1. PROJECT OVERVIEW & SCOPE The Goal is to engineer a custom, proprietary Omnichannel Real Estate CRM & AI Marketing Automation Platform from scratch. The system will unify marketing and sales leads from all major digital touchpoints, automate communication via RAG-driven Conversational AI, feature built-in Voice over Wi-Fi (VoWiFi), provide executive analytics, and host an external B2B Broker Portal. ________________________________________ 2. CORE FUNCTIONAL REQUIREMENTS 2.1 Unified Communications & Customer 360° CRM • Omnichannel Data Ingestion: Real-time data and message ingestion from: o Two (2) Corporate Websites o Messaging Channels: LINE OA, WhatsApp Business API, Telegram o Paid & Organic Social: TikTok, Instagram, Facebook Ads, Google SEO, Google My Business • Smart Routing Engine: Matrix-based lead assignment. Dynamically route leads to internal agents based on language proficiency or inquiry type. Include an automated, time-based escalation protocol: if an assigned agent fails to respond within a set window, the lead auto-forwards to the next available team member. • Role-Based Access Control (RBAC): Distinct permissions, feature access, and dashboard views for Sales Agents, Managers, and Executives. • VoWiFi Integration: Native Voice over Wi-Fi capabilities for crisp, browser-based calling, native call logging, and automatic call recording mapped directly to the customer's chronological timeline. • Database Essentials: Automated data deduplication, visual drag-and-drop sales pipelines, robust deal/task management, and push notifications/reminders. 2.2 Embedded Marketing & Conversational AI Software • Market Research & Competitor AI: Automated scraping and analyzer engine that monitors direct real estate competitors, analyzes our active online footprints, and generates strategic recommendations. • Content Generation & Hyper-Personalization: Embedded Gen-AI tools to generate/optimize ad copy and dynamically deliver tailored property recommendations based on user browsing behavior. • Marketing Workflow Automation: Zero-manual-intervention systems for target audience segmentation, automated email/message scheduling, ad bidding optimizations, and continuous A/B testing. • Conversational Customer AI: Custom RAG-based AI agents deployed across LINE, WhatsApp, Web, and Phone to automatically handle 50-100 daily inquiries regarding project layouts, prices, and unit availability. 2.3 Executive Reporting & Analytics Suite • Real-time Dashboards: Absolute visibility into daily activities broken down by individual member, team, and organizational role. • Cross-Functional Tracking: Unified reporting across online marketing performance, paid ad spend/ROI, organic sales pipelines, and customer support metrics. 2.4 B2B Broker & External Agent Portal • External Commission Tracking: Digital dashboard to manage commission tiers, visual payout structures, and status updates for third-party agencies and independent brokers. • Shared Collateral Vault: A central, secure hub for external brokers to download authorized project brochures, floor plans, high-res renderings, and up-to-date pricing lists. ________________________________________ 3. TECHNICAL ARCHITECTURE & COMPLIANCE • Thailand PDPA Compliance: Strict adherence to the Thailand Personal Data Protection Act. Mandatory features include explicit consent logging, secure data encryption at rest and in transit, automated data retention/purging workflows, and an instant "Right to be Forgotten" protocol. • Hybrid Deployment Infrastructure: Core application layers, web entry points, and AI APIs can utilize secure cloud instances (e.g., AWS/GCP Singapore or Thailand regions). However, all sensitive customer databases, call recordings, and PII (Personally Identifiable Information) must be hosted locally on our on-premise servers via secure, private tunneling. • API-First Extensibility: The platform must expose clean, securely documented REST/GraphQL APIs (hooks) allowing internal legacy software and approved third-party applications to connect seamlessly. ________________________________________ 4. INTELLECTUAL PROPERTY & OWNERSHIP • 100% Full IP Transfer: Upon completion, 100% of all intellectual property, custom source code, algorithms, UI/UX designs, data models, and deployment configurations will belong exclusively to our company. White-labeling or building custom wrappers on top of existing commercial CRMs (e.g., HubSpot, Zoho) is strictly prohibited. ________________________________________ 5. Conversational Customer AI (RAG-Driven) • Retrieval-Augmented Generation (RAG): The LLM must connect directly to your local database of project layouts, pricing lists, and real-time unit availability. This prevents "hallucinations" when answering customer questions. • Omnichannel Deployment: A single unified LLM backend must handle 50-100 daily incoming inquiries seamlessly across LINE OA, WhatsApp Business API, and your corporate websites. • Intent Recognition & Escalation: The model must detect when a lead is highly qualified or frustrated, immediately handing the conversation over to a human agent via your smart routing matrix. Embedded Marketing & Content Generation AI • Hyper-Personalized Recommendation Engine: An LLM module that analyzes a customer’s website browsing history and automatically writes tailored property pitch summaries matching their exact behavioral profile. • Ad Copy Optimization: Integrated Gen-AI tools built directly into your sales agent dashboard to instantly generate and optimize ad copy for TikTok, Instagram, and Facebook Ads. Market Research & Competitor Intelligence AI • Scraping & Synthesizing Engine: An autonomous LLM agent tasked with monitoring direct real estate competitors by scraping their public online footprints. • Strategic Recommender: The model must process competitor pricing and promotion data to automatically generate strategic marketing suggestions for your executives. Technical Architecture & Data Constraints for the LLMs • Hybrid Deployment Data Privacy: Because your system must strictly comply with Thailand's PDPA, the LLM APIs can sit on regional cloud servers (e.g., AWS Singapore), but they must access PII and sensitive data through secure private tunneling to your on-premise infrastructure. No customer PII can be used to train public open-source models. 6. URGENT PHASED DEVELOPMENT CLAUSE This project is a high-priority, urgent initiative. To accelerate time-to-market and mitigate deployment risks, development teams must structure their proposals into logical, independent delivery phases.

Hi there, I will deliver your multichannel conversational AI platform with the WebSocket hub, eight channel connectors (LINE OA, WhatsApp Business, Messenger, Telegram, Instagram, Google Business, TikTok, SEO capture), and the four language enquiry to reservation flow, all containerised and ready for production. On a similar project, structuring the connector layer as isolated modules let us add two new channels in under a day each, which is exactly the bolt on flexibility your architecture needs. Questions: 1) Which four languages are required for the conversational flows, and do you already have translation assets or will the CMS handle that from scratch? 2) For the Zoho sync, are you on Zoho CRM Plus or a specific edition? This affects which API tier we target for bidirectional data writes. Looking forward to potentially working together. Thanks, Kamran

Hello, You’re not just building chat flows , you’re building the system that prevents leads from slipping through when conversations move across channels, languages, and teams. I can see the hidden risk here: orchestration, not just AI. I’ve built PHP/MySQL, Laravel, API, CRM, and automation-based platforms, and I can help structure the WebSocket hub, connectors, multilingual SSR portal, and admin workflows so the whole pipeline stays reliable and easy to extend. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’d approach this with a containerised backend, clean integration points for Zoho and the channel APIs, structured event logging, and an admin UI for routing, reminders, and analytics. Which framework and database stack do you want for the SSR portal and admin panel? What language stack and framework do you want for the SSR portal and admin panel, and do you already have the Zoho data model mapped? Best regards, Asad

Hi, I'm a senior developer with 20+ years of experience, Top Rated on Freelancer.com with 1,500+ completed projects and a 5-star record, and I've built similar conversational AI systems with real-time WebSocket APIs, multichannel connectors, and automated workflows. I'll implement the core AI agent in Java for high-throughput WebSocket handling, a PHP/Laravel backend for the SSR portal with multilingual CMS and media pipeline, and Node.js services for the channel connectors. The database will be PostgreSQL with Redis for session caching and intent tracking. For automation, I'll build a rule engine in the admin UI with configurable triggers for notifications and reports. The Zoho integration will use their REST API with OAuth2 for bidirectional sync. I'll containerise everything with Docker and deploy to AWS with RDS for the database, EC2 for compute, and CloudFront for media delivery. Load testing will ensure real-time messaging across LINE, WhatsApp, and Telegram, while a CI/CD pipeline will handle deployments with zero downtime. I can start immediately.

The WebSocket layer and connector architecture are the parts I'd get right first, because once LINE OA, WhatsApp, Telegram, Zoho, and your in-house apps are all exchanging live events, changing that foundation later becomes expensive. I'd build this as a modular platform where each messaging channel is isolated behind the same interface, so adding future channels doesn't require rewriting the core conversation engine. The WebSocket hub would handle live messaging and remote-tool communication, while background workers process catalog sync, notifications, reports, and analytics without blocking user conversations. For Zoho, I'd treat bidirectional sync as an event-driven process with conflict handling so updates from either side remain consistent. The multilingual enquiry-to-reservation flow, user assignment by language and skills, and structured interaction logging should all share the same data model to keep reporting and CRM integration straightforward. One question: do you already have a preferred AI model/provider for both text and real-time voice, or should that be part of the implementation?

Hi, I can build the real-time WebSocket layer and multichannel connectors to keep your AI responsive across LINE, WhatsApp, and Telegram without lag. I recently integrated a similar conversational stack with Node.js and WebSocket for a logistics chatbot, where we had to handle fluctuating message rates and keep the session state consistent. I'd approach this using a horizontally-scalable Node.js WebSocket hub with channel-specific adapters because it keeps the system lightweight while avoiding complex message routing. The biggest improvement will come from standardising the outbound API layer so new channels can be added without touching the core logic. I always deploy changes in isolated containers and run load tests against the WebSocket endpoints to catch bottlenecks before they hit production. The goal is a reliable system that scales with your traffic and reduces manual channel management. If the setup matches your needs, I can start right now. Thanks, Denis

Building this multichannel conversational AI requires strong focus on seamless real-time messaging, smooth integration, and user-friendly admin controls. I’ve helped a client in retail set up a multilingual chatbot with live WebSocket syncing to their CRM and marketing channels, which gave them near-instant customer response and accurate lead tracking. For your project, I’d start by designing a secure and scalable WebSocket layer that supports live chat and catalog syncing with minimal lag. Have you considered WebSocket keep-alive strategies for handling intermittent network issues from mobile users? Also, for the multilingual CMS, will content updates need to auto-propagate to all channels or be customized per platform? The native connectors can be built with a modular pattern so future channels plug in easily without core rewrites. I’m comfortable setting up automation workflows inside the admin UI that push real-time notifications and generate reports, based on triggers from new leads or task completions. Database schemas would store every interaction and metric in structured form for analysis, along with APIs for smooth Zoho integration. I’ll deliver containerized code with SSR pages, a tested WebSocket hub, live demo flows, sample integration scripts, and deployment docs. Ready to get started and show progress quickly with a working enquiry-to-reservation demo across languages.
