Summary

I’m a highly analytical and customer-centric professional with over a decade of progressive experience in Digital Product Operations, Customer Success, Product Owner and Quality Assurance, gained primarily during 10+ years at Claro Paraguay within the telecom and digital services sector. My core strength lies in managing the full product lifecycle, ensuring operational excellence, reliability, and user trust in complex digital environments.

I excel at bridging the gap between technical teams and customer needs, anticipating friction points and implementing solutions that enhance product adoption and long-term retention. My background in QA Testing and Product Ownership enables me to translate user insights into measurable product improvements and process optimization.

In parallel, I’ve built a strong foundation in the Fintech and Crypto landscapes, including U.S. stock markets, options trading, blockchain ecosystems, and P2P operations. This experience allows me to connect deeply with users of financial and payment platforms, providing value-driven, informed, and empathetic support.

Fluent in Spanish (native) and English (advanced). I thrive in remote, fast-paced environments and aim to contribute my hybrid expertise—combining technical precision with financial insight—to help innovative teams deliver exceptional user experiences and sustainable growth.
