Nihrika Kaladev Software Build -- 2

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.

Deliverables
• Compiled application ready for end users
• Complete, human-readable source code held in a private repository
• Setup / installation guide and brief user manual

Please outline the technology stack you suggest, any relevant past work, and an estimated timeline so we can move forward quickly.
