Hi, I understand your need to quickly build a system that captures deals from multiple channels and makes sense of the info using AI. I will set up n8n to connect Outlook, Teams, and Telegram, so all messages go into a structured database. For the AI part, I will use Claude or GPT-4 to automatically pull out key details and store them properly. I will create an auto-match feature to flag relevant requests and offers in Teams alerts. The Retool dashboard will be simple and easy to use, showing all important info on one page. I promise clear communication, good quality work, and support after delivery to help your team work more efficiently. Let's chat and plan a project that grows bigger over time. Regards, Nick.

Hi, The auto-matching engine feeding Teams alerts is the tricky bit here — getting that logic right across three ingestion sources (Outlook OAuth, Teams, Telegram) without false positives takes some care. I've built similar multi-source ingestion pipelines with AI extraction using Node.js and Python, and I'm comfortable with Supabase and prompt engineering for structured record extraction via Claude or GPT-4. My n8n experience is hands-on but not at 2-3 prod deployments yet — worth being straight about that. I'm available full-time this week, Pakistan time (UTC+5), which overlaps your morning if you're EU-based. Budget-wise I'm in your range. Happy to jump on a quick call to see if this is a fit.

@ykarora26

Hi, I read your requirements of an n8n multi-channel deal capture system with AI extraction and it is achievable. I can start immediately with n8n workflow design and AI extraction setup for your deal capture system. I'm a tech-savvy n8n expert and I will set up the ingestion from Outlook shared mailbox and Teams channel, integrate Claude/GPT-4 for structured data extraction, store records in Supabase, build an auto-matching engine with Teams alerts and create a Retool dashboard for your sales team. I can also add a Telegram bot for mobile deal capture and implement OAuth for M365 mailbox access. ✔ I recently delivered similar project with n8n, Supabase, Retool and OpenAI API for a real estate lead system. 1. PropDeal Capture Workflow • Client had manual deal entry from emails and Teams chats with no structured database or matching logic. • I had created an n8n workflow to ingest emails via Outlook OAuth, extract deal fields with GPT-4, store in Supabase and trigger Teams alerts for matched offers with a Retool dashboard view. • Tech Stack Used: n8n, Supabase, Retool, OpenAI API, Outlook OAuth, Teams webhook. ✔ Two Queries: 1. Which AI model do you prefer for extraction? 2. Does the Telegram bot need a public webhook? Note: Please let me know when we can connect and share your Outlook mailbox access and Teams channel details so I can deliver the MVP within 7 days. Warm regards, Yogesh

@joomextensions

Hi, I've reviewed your project carefully — this is exactly the kind of production-grade n8n automation I specialize in. Here's how I'd approach your MVP: ✅ n8n ingestion layer: Connect Outlook shared mailbox (M365 OAuth2), Teams channel webhook, and Telegram bot as trigger nodes ✅ AI extraction: Use Claude or GPT-4 via HTTP/API nodes to parse deal details → output structured JSON (counterparty, request type, offer terms, quantities, dates) ✅ Supabase: Design schema for counterparties, requests, and offers tables; insert/upsert records automatically ✅ Auto-matching engine: n8n logic node compares open requests vs offers by commodity/price/volume → triggers Teams alert when match found ✅ Retool dashboard: Single screen showing live deal feed with filters, match status, and quick-action buttons Closest project: Built a multi-source lead capture system (email + WhatsApp + web form) feeding into Airtable with GPT-4 extraction and Slack alerts — deployed in production for 3 months. Availability: Full-time this week, can start today Timezone: IST (UTC+5:30) — overlap with EU/UK hours Can share n8n workflow screenshots or a quick Loom on request. Let's build this. Regards Harsh Thoriya

@C0RETECHIES

Hello, I understand you're looking to build an operational MVP that captures deal flow from multiple channels. The system will use n8n to ingest messages from an Outlook shared mailbox, a specific Teams channel, and a Telegram bot. Each message will then be processed by an AI model (Claude/GPT-4) to extract and structure key information—like counterparties, items, and pricing—into a Supabase database. A separate workflow will then run a matching engine against these records, pushing actionable alerts to a Teams channel for your staff, with a Retool screen providing the master view. Technical approach: - n8n as the central workflow engine with dedicated triggers for Outlook (M365 API), Teams, and Telegram. - AI node (GPT-4/Claude) configured for reliable JSON output to structure the extracted data. - Supabase nodes within n8n to write the structured records to their respective tables. - A secondary n8n workflow, triggered by database events or a schedule, to run the matching logic. - Retool connected directly to the Supabase instance for a simple, real-time data display. Core modules: - Multi-Channel Ingestion & Authentication - AI Extraction & Structuring Layer - Centralized Record Management (Supabase) - Automated Matching & Teams Alerting - Single-Screen Retool Dashboard Relevant systems: Our "AI-Driven Sales Call Automation System" followed a nearly identical pattern: ingest unstructured data (call transcripts), use AI for classification, update a central datastore (Google Sheets), and trigger automated follow-ups (emails/calendar invites). I can provide n8n workflow screenshots for this. I can deliver this MVP within your 7-day timeline. My fixed price quote is $2,800. I'm available to start immediately this week and am based in IST (GMT+5:30). Regards, Rohit

@Herculesz

Hi I can build this MVP with n8n ingestion from Outlook shared mailbox, Teams channel, and Telegram bot, then use Claude/GPT-4 extraction to normalize messages into structured Supabase records. The main technical challenge is making messy sales/purchasing messages reliably become clean counterparties, requests, and offers while keeping matching alerts accurate enough for your team to trust. I have experience with n8n production workflows, Microsoft 365 OAuth, Outlook/Teams integrations, Telegram Bot API, Supabase, AI extraction pipelines, Retool dashboards, and automated matching logic. I would structure the system with clear n8n triggers, validation steps, deduplication, Supabase tables, match-scoring rules, and Teams alerts when a request and offer line up. The Retool dashboard would stay focused on one operational screen for reviewing records, match status, and recent alerts without unnecessary complexity. Thanks, Hercules
