Common Questions

What hiring managers ask most often

What does Daniel Bereza do?

Daniel is a Technical Specialist who builds and improves ecommerce storefronts on WordPress and WooCommerce. His work covers custom themes, custom plugins, product and landing pages, and checkout flows, with a focus on turning more of a store's existing visitors into paying customers.

How much WooCommerce experience does he have?

He has more than six years of professional WordPress and WooCommerce work. Most of it is custom development rather than page-builder assembly, including themes written from scratch, purpose-built plugins, and the cart and checkout areas that decide whether a shopper finishes an order.

Does he do conversion rate optimization and A/B testing?

Yes. He works from a stated hypothesis, changes one variable at a time, runs both versions side by side, and reads the result before deciding. That covers product pages, landing pages and checkout, measured against conversion rate rather than against opinion.

What technologies does he work in?

PHP, JavaScript, HTML and CSS, with MySQL and REST API development. On the operations side he uses Git for version control and staging environments for testing, and he works on site speed and Core Web Vitals including LCP, INP and cumulative layout shift.

Where is he based, and does he work remotely?

He is based in Hartford County, Connecticut, and works remotely with teams across the United States. He has experience collaborating with marketing and design colleagues remotely, including building from Figma files and reporting results to people who are not developers.

What is his educational background?

He holds a Bachelor of Science in Computer Science from Central Connecticut State University in New Britain, Connecticut. He was also named a Local Business Person of the Year in the Alignable 2024 awards and has been featured in Bold Journey and CanvasRebel magazines.
