Full-Stack Booking Platform & Desktop Client

@crtvecode

BOOKING STACK The project requires a solid backend for the web booking system and those responsive desktop clients. I see the need for reliable integration with Google Calendar and automated link generation, which can be kind of tricky without proper OAuth2 handling. And I’ll focus on setting up the Node.js and NestJS backend to manage bookings, and make sure smooth communication with PostgreSQL. For the desktop client, I can go ahead and implement the Electron framework to handle notifications and session captures efficiently. I can complete the work first, allowing you to test everything before any payment or award. You’ll only create the milestone once you’re satisfied with the results, I’m ready to start immediately and will deliver this for 62 USD.

Hi, BOOKING STACK This project needs a solid backend foundation to keep availability, bookings, timezone handling, Google Meet links, admin imports, and Excel sync aligned from day one. I would first design the booking logic, host rules, and sync flow to prevent data drift and integration issues later. For Phase 1, I’d build the core booking calendar, host availability rules, OAuth2 calendar integration, and a stable NestJS/PostgreSQL database structure. I’d then add admin ingestion tools and automated sync jobs with validation, logging, and audit-friendly error handling to keep the system reliable as usage grows. For Phase 2, I can implement the desktop agent with a clean event/capture flow, offline caching, and secure cloud sync to S3. I’ll keep the web and desktop systems aligned with shared TypeScript models and consistent API contracts. I can review the scope with you in Freelancer chat or a video call between 11 AM and 8 PM IST. One quick question: should Phase 1 support only one host per booking, or do you need multi-host/session assignment from the start? Regards, Ghanu & Samir KESHAV INFOTECH

Hi, The project requires a robust full-stack system integrating scheduling, multi-timezone support, and seamless desktop-cloud synchronization. The main engineering challenge lies in ensuring reliable offline caching and conflict-free sync between the desktop client and cloud storage. I usually structure backend services with clear separation between booking logic, availability management, and external API integrations like Google Calendar. My experience customizing complex digital products and implementing CRM workflows provides a strong foundation for this. I recommend separating the web platform and desktop client development to isolate concerns and optimize sync mechanisms. Handling OAuth2 securely for Google APIs and WhatsApp Business is critical. Ensuring data consistency during offline mode and sync requires careful conflict resolution strategies and incremental updates. Systems must be designed for long-term production use with clear documentation and maintainability. I can provide a detailed architecture outline covering ingestion, booking orchestration, and desktop sync flow. Thanks, Hercules

@denisSolution

Hi, I'm Denis, a full-stack developer who has built several booking and scheduling systems with calendar integrations, multi-timezone logic, and real-time availability management. I understand your needs: a web platform for session bookings with timezone handling, automatic Google Meet generation, and admin availability tools, followed by a Phase 2 desktop client that captures meeting data locally and syncs to the cloud. The key challenge is keeping everything synchronized across web, desktop, and external services while handling offline scenarios. I've worked on similar systems requiring multiple interfaces to stay consistent with backend state and third-party API integrations with careful error handling. Timezone and availability logic must be bulletproof since booking conflicts directly impact users. My approach: start with a solid NestJS and PostgreSQL backend handling availability queries, timezone conversions, and integrations cleanly. Build a React frontend for smooth booking with proper state management. Once stable, the Electron desktop client becomes straightforward since it consumes the same APIs. I'll carefully build the offline caching layer to avoid sync conflicts. Key considerations: Google Calendar API rate limits and OAuth token refresh need transparent handling. I'd also clarify the exact data model for sessions and availability windows early, as this shapes everything downstream. Phase 1 typically takes four to six weeks depending on complexity. I can

@shayankhan333

BOOKING STACK For Phase 1 I'll build the NestJS/Postgres booking core with rolling availability, per-host Google Meet via OAuth2, and the Excel sync into your admin ingestion tools. Multi-timezone bugs usually trace back to storing local times instead of UTC with a separate zone field, so the schema handles that first. Realistic first working build for Phase 1: about 3 to 4 weeks. Portfolio covers Electron desktop utilities and Node scheduling systems: https://www.freelancer.com/u/shayankhan333 1) Is WhatsApp Business API on an existing BSP? 2) One Google Workspace or per-host OAuth? Message me and we can lock the plan down. Shayan

@opeyemia615

BOOKING STACK Your multi-stage platform requires a rolling-window booking calendar with multi-timezone management, Google Meet OAuth integration, admin data ingestion, Excel sync, and a Windows desktop agent for notifications and offline session capture. The calendar sync with Google's OAuth and the desktop client's offline caching are the two features that will require the most careful architecture. I would build Phase 1 with NestJS backend, PostgreSQL, React frontend, and Google Calendar API integration. Phase 2 would be an Electron desktop client with background session capture and S3 sync. I would implement webhooks for real-time updates and automated email/SMS notifications. I have built custom scheduling systems with Google Calendar integration and desktop utilities with offline sync. 1. For the desktop client's session capture, should it monitor system activity or user-selected application windows, and does it need to capture periodically or only during active meetings? 2. For admin data ingestion, do you need CSV import, manual entry, or API-based sync from an external system like Excel spreadsheets with specific columns? Reply with those answers and I can propose the Phase 1 timeline. Best regards, Opeyemi
