À propos de Daniel

AI Data Specialist with 5+ years of experience improving Speech AI and Search quality through high-precision human evaluation (RLHF). I curate and refine multilingual (French/English) datasets, run side-by-side model comparisons, and deliver publication-ready transcripts (verbatim or clean-read) for R&D and media use. I’m rigorous about text normalization (numbers, units, abbreviations), dataset consistency at scale, and complex audio scenarios (multi-speaker, overlaps, hesitations, ambient noise).

On top of data work, I also build fast MVPs via AI-assisted prototyping (“vibe coding”) for web & mobile apps—turning ideas into working prototypes quickly, with clear iterations and practical deliverables.

Finally, I bring a strong creative edge: I’m a published poetry author and I create content around philosophy and ideas. That means I care deeply about language, tone, and clarity—useful for UX copy, localization, and overall output quality.

If you need reliable speech/ASR data curation, transcription QA, search relevance labeling, or rapid app prototyping, I can help.
