About Me

Whoever you are, your presence here means that I may have (or be) something you are looking for. But before we get down to business, let me introduce myself.

My name is Sara Kozińska. I was born on 21.10.1987 in Warsaw, Poland. Currently I live in sunny Barcelona, Spain, where I live with my stubborn (but still cute) French bulldog Lilo.

Since I can remember I have 3 passions: animals, boards (skateboard, snowboard, wakeboard, surfing...) and computers. To this day they are all part of my life. Over time, other interesting things were added, such as cooking (Mexican and Asian cuisine), drumming, music, filmmaking, traveling and self-development (spiritual development).


I have 15+ years of experience in code development industry!!!

Yes, I have been speaking with computers for over 15 years! That's over 500,000 hours of work, and I dare your company to use it as a leverage in your business!

I started programming in high school with Action Script (Macromedia Flash) and basic HTML / CSS. From there I dived into the world of content management systems such as Joomla, PrestaShop, Magento, Drupal, and Shopify which led to my specialization in WordPress development (WordPress powers 65.2% of all websites using any content management system).

Working with such a wide range of clients and tools has given me the opportunity to learn the most modern programming languages and libraries.

Considering myself as a WordPress developer I've worked with the most popular Page Builders / Themes (Avada, Divi, Elementor...), and quite a large amount of well-known WP plugins, so I have the ability to detect the most common issues/bugs and fix them in a very quick time. Coding custom themes, I was often creating (on the base of ACF PRO's Flexible Content field) custom page builders, tailoring them to client needs and experience. Now my switch is definitely to creating custom Gutenberg blocks.

My strongest skill is in custom code and optimization. I create new themes, plugins, and blocks from scratch, and I am always looking for the most efficient, modern solutions for my projects.

I am most enthusiastic at the moment about:
- WordPress Development: Gutenberg, Fullsite editing, headless WP (REACT, VUE, TypeScript, Faust.js);
- Jamstack: [REACT / VUE.js / TypeScript / ...] + [ / Prismic / Netlify / ...];
- GSAP (GreenSock), ANIME.JS
- work with AI solutions, creating AI solutions,
- Node.js (learning).

I'm not asking you to take my word for it; I challenge you to take my references into account, or even better, let me prove myself in practice!

INCREO.NO Sigrid Anita Rømma Project Manager,

Sara is detail-oriented, self-driven and during the process she demonstrated great skills and problem-solving abilities. She approaches challenges with a positive attitude and an analytical mindset, consistently finding good solutions. She follows instructions and seeks clarification when needed, ensuring tasks are executed accurately and efficiently.

I would recommend Sara for similar projects or roles.

The TEFL Academy Rhyan O'Sullivan Managing Director, The TEFL Academy

Sara built our new website, which was a particularly complicated multi-site wordpress project, with many custom build components. Sara has done an excellent job and we are extremely happy with the website and the work Sara completed for us.

A large part of Sara's role with us was coordinating with our Systems Architect and Designer to facilitate the completion of company-wide goals through web development. Sara managed this very well and exceeded our expectations on every issue she completed for us. Sara was always thoughtful and considerate, an excellent team player who can also work independently.

Integrated Mobile Marketing Chad Middleton Vice President, Integrated Mobile Marketing

Sara has been a part of a number of complex WordPress-based projects, and she plays a pivotal role in ensuring that they are successful. She has grasped most modern WordPress standards, and her quick learning capability helps her code both custom themes and plugins with great quality.

I have had the opportunity to work with Sara Kozinska directly and I can attest that she is an excellent professional and rewarding to work with. She is a great team worker, and on many occasions demonstrated innovative qualities when problems occur.
