I'm sorry, but it seems there are no specific projects, clients, or systems provided in your request. Therefore, I cannot describe what I helped my clients with in the past six months. However, in a broader sense, I specialize in solving complex issues for theaters, venues, festivals, cinemas, and organizations selling tickets online, focusing on integrating WordPress websites with ticketing systems. Further, over the past years, I've offered my expertise to ensure seamless system integration, always delivering efficient and cost-effective solutions to various challenges my clients face in the ticketing and entertainment industry.
