Dear, client!
As both a skilled programmer and experienced team lead, I am well-equipped to create the server based Twitter monitoring and reply bot you're looking for. My expertise in C# Programming, JavaScript, PHP, and Software Architecture are directly relevant to this project's needs.
Regarding your project's need for limitations on replies per hour, day, and week on a specific account, I can assure you my solution will include these restrictions. In fact, anticipation of such potential constraints is ingrained in my design process. I would build your bot with careful planning and adherence to Twitter's API rate limits and best practices to ensure we don't breach any boundaries.
My 9-year experience working in technical teams augmented by my leadership background means that communication with you as the client during this project will be seamless and efficient. To achieve the desired results, I will work closely with you to understand your specific preferences for monitoring and replying to tweets on your Twitter account. I look forward to having the opportunity to demonstrate my skills for your project.
