Customer Success & Ops Specialist | Travel, Hospitality & Data Entry

International Customer Success, Operations & Data Entry Specialist with 4+ years of experience supporting global customers and B2B travel partners in fast-paced travel and hospitality environments. I specialize in managing end-to-end customer interactions across phone, email, live chat, and data entry tasks, including bookings, cancellations, payments, refunds, escalations, and complex operational cases. I consistently maintain a strong focus on customer satisfaction, service quality, accuracy, and efficient resolution in high-volume environments. In my recent role as a Tier 2 Customer Success Expert at Walks Agency (Hornblower), I handled complex escalations, chargebacks, and vendor-related issues while maintaining 90%+ CSAT. I also collaborated closely with operations teams, suppliers, and partners to streamline workflows, resolve service issues, and improve overall support efficiency. I also have experience supporting cruise and shore excursion planning operations with Venture Ashore, assisting in the coordination, management, customer support, and data handling of cruise excursions and travel itineraries, ensuring smooth planning and high-quality service delivery for international travelers. I am experienced with CRM and customer support tools including Salesforce, Ventrata, Anchor, Talkdesk, Confluence, Calabrio, and Sprout Social. I am also a fast learner when it comes to new CRM systems and technologies, quickly adapting to new tools and processes. Additionally, I have worked in remote and high-volume support environments, demonstrating adaptability, multitasking abilities, emotional intelligence, strong attention to detail, and organizational skills under pressure. Fluent in English and native Spanish, I bring strong communication skills, emotional intelligence, and a customer-first mindset, with a passion for delivering seamless support experiences for international clients and partners.
