What I'm looking for

I seek a remote or hybrid role where I can lead revenue operations or sales development, scale teams, optimize KPIs, and drive measurable growth in an inclusive, data-driven environment.

I am a Sales Development and Revenue Operations manager with experience driving B2C and B2B revenue growth, improving retention, and scaling high-volume operations. I lead and coach cross-functional teams, having overseen 100+ staff and multiple store launches across LATAM.

My background in psychology and consultative communication enables strong customer engagement, negotiation, and team development. I combine people leadership with data-driven KPI analysis, forecasting, and reporting to optimize pipeline and performance.

At D1 SAS I led pricing strategy, product positioning, and coaching that produced a 9.5% YoY sales increase and the region's lowest employee turnover in Q2 2025. I supported seven new store launches and produced monthly reports on KPIs, EBITDA, shrinkage, and cannibalization.

Previously I delivered corporate English training at Berlitz Colombia, increasing client retention 50% in 2023 and earning MVP Instructor recognition, and I achieved top sales performance at Teleperformance through targeted outbound strategies and conversion initiatives.
