Work Experience

Davivienda Bank

Apprentice – Semillero Nativos Program

I participate in Banco Davivienda’s Semillero Nativos Program under a 12-month training contract that includes a study phase—where I strengthen my knowledge of commercial and financial services through theoretical training provided by SENA—and a practical phase, in which I apply these skills at Banco Davivienda S.A. facilities, collaborating on projects, streamlining customer service processes, managing banking operations, and ensuring compliance with internal regulations.
