Esports community and marketing operator at Flower Cat League, producing events and helping overhaul player rewards.
ColombiaWhat I'm looking for
At Flower Cat League, I direct social media and marketing and produce events for its Clash Royale community. I also helped overhaul the rewards system into a token shop where players can redeem tokens earned through wins.
I built Trialworkz, an Overwatch tournament community, and lead its marketing and PR while coordinating the developers building its tournament bot and website. Its Discord community passed 50 members in the first month, and we ran a test tournament.
Across gaming and esports, I’ve coached Overwatch players, represented Colombia at the Overwatch World Cup, and worked in QA, customer support, sales and marketing. I also ran four Meta campaigns for a real estate client, generating 196 WhatsApp conversations on about US$85 in ad spend; the listing sold.
