FERNANDO PIRES

I help software, SaaS, AI, and fintech companies localize their products for the Brazilian market.

Unlike traditional translation services, I work directly with software localization workflows, combining Brazilian Portuguese localization with technical implementation and quality assurance.

My services include:

• English → Brazilian Portuguese (pt-BR) software localization
• UI, menus, messages, settings, and user-facing content
• JSON and i18n localization files
• Localization implementation and integration
• Git/GitHub workflows, branches, commits, and pull requests
• Localization QA and consistency checks
• Key and interpolation-variable validation
• Testing and build validation
• Identification of untranslated, hardcoded, or inconsistent strings
• Brazilian terminology and cultural adaptation
• Technical documentation localization
• AI and LLM product localization and evaluation

I can work directly with an existing repository and deliver a tested pull request instead of simply returning translated text.

Portfolio example:

I implemented the Brazilian Portuguese localization for HKUDS/Vibe-Trading, an open-source AI-powered quantitative research and trading platform. The contribution localized 1,482 UI strings, integrated pt-BR into the application's i18n architecture, preserved key and interpolation-variable parity, updated automated tests, passed the complete frontend test suite (607 tests), passed the production build, and was reviewed and merged into the official project.
