Continuous translations for agile software development
Agile sprints mean content updates are rolled out every few days or weeks. Such tight translation timelines require maximum efficiency in the processing and file handling steps, and a stringent workflow for project managers and translators to stay on track.
We develop and automate localization workflows to oversee time-critical release schedules, ensuring unforeseen delays do not cascade further and impact your entire release schedule.
Automate and streamline localization processes
Our clients save time and money with LanguageDesk, our free translation project management tool that streamlines tedious manual steps involved in file handling and project communication.
Furthermore, our localization engineers increase productivity with custom-developed scripts for file processing (based on your existing tech setup) saving you time and effort in exporting and importing translated content.

In-context translation for maximum ease of use
Context is vital for translators to deliver accurate software and app localizations. Missing visual context can lead to misaligned user interfaces and design breaks, preventing users from operating your software intuitively in their native language.
Our translation tools empower translators to produce their best work by giving them maximum information on how each respective GUI (graphic user interface) string fits into your user interface.
For optimum quality, we can also streamline query management to gather questions from translators in one place, so everyone is always on the same page.
We work with all common software localization formats
- .xml
- .xliff
- .json
- .resx
- .properties
- .strings
- .yaml
- .po
- .md/.markdown
How we translate your technical documents
Every project follows a structured, customizable workflow designed to integrate with your agile development cycle, so that localized builds ship on time, every time.
File analysis & project scoping
We extract and analyze all translatable strings from your resource files: .resx, .json, .po, .xml, and more. Our engineers identify placeholders, variables, and dependencies to ensure proper functionality. Part of the analysis also includes assessing the most suitable product for the content type, client needs, and project characteristics, while evaluating volume, complexity, and timeline to scope the project accurately.
Glossary, termbase & style guide development
Consistent terminology is non-negotiable in software localization. We build client-approved termbases covering product features, technical terms, and UI conventions for every target language. Combined with brand-specific style guides, these resources define formatting rules for dates, currencies, units, and tone of voice, ensuring every translator is aligned from day one.
Translation & contextual review
We work exclusively with native-speaking linguists who have proven expertise in software localization. To support accurate translations, we provide essential context through screenshots, reference builds, and developer notes. Whenever possible, linguists can also work directly within the user interface, allowing them to view strings in context and ensure greater precision and consistency across the product.
Linguistic & functional QA
Every translation passes through a multi-layered QA process. Our linguistic reviewers check for grammar, terminology accuracy, and cultural appropriateness. Automated QA tools flag placeholder mismatches, formatting errors, and truncation risks. For critical releases, we perform functional testing in target environments to verify that localized content displays correctly, supports right-to-left scripts, and handles text expansion without breaking layouts.
Continuous localization & updates
Software doesn't stop evolving - and neither do your translations. Through integrations with GitHub, GitLab, Bitbucket, and your CI/CD pipeline via the LanguageDesk API, new strings are automatically detected, translated, and deployed with each sprint. Your translation memory and termbases grow smarter over time, making every subsequent release faster, cheaper, and more consistent than the last.
Advanced technologies we use for software localization
We're technology-agnostic, which means we choose the best tools for your stack, not ours. Here's the technology layer that powers every software localization project at Milengo.
Translation memory (TM)
Cloud-based TM stores every approved translation for reuse across releases and product lines. Identical and similar strings are recalled automatically, cutting turnaround time and costs while ensuring consistency across your entire software portfolio.
Termbase management
Client-specific termbases define approved translations for product names, features, UI labels, and technical vocabulary. Managed centrally through LanguageDesk, termbases ensure brand consistency across all languages, products, and teams — with version control and audit trails.
AI & machine translation engines
We integrate with DeepL, Google Translate, Microsoft Translator, and custom-trained LLMs, selecting the optimal engine for your language pair and content type. Combined with subject-matter expert post-editing, our AI-enhanced workflows deliver up to 70% cost savings on high-volume software content.
Continuous localization APIs
The LanguageDesk API connects directly to your repositories and build systems. New strings are detected and queued for translation automatically as they're committed, while keeping localization in sync with your agile sprints without manual file handoffs or project kickoffs.
Automated QA checks
Our platform runs automated linguistic and technical quality checks before delivery, flagging missing translations, placeholder mismatches, formatting inconsistencies, and character encoding issues. This catches defects before deployment, reducing costly post-release hotfixes.
Human native-speaking industry experts
We work with native-speaking linguists and experienced vendors who specialize in software localization. Our translators are subject-matter experts with strong knowledge of their local markets, ensuring accurate terminology, cultural relevance, and natural user experiences.
Quality guaranteed
Quality assurance & testing
At Milengo, quality isn't a final checkbox - it's embedded in every stage of the localization workflow. We combine automated tooling with human expertise to ensure your localized software is linguistically accurate, functionally sound, and culturally appropriate for every target market. LQA dashboards track the quality of every proejct.
Our ISO-certified process means every translation is checked by a second qualified linguist before delivery. For machine-translated content, professional post-editors refine the output to ensure fluency, correct terminology, and alignment with your brand voice, following ISO17100 standards for human quality assurance in translation.
Beyond linguistic quality, our localization engineers validate that translated builds behave correctly in target environments, handling complex file formats, catching truncation, encoding errors, placeholder mismatches, and layout breaks before they reach your users.
