Building E-commerce Excellence

Marek Zimmermann - E-commerce Manager

I'm Marek, an E-commerce Manager with over 9 years of experience working with companies of all sizes - from small to established brands. Currently, I manage online stores for Helikon-Tex and Direct Action in the fashion industry.

My focus? Making e-commerce operations run smoothly. I handle multiple domains - from store management and team coordination to tech implementation and data analysis. I've worked with B2C, D2C, and B2B2C models, including cross-border sales, so I understand the challenges each brings.

I'm particularly into the technical side - whether it's implementing a new platform, planning features, or translating tech requirements into business language. I like testing new ideas, analyzing data, and continuously improving how things work.

I believe in clear communication, proactive problem-solving, and making data-driven decisions. Planning is important, but so is adapting when things change.

Outside of work, I'm into calisthenics and combat sports. I also enjoy business and tech podcasts.

Analytics

I work with analytics daily-tracking metrics, testing hypotheses, and using data to make better decisions. When data isn't available, I rely on best practices and risk assessment. I make sure the team understands how their work impacts the numbers.
