    I need a skilled developer to turn the Nihrika Kaladev concept into a fully-functioning piece of software. The core request is straight software development—no web or mobile layer at this stage—so your focus will be on architecting, coding, and testing the main application itself. The exact operating system is still open; I’m happy to hear your recommendations on whether Windows, macOS, Linux, or a cross-platform approach would serve the project best. Whichever route we take, clean, well-documented code and a straightforward build process are essential.

The assistant must be able to listen to callers, understand their intent, speak back naturally, and—most importantly—handle two core tasks for me: • Answer customer inquiries in real time for the serivces i provide • Schedule appointments directly into a calendar or booking system design considerations, hardware requirements as well as training and setup guidance (I will build the hardware myself and learn and understand the software design).
