Javier Omar C.

Spanish Translator Expert | Expert AI Proofreader, LQA & Subtitler

14+ years of delivering linguistic precision for global industry leaders. As a member of the National Association of Graduates in Translation and Interpreting (CONALTI, Venezuela) (member association of the International Federation of Translators (FIT/IFT)), I bridge the communication gap between complex technical sectors and the Spanish-speaking world. My approach combines a deep architectural background with cutting-edge AI-integrated workflows to deliver translations that are not only accurate but culturally and strategically impactful. Why partner with me? I don’t just translate words; I localize experiences and secure compliance. My expertise is built on three high-stakes pillars: EdTech & Gamification: During my tenure at Duolingo and Amino Apps, I localized entire app ecosystems and curricula for millions of users, specializing in Linguistic Quality Assurance (LQA), gender-agreement audits, and cross-dialectal adaptation (Spanish MX, AR, ES, CO, VE). Fintech, Crypto & Web3: At Deriv and through Contentoo, I specialized in high-complexity trading platforms, blockchain terminology, and AML/Compliance content, achieving a consistent 100% quality score. Legal, Healthcare & Public Sector: Long-term collaborator for The Spanish Group and Baystate Interpreters, managing sensitive vital records (USCIS/Embassy standards), IEPs, and social housing documentation with strict confidentiality (HIPAA/FERPA-compliant). Technical Mastery: I leverage a robust CAT Tool stack (MemoQ, Phrase, SmartCat, Crowdin, Transifex) and Generative AI (Prompt Engineering) to optimize turnaround times while maintaining the highest stylistic integrity. Core Specialized Areas: Engineering & AEC: 11-year tenure as the lead translator for the Advanced Building Skins International Conference. iGaming & Marketing: SEO-driven localization and transcreation for B2B and B2C global campaigns. Digital Excellence: Expert-level LQA, functional bug reporting, and subtitle synchronization. Let's connect if you are looking for a proactive, tech-savvy linguist who understands that in localization, precision is the ultimate ROI.
