Dear Client, I read "Legacy Enterprise Software Acquisition" carefully and understand you are looking for a full-stack developer who can handle both application development and AI integration. I have experience with C Programming, Java, C# Programming, C++ Programming, Ruby and can work across the complete stack — frontend, backend, APIs, databases, authentication, third-party integrations and AI features. I can build scalable applications using modern technologies while keeping the codebase maintainable and production-ready. A few quick questions: Which AI models/APIs are you currently planning to use? Is there an existing application/codebase, or will the project be built from scratch? Thanks & Regards, Deepak
