High-Performance Shopify Stores. Data-Driven Decisions. Engineering Precision.

If your Shopify store is fast but doesn’t convert or if you have traffic but no clarity on your numbers, you don’t just need a "web designer"—you need a technical partner who understands the math behind the sales.

I am an Engineer with a Master’s in Data Science, specializing in transforming Shopify stores into high-converting, automated machines. I bridge the gap between "it looks good" and "it performs at 100%."

How I add value to your business:

⚡ Speed & Performance: I don't just use apps; I optimize code. I recently achieved a 91+ Performance Score and 100 SEO Score on complex stores, ensuring lightning-fast load times.

📊 Data-Driven CRO: I analyze your store’s bottlenecks using my engineering background. No guessing—just actionable improvements to your funnel to increase ROI.

🐍 Python & Automation: I can build custom scripts to automate inventory, handle data migrations, or integrate Shopify with external tools, saving you hours of manual work.

🛠️ Tech Support & Bug Fixing: Whether it's a broken checkout or a theme glitch, I solve technical debt with clean, scalable solutions.

Why work with me?

Multilingual: Fluent in English, Spanish and German, allowing me to help brands scale in the US and DACH markets.

Transparency: I don’t just fix things; I explain how and why so you can manage your store with confidence.

Reliability: As an engineer, I live by deadlines and structured processes.
