Hi, this is a serious multi-module booking system and I’ve worked on custom web apps involving scheduling, role-based access, imports/exports, and dashboard logic. I’m comfortable with Node.js, NestJS, PostgreSQL, React/Next, and I understand the Phase 1 priority here is the booking engine plus admin/host workflows. Based on your posted range, I can come in with an initial fixed bid for a scoped Phase 1 starting point and then expand cleanly from there. If you want, I can also outline the Phase 1 architecture and delivery plan here on the platform.

@melikatfz

Hello, 1. Are you open to adopting any alternate solutions for audio processing in Phase 2? 2. Do you already have a preferred API for handling timezone conversions, or should we implement one? Excited about your booking platform! For this project, I’ll focus on building a robust web scheduling system first, ensuring seamless integration with Google Calendar and Meet. I’ll carefully handle user data isolation to maintain security across different accounts. I'll share relevant examples in chat. Let’s discuss the timeline and cost in detail during a call or chat to ensure it fits perfectly with your vision. Looking forward to mapping out the next steps together. Shoot me a quick message, and we can dive right in!

@Rapha

Hi, I'm Rafael. I focus on automation architecture for Node/NestJS platforms and I’ve read the parts about the rolling-window calendar (today +3 days) with automatic timezone handling (CET, EET, Dhaka) and the admin bulk CSV/Excel import with cross-checking against incoming bookings. A practical approach I’d use is an async import pipeline: normalize emails and E.164 phones, build indexed match keys plus pg_trgm-based fuzzy name checks, and run dedupe jobs in background workers that push host notifications and trigger the Excel/export updates without blocking the UI. What’s the expected maximum rows per import and peak concurrent booking rate so I can size workers and queues? Contact me through Freelancer chat to discuss this project in detail and estimate realistic timing and cost.

@ranjika08

Hello, I build custom platforms rather than template-based sites, so this kind of scheduling and admin system is in my lane. Your requirements around isolated host views, booking windows, Google Meet generation, and dataset matching are clear, and I do have experience with NestJS and PostgreSQL-backed applications. My suggestion would be to treat this bid as the initial Phase 1 build scope within your posted budget and keep Phase 2 as a structured extension. Happy to discuss the implementation approach further through the platform.

Hi - Truong here "PHASE 1 WEB BOOKING ENGINE" — you need reliable scheduling, timezone handling, data matching, and isolated host dashboards before adding the desktop layer I’d build Phase 1 with NestJS + PostgreSQL, using indexed lookups for duplicate matching and strict user/host data isolation. The booking flow would calculate slots in the user’s timezone, store times consistently, and handle blocked slots and Google Meet creation on the server. The important edge case is overlapping bookings across CET, EET, and Dhaka timezones, so availability should be checked against normalized timestamps rather than browser-local times. For Phase 1, should the rolling calendar always show exactly today + the next 3 days, and do hosts control their own blocked slots from the dashboard? Looking forward to working with you.

@vladang

Timezone conversion and concurrent slot claims are the biggest risks in this booking flow. For Phase 1, I’d build the NestJS/PostgreSQL foundation first: account-isolated RBAC, host availability, rolling-window booking, Google Meet creation, imports, cross-checking, notifications, and Excel updates. Duplicate matching should use normalized email/phone fields with indexed lookups, while booking confirmation needs a database constraint or transaction to prevent two candidates claiming the same slot. I’d estimate 3–4 weeks for Phase 1, refined after reviewing your written specs and walkthroughs. Should imported reference data preserve every original row for audit, or only store normalized matching records?

@rosscarter1011

Hi, Multi-timezone booking systems fail when slot availability calculations ignore DST transitions in CET/EET/Dhaka regions. Your rolling-window calendar must anchor all time math to UTC with explicit zone conversion at display time to prevent double-bookings. I structure the NestJS backend with timezone-aware scheduling services validated against IANA zone database edge cases before building the React frontend. Can you confirm whether Phase 1 delivery should include the bulk import cross-checking engine, or can that be deferred to reduce initial complexity?

@mahads31

Having worked on a diverse range of projects across industries, I've accumulated the technical knowledge and problem-solving skills to develop your multi-stage appointment booking platform from phase one to the expanded phase two. My expertise lies in JavaScript and Node.js, with a proficiency in NestJS and PostgreSQL that aligns with your project's requirements. It's worth mentioning my familiarity with Google Calendar/Meet API, SendGrid/Postmark, and exceljs - technologies integral for your app's functioning, which may come in handy during development as well. In terms of prior experience, I have created various scheduling platforms that emphasize data integrity and RBAC access control. Your mention of cross-checking candidate bookings with reference datasets resonates with my work on record-matching engines for duplicate checks across different parameters. The automated data synchronization and email notifications post-booking completion are functionalities I had previously implemented too. Using n8n and AI Automation tools that I have used, your project can leverage better productivity by automating tasks like bulk importing system and scheduled meeting alerts via WhatsApp and Push Notifications. Choosing me as your technology partner means you're opting for clarity, strategy, and execution at every stage of development for a product that lasts. Look forward to collaborating!

@LeadForce1

Hi, I'm Luigi from Toronto. "Node.js + React + Electron Stack with PostgreSQL" - you need a booking system that handles timezones, duplicates, and desktop automation. This is a full-stack build with three layers. The backend runs on Node.js with PostgreSQL - I'll index email, phone, and name fields for fast duplicate checks when admins import CSVs or candidates book slots. The web frontend uses React with Tailwind for clean dashboards where hosts see their slots and admins manage everything. The rolling calendar will respect CET, EET, and Dhaka timezones automatically. For the desktop client, I'll use Electron with TypeScript. It will handle background screen capture at intervals, compress locally, and upload to S3. The audio recording will include noise suppression. I'll integrate Firebase for push notifications and WhatsApp for reminders. One technical decision: I'd recommend using NestJS for the backend structure. It gives you clear separation between modules - booking, admin, import, and notifications - which makes Phase 2 expansion much cleaner. The API will be versioned so the web app and desktop client can update independently. Are the CSV/Excel import formats already defined, or should I design the schema based on the fields you need to cross-check? Looking forward to working with you. Luigi Tedy
