Elampki.pl is the flagship store of the company, as well as one of the biggest lighting eCommerce stores in Poland that serves several thousands of customers daily.
I designed a separate channel of communication for wholesale customers, including a web application that allows them to have a streamlined ordering process. I also improved specific landing pages.

Nowodvorski Online

Nowodvorski Online is a secondary store of the company, focused on vendor products from a specific manufacturer.
I designed, built, and improved multiple of the main online store pages, through rigorous A/B testing and user behavior monitoring using tools such as heatmaps and user interaction recordings. I also implemented a full, multi-supplier product availability system that updates live, taking into account foreign warehouse stocks and combining them with the store's own warehouse system. I also worked alongside SEO specialists to improve the site's visibility in search engines.

Personal Portfolio and Blog

A static portfolio website built with GatsbyJS and TypeScript, containerized with Docker, and deployed to a Kubernetes cluster using GitLab CI/CD.
I was the only developer for the project—designing, architecting, and coding it all from the front end to deployment. I also worked on the improvement of the deployment processes, making them fully automatic from the moment the code is committed to the repository, through the use of GitLab CI and GitLab runners deployed inside the cluster.
