Krasen did an awesome job! We had some difficulties, mainly caused by me not taking the right approach from the start. But this couldn't stop Krasen, he kept going until the work was done. Much respect for the man! I will definitely hire again and recommend him to others. Thank you :)

Krasen built a custom ACF-based WordPress homepage for us and handled multiple rounds of refinement professionally. He was responsive, provided useful technical explanations, and delivered helpful handoff documentation, including QA and editing notes. The final homepage is a much stronger foundation than what we had before, and we appreciate his work and support throughout the project.
