## Selected work
- Asunciónico 2026 (Paraguay's largest music festival, produced by G5 Pro): FOMO and pre-sale content outperformed the rest (+19% conversion rate, +4% ROAS, −4% cost per ticket vs. other content); spend was concentrated on it and the campaign reached ~8K tickets sold online and 80x ROAS.
- monchis (food delivery): analysis by day and time slot found demand concentrated at weekends and dinner time, with the lowest cost per order on Friday to Sunday; shifting spend to those moments gave +62% orders for the same spend and −38% cost per order.
- Personal (telecom): Monday–Thursday leads converted 20% better than Friday–Sunday; reallocating spend, validated with a test, gave +40% leads, −26% acquisition cost, +16% closed contracts.
- Personal (telecom): Skai made daily AI micro-optimisations on Meta and Google conversion campaigns; matching platform results with the client's closed contracts showed +33% leads, +32% closed contracts, +258% Meta conversion rate.
- Nestlé Business Solutions x Maggi Chile: two years of digital conversation and retail trends turned into consumption patterns, shared with local marketing as input for product planning in case the instant soups were launched.
- TaDa (beverage delivery app): nationwide survey of ~1,000 people (designed, processed and analysed) validated the value proposition and found habit was the main barrier, which led to the "Apptualizate" concept; influencer conversions measured with coupons, up to 8x ROAS for the channel.
- ueno bank (digital bank, strategic partner that brought Shakira to Paraguay): weekly tracking of format, creative and message tests for the second Asunción date; 734K link clicks.
- Regional influencer benchmark: 3 years of data across 4 LATAM countries; its reach and cost values were adopted to evaluate and estimate campaigns.
- Candydatos / D1ANA (2022–2023, electoral context): supported, as a junior analyst in a team of two, the tracking and cross-analysis of digital data on 15 presidential candidates.
- Reporting for Sesame Street LATAM and Roku (Chile, Mexico, Colombia), with the BI team's top satisfaction scores.
- Social media management: content publishing and moderation of up to 1K interactions/month with sentiment analysis for L'Oréal Luxe, Danone and FNC; wrote the process playbooks.
