About me

From backend development to marketing strategy, I create customer experiences end-to-end.

I see myself as a designer of systems and experiences who understands development, marketing, and customer support together. This broad perspective is why I am drawn to marketing automation and the way it can improve customer journeys.

I have managed and delivered successful eCommerce marketing campaigns by combining technical knowledge with strategic thinking.

With a strong focus on data analysis and customer-oriented development, I know how to identify the right direction and turn it into action.

I also enjoy taking on new technologies, platforms, and programming languages. I adapt quickly, grow continuously, and value feedback as an opportunity to innovate.

Problem solver: Proactive, passionate, and driven.
Team player: Strong collaboration skills honed in marketing.
Lifelong learner: Eager to embrace new challenges, adapt quickly.
