Etienne Billong
@etiennebillong
I evaluate English-French AI translations and protect data integrity through precise scoring and error analysis.
CameroonWhat I'm looking for
I evaluate English-French AI translation outputs, identify semantic and localization errors, and provide granular quality scores that improve linguistic datasets.
At LUEL Platform and through freelance projects, I conduct LLM preference ratings, RLHF-based evaluations, source-target audits, and annotation compliance testing for international localization and engineering teams. I structure complex translated content, flag tone mismatches and technical issues, and deliver native-French linguistic alignment under rapid production cycles.
At Crédit Foncier du Cameroun, I lead loan-analysis workflows and use rigorous assessment frameworks to review complex portfolios and technical risk reports. I designed Excel-based diagnostic tools that isolated a billing anomaly exceeding 10,000,000 FCFA while maintaining bilingual semantic consistency across English and French reporting.
My background in civil engineering, data auditing, Excel verification, and bilingual reporting helps me bring disciplined analysis to high-precision AI training and data-quality work.
