Hello there! This sounds like a powerful platform that will truly streamline solar project maintenance. I’ve reviewed the SieraSolar visual guide and understand your goal to consolidate and finalize your existing code into deployable apps—web, desktop, and mobile—on a tight timeline and budget. ✨✨✨✨ Comprehensive platform to manage PV solar maintenance across web, desktop, and mobile with sync, scheduling, contracts, and BI dashboards ✨✨✨✨ Key Points: multi-platform suite, desktop/web/mobile apps, contract scheduling, service tracking, AI integration, user panels, payment tracking, dashboard KPIs To execute this efficiently, I’ll first deploy and polish the web app (React + Django backend) on Vercel or a self-hosted domain with PostgreSQL. This includes UI fixes, contract management, dashboard stats, and secure auth (JWT). Next, I’ll wrap up the desktop app using Python + CustomTkinter, ensuring offline syncing and reporting features. Finally, the mobile app (React Native with Expo) will be completed and tested across devices, with all screens and push notifications polished and functioning. I’ll ensure all features like appointment scheduling, contract generation with e-signatures, and BI dashboards are present and stable. Each app delivery will include source code, licensing, and documentation for future updates. I'm fully on board with the $75 milestone-based delivery plan. Looking forward to collaborating and finalizing SieraSolar together! Best regards, Farhin
