Hi, I’m Sergio Constantin, an administrative professional with extensive experience supporting executives and public-sector teams in Argentina. I have provided executive assistance and payroll management for judges and magistrates, handling emails, logistics, schedules, and HR/salary processes. I have also developed and implemented marketing strategies as a freelance media buyer, managing social advertising campaigns on Meta, Google, and TikTok with a focus on growth and ROI, including data analysis to optimize campaign performance. I am based in Argentina and planning to relocate to Germany in 2025. I am primarily focused on administration, but I am also passionate about music, cooking, cryptocurrencies, and marketing, and I enjoy applying creative thinking across diverse projects.…Hi, I’m Sergio Constantin, an administrative professional with extensive experience supporting executives and public-sector teams in Argentina.
