Hi, Your project needs more than a basic chatbot integration — the real challenge is building a low-latency AI calling pipeline that sounds natural during live conversations while handling bookings, FAQs, upselling, and human call transfers smoothly. I’m a final-year Computer Science Engineer with experience in AI integrations, backend systems, automation tools, and ML-based applications. I can help build this using OpenAI/GPT + Twilio/Exotel + ElevenLabs with a scalable Python/Node.js backend. What I understood clearly: • AI inbound/outbound calling • Human-like voice responses • CRM + booking integration • WhatsApp/SMS follow-ups • Call recordings & analytics • Multi-language support • Deployable cloud architecture I can also design customizable prompt/workflow support so businesses can update scripts later without backend changes.

I'll tackle the Elenina AI project by designing a modular workflow that seamlessly integrates AI calling assistants for businesses. The hard part here is defining reliable workflow boundaries, memory, and fallback behavior so the system keeps producing useful outputs over time. My previous work on Jarvis AI - Personal Automation Assistant shows I can orchestrate complex automated workflows and develop AI agents that adapt to changing requirements. This expertise aligns well with the delivery risk in this job. For instance, Jarvis AI built 30+ automated workflows across scraping, system actions, and API-driven automation, ensuring a robust and scalable architecture. To deliver the Elenina AI project, I propose a 4-week execution plan. The first two weeks will focus on designing the workflow, retrieving quality data, and developing a logging mechanism. The next two weeks will be dedicated to testing, refining, and fine-tuning the system. I'll provide a modular workflow code, config structure, logging/fallback handling, and a README document. Before proceeding, I'd like to clarify module boundaries, memory/state expectations, and what the first working loop should cover.

I would build this as a practical MVP first, not an overbuilt call-center platform. The first release should prove one business flow end to end: receive a call, answer FAQs, collect booking details, write the lead or appointment into CRM, and send a WhatsApp/SMS follow-up. Suggested architecture: Twilio, Exotel, or Plivo for telephony, OpenAI/Claude for intent and script logic, ElevenLabs or provider-native voice depending on latency, Node.js or Python backend, PostgreSQL for call/lead/session records, and a small dashboard for calls, transcripts, leads, bookings, and prompt/script configuration. For cost control, I would separate the MVP into clear milestones: 1) inbound voice assistant + FAQ/booking demo, 2) CRM + transcript storage, 3) WhatsApp/SMS follow-up and analytics. Monthly running cost depends on call volume, but for a pilot I would estimate telephony + LLM/voice usage separately so you can see per-call economics before scaling. I can bid INR 25000 for a 7-day MVP pilot focused on one working business vertical, with deployment notes and a clean path to add outbound calls, multilingual scripts, and review collection after the core flow is stable. Relevant work: I built AI caregiving and operations tools with structured workflows, dashboards, automation, and agent-style tool use. This project fits that same pattern: reliable AI workflow + business dashboard + handoff to humans when needed. Transparency: I use AI development tools (Claude Code, Cursor) in my workflow - every architectural decision and line of code is reviewed and tested by me.
