Multilingual Content · SEO · Localisation · Data Analytics
I’m Karla Ruiz de Matos, a multilingual SEO and editorial specialist. For more than ten years, I have researched, written, edited and localised content for international audiences in finance, crypto, iGaming, technology and B2B.
I also analyse business data with SQL, BigQuery, Looker, Power BI and Excel. My experience in search quality and AI data evaluation supports careful research, while web development helps me build and publish digital projects.
View selected projectsThe Work, in Practical Terms
I combine editorial experience, analytical methods and practical web development to research, create and deliver useful work.
I translate search demand into useful content by connecting intent, terminology, competitors and local context with the needs of each audience.
Scalable content depends on clear editorial operations. I create standards, review work, coordinate contributors, resolve inconsistencies and keep the final page aligned with the brief, brand and publishing environment.
I clean, validate and analyse structured data to identify patterns, compare performance and communicate findings. My projects explore credit risk, search demand and service operations, with documented methods and limitations.
I build websites and applications using front-end technologies, CMS platforms and API fundamentals. Practical development helps me connect content, design and functionality, and collaborate with technical teams.

The tools change with the project. I define the question, inspect the evidence, build a useful response and verify the result.
Clarify the audience, business objective, market, constraints and standard of evidence before production begins.
Use search research, source evaluation, data cleaning and competitor context to separate useful evidence from noise.
Write, edit, localise, visualise or implement the answer in a format the intended audience can use.
Review accuracy, language, SEO, accessibility and publishing quality, then measure performance where data is available.
