Your app needs more than translated text to support multiple languages. It needs a reliable localization system connecting the codebase, translation platform, development team, and release workflow.

I will integrate a translation management system such as Phrase, Localazy, Tolgee, Lokalise, Crowdin, or Weblate into your web or mobile application. This is a localization engineering service, not a translation service.

Interface text is hard-coded throughout your application

Developers manually send JSON, PO, YAML, or spreadsheet files to translators

New or updated translations regularly miss product releases

Translation keys are duplicated, inconsistent, or difficult to maintain

Your team purchased a TMS but needs help connecting it to the application

Language switching, fallback locales, pluralization, or formatting is unreliable

You want localization updates synchronized through Git, API, CLI, or CI/CD

You need to migrate from an existing localization workflow

Depending on your application and selected platform, the project may include:

Codebase and localization-readiness review

TMS project configuration

Framework SDK or i18n library integration

Extraction of hard-coded user-interface strings

Translation-key structure and naming conventions

Locale-file configuration and synchronization

Language detection and language-switching behaviour

Fallback-language configuration

Pluralization and variable interpolation

Locale-aware dates, numbers and currencies

GitHub or GitLab repository integration

Translation push-and-pull automation

CLI, API, webhook, or CI/CD configuration

Missing-key and fallback testing

Basic right-to-left readiness checks

Developer and translator workflow documentation

Technical handover

I work with React, Next.js, Vue, Nuxt, Angular, JavaScript and TypeScript applications, as well as common localization formats including JSON, YAML, PO, XLIFF, ARB, iOS Strings and Android XML.

You will receive:

A working localization integration in your application

A configured TMS project and synchronization workflow

Tested language loading, switching and fallback behaviour

Organized translation keys and locale files

Setup and maintenance documentation

A handover explaining how your team can add languages and update strings

Translation and linguistic review are not included. You can provide existing translations, work with your preferred translators, or manage translations directly through the selected platform.

Because codebases and localization requirements vary, I review the application, framework, number of strings, existing i18n setup, target platform and automation requirements before confirming the scope.
