At SESI - Serviço Social da Indústria, I organize schedules, lesson planning, and records, and analyze performance data to support action plans that improved outcomes by up to 60%. I also provide ongoing support to students and assist with international communication initiatives.

At Editora Belvedere, I designed and organized three book materials within two months, preparing presentations and support documents and checking them for accuracy and consistency.

Earlier, as Department Manager at Minds English School, I handled administrative operations, recruitment, and onboarding. I helped increase new client acquisition by 25% per semester, maintained a 90% retention rate, and reduced client complaints by 30% through improved communication and response times.
