short workshop with product or content owners can still help align the language.
Ask whether the i18next specialist has shipped production work with your stack and can explain how they handle fallback languages, namespaces, and translation loading. Review examples of clean translation structure, not just screenshots. You want someone who can make the setup easier for both engineers and content editors.
No, i18next is not limited to React. It works with many JavaScript setups and is often used with Node.js, Next.js, and other frontend stacks through integrations and plugins. React is common, but it is only one part of the ecosystem.
If translations are hardcoded, keys are duplicated, or missing text appears during releases, your i18next setup likely needs attention. Another sign is when adding a new language slows down every feature team. That usually means the structure needs cleanup before the product grows further.
