Antonio Herrera

I’m a Systems Engineer and bilingual Spanish-English professional who applies both technical rigor and native language fluency to AI evaluation. I focus on making AI outputs accurate, clear, useful, and culturally natural for real users.

In my current freelance work, I create and refine product and social content using AI-assisted workflows, then review it for realism, brand consistency, and commercial quality. I also develop prompts, captions, product concepts, and content directions for platforms like TikTok and e-commerce channels.

Earlier, I served as an SAP Business Intelligence Consultant / Systems Engineer, working with SAP BW, SAP BO, SAP HANA, SQL/SQLScript, and business intelligence reporting. I analyzed requirements, validated data outputs, reviewed reports, documented issues, and translated complex information into actionable business insights across multiple industries.

I bring a consistent evaluation mindset: I compare model responses, rank the best output, and provide structured feedback to improve prompts and responses. I assess hallucinations, grammar and tone, image quality, and user intent alignment—helping teams ship higher-quality AI experiences.
