What I'm looking for

I’m looking for remote, international project management roles where I can lead multilingual localization, improve QA and workflows with technology, keep delivery on-time within budget, and collaborate with global teams to raise quality.

I’m a results-driven Project Manager and Localization Specialist with 8+ years of experience spanning translation, localization, quality assurance (LQA), and workflow optimization. I specialize in managing multilingual projects, coordinating global teams, and using technology to advance localization strategies.

In my roles, I’ve led quality control for 300+ translation projects, improving translation quality by 25% through feedback and process improvements. I also improved project transparency and efficiency by 40% with tracking systems, while maintaining 100% on-time delivery within budget for 50+ translators.

Beyond management, I bring hands-on language expertise—adapting UX/UI and in-app content, localizing video games, and producing subtitles and closed captions. I’ve translated, localized, edited, and proofread over 500,000 words, and I’m open to remote and international project management roles.
