✅Calling System| Lovable AI Expert | AI Development | Game Development ✅ Hi, Thank you for considering this opportunity! I bring extensive experience in implementing custom solutions powered by LLMs, conversational AI, and intelligent automation. Recently I have been working on Lovable AI for developing a gaming platform using it, complete with chat-based agent logic, expressive front-ends, and backend integrations. In other project, implemented a fully automated AI agent system for intelligent meeting creation using ElevenLabs Conversational AI and Gemini (via a custom agent brain). The flow integrates voice interaction, natural language processing, location precision, and frontend. Due to NDAs, links aren’t public—but once you open the chat, I’ll share live demos and walkthroughs. Whether you're building an internal assistant, a public-facing voice agent, or an integrated AI productivity tool, I can help bring your vision to life with robust, scalable architecture and a human-like user experience. I would love to connect and explore how we can contribute to your AI initiative. (Note: Budget is flexible — we can finalize it after reviewing the complete scope.) Thanks & Regards, Kajal

Hi, I’m excited about the opportunity to work on your AI outbound cold calling system. With experience in AI-driven voice interactions and automating calling systems, I have previously built similar systems that use speech recognition and NLP to interact naturally with leads. For Phase 1, I can help you develop a solution that automatically reads leads from a Google Spreadsheet, places outbound calls in Singapore English (Singlish), qualifies interest, and books appointments on Google Calendar. The system will leverage Google Cloud Speech-to-Text, Dialogflow, or Rasa for conversational AI, ensuring it can handle objections, interruptions, and natural flow. For scheduling, I will integrate Google Calendar's API to check availability, create events, and send invites. I’ve worked on similar projects before, automating outbound calls and integrating appointment scheduling with Google Calendar and Zoom. I can deliver a reliable solution for Phase 1, ensuring smooth execution from lead input to appointment booking. Thanks, Hercules

Hi, I’ve built and deployed AI outbound cold-calling agents that handle real phone calls, qualify leads, and book meetings automatically. Relevant experience Built outbound AI calling systems for B2B lead qualification and appointment booking Handled objections, interruptions, and natural conversation flow Integrated Google Sheets (lead source), Google Calendar (availability + booking), and Zoom/Meet links Implemented localized voice styles (including accent/tone control) Typical tech stack Telephony: Twilio / Vonage Voice AI: OpenAI / GPT-4o / custom prompt + memory layer TTS / STT: ElevenLabs / Azure / Whisper Backend: Python or Node.js Scheduling: Google Calendar API Lead input & status sync: Google Sheets API Phase 1 approach Read leads row-by-row from Google Sheets Automated outbound calls with Singlish-style conversational tone Script + knowledge-base driven dialogue Objection handling and “call back later” logic with scheduled retries Google Calendar availability check + event creation with meeting link Call status and outcomes written back to the spreadsheet Estimated cost for Phase 1 Final cost depends on call volume assumptions, voice provider choice, and depth of conversation logic. Timeline 2–3 weeks for Phase 1 delivery, testing, and handover Happy to review the detailed Google Doc and refine the estimate once access is granted.

@Microlent

Hello! This is very clearly a real outbound system, not a demo bot, and I appreciate that you’ve scoped this properly as Phase 1. I’ve already built and deployed AI outbound calling agents before, including cold-calling flows that qualify leads, handle interruptions, objections, callbacks, and book meetings automatically. These were outbound systems, not inbound IVRs. In similar projects, I’ve used LLM-driven conversation logic combined with telephony APIs, calendar integrations, and structured state handling so the AI can stay natural while still following business rules. I’m very familiar with call status tracking, retry logic, callback scheduling, and syncing results back to sources like Google Sheets. For Phase 1, I’d focus on making the call flow reliable and human-sounding first. Leads would be read row by row from Google Sheets, calls placed sequentially, and statuses written back immediately. The AI would follow your script and knowledge base, handle objections and interruptions, and switch cleanly between outcomes: not interested, call later, or book meeting. For booking, I’d integrate Google Calendar availability checks to prevent clashes, create the event, and send the invite with your Zoom/Meet/Teams link. Callback logic would be time-based and automated, not manual reminders. I can request access to the detailed document and share my exact stack and prior project summary right away. Best Regards, Jenifer

Hello, I’m excited about the opportunity to help build your AI-powered outbound cold calling system. With experience in AI development, Twilio, and speech synthesis, I’ve previously worked on similar outbound calling agents and can leverage Singlish-style conversational AI to handle objections, interruptions, and natural conversation flow. I’ll integrate the system to read leads from a Google Spreadsheet, automatically place calls, and update the status back. Once a lead agrees to a meeting, I’ll implement appointment booking functionality that integrates with Google Calendar, preventing double bookings and sending invites with meeting links. Best regards, Juan

@hitech10

Hi, I’m interested in learning more about your project. If you allow me access, I can review the requirements properly and provide a more accurate estimation. Can we discuss this further? We will develop this AI outbound cold calling system in a phased, Road-Map-driven manner—starting with lead ingestion, AI calling logic, and appointment booking. By breaking Phase 1 into clear milestones and validating each step early, the system can be delivered efficiently while ensuring natural conversations and reliable scheduling. Development → Deployment Road-Map (Short): Review scripts, Singlish tone requirements, and reference demos Set up lead ingestion from Google Sheets with status updates Implement outbound AI calling flow with objection handling Integrate callback scheduling and retry logic Connect Google Calendar for availability checks and meeting booking End-to-end testing, tuning conversations, and production deployment I’m also interested in a long-term collaboration and future enhancements. If you award me this project, I’d be happy to discuss it further and get started right away. Best regards, Prakash.S

@webmasters486

Hey, I’ve reviewed your project and understand you’re looking to build Phase 1 of an AI-powered outbound cold calling system that automatically calls leads from a Google Sheet, speaks in Singapore English (Singlish style), handles objections naturally, and books Zoom/Teams/Meet appointments in Google Calendar. The system should also handle “call me later” logic with automatic callbacks and proper logging back to the spreadsheet. I can develop a fully functional Phase 1 system using a reliable tech stack (Python/Node.js for backend, Twilio or Vonage for AI calls, Google Calendar API for scheduling, and NLP/AI model fine-tuned for Singlish tone). The solution will read leads row by row, manage conversation flow per your script, book appointments with no double booking, and track callbacks automatically. You’ll receive a tested, ready-to-run system with clear documentation for future phases. Let’s connect so I can provide a precise timeline and cost estimate for Phase 1.

@rosscarter1011

Have you already finalized which telephony API or SIP provider you want to use for the outbound calls, or should I recommend one that best supports Singlish speech synthesis and call handling? Also, will the Google Spreadsheet be updated in real-time by multiple users, or is it exclusively managed by the AI system during Phase 1? The main challenge in Phase 1 is building a robust AI outbound calling engine that reads leads, handles natural conversation with objections, and books appointments without human intervention. My approach is to integrate AI speech and NLP for Singlish, link calls to Google Calendar to prevent double bookings, and implement callback logic while ensuring all call statuses sync reliably with the spreadsheet. I have solid experience building AI outbound calling systems, both cold and warm leads, using Python, Twilio, and Google Workspace APIs. I focus on automating the full lead workflow while maintaining natural conversation flow and seamless appointment scheduling. Let’s connect on chat and drop me a message to start right away.

@JijoThomas2020

Hi! Thank you for the clear Phase 1 requirements. I’d be glad to build your AI outbound cold-calling agent that reads leads from Google Sheets, calls them automatically, speaks in Singapore English (Singlish tone), handles objections/interruptions naturally, and books meetings on Google Calendar with double-booking protection. What I can deliver in Phase 1 Google Sheets lead reader (row-by-row), status updates back to the sheet (called/no answer/interested/not interested/callback scheduled/meeting booked). Outbound calling flow via Twilio, with a script + knowledge base, and robust handling for interruptions and objections. Appointment booking: collect date/time, check Calendar availability, create event, and send invite (including your Zoom/Teams/Meet link). “Call me later” logic: capture preferred callback time, store it, and auto-call back at the scheduled time. Reliable logging + error handling (retry rules, idempotency to avoid duplicates), plus a simple test harness / Postman collection and brief documentation + changelog.
