01 / about me

Marcin
Krzyżanowski.

I work with online stores and servers every day.

I build stores with Magento 2, Shopify, WooCommerce and PrestaShop. For Magento projects, I mainly use Magento Open Source/MageOS and Hyvä. I also handle ongoing development and optimisation.

I work on both code and infrastructure. When something breaks or runs too slowly, I investigate logs, databases, Varnish, Redis and server configuration. I also integrate and configure external search services such as Algolia.

How I
can help.

Development, optimisation
and maintenance.

Online store development

I help launch stores on Magento 2 (Magento Open Source/MageOS) with Hyvä, Shopify, WooCommerce or PrestaShop. After launch, I handle further development and integrations.

Store performance optimisation

I investigate what slows a store down. I use Blackfire and New Relic to find the code and database queries that take the most time. I also check caching and server configuration, then compare results after making changes.
