What I'm looking for

I seek a client-facing or data-focused role utilizing AI dataset labeling and clinical data management, offering growth, collaboration, and meaningful impact.

I am a dependable analyst with hands-on experience labeling AI datasets and managing client relationships across Spain, LATAM and the UK. I have worked directly with more than 50 customers, creating sales funnels and scheduling meetings to drive adoption of software solutions.

My background includes clinical trials data management where I performed eCRF data entry, quality assurance checks, and coordinated site contacts and on-site visits for Spain-based trials. I combine attention to detail with strong organizational skills to ensure data integrity and regulatory compliance.

Earlier roles in real estate operations and hair studio management strengthened my customer service, operations oversight, and booking/ticketing system experience. I routinely handled planning, maintenance coordination, payments reconciliation and day-to-day operations.

I communicate clearly in Spanish, Catalan and English (B2), and I am proficient with CVAT and Labelme, Microsoft Office, Adobe Photoshop basics, ChatGPT prompt engineering basics, and common video-conferencing and calendar tools. I seek roles where I can apply AI dataset expertise and client-facing skills to deliver measurable business outcomes.
