What I'm looking for

I seek roles combining AI model training and Fintech CX where I can apply regulatory knowledge, improve user experiences, and grow into leadership in AI safety or customer success.

I am a bilingual Fintech professional with over two years' experience in high-volume online customer service and AI training. I have refined AI model behavior using RLHF, performed real-time evaluations and prompt engineering, and managed regional onboarding and identity validation across multiple Latin American markets while consistently exceeding KPIs and CSAT targets.

I hold a B.A. in Business Administration (Cum Laude) and a Diploma in Capital Markets, Fintech & Crypto, and I achieved full English proficiency through an IELTS C1 certification and two years working in Australia. I bring regulatory awareness, accuracy handling 120+ daily cases via Salesforce, and a commitment to ethical, legally compliant AI development.
