Project Concept
DriveThruAI is an autonomous, speech-driven ordering assistant designed to fully automate the drive-through experience at restaurants. Customers speak naturally, the system understands their order using real-time speech-to-text, responds using natural TTS voices (powered by ElevenLabs), intelligently upsells items, retrieves live menus via secure webhook updates, processes payments, and personalizes the interaction for returning customers. The entire experience is managed by a custom-built agent FSM (Finite State Machine) designed for reliability, clarity, and real-world deployability.

Raghavendra Manchikatla Team Lead RSVP Approved
Founder at Gharlo
Designed the overall architecture connecting Bolt UI, FastAPI backend, n8n pipeline, Postgres DB, and ElevenLabs TTS.
Implemented core backend services including:
/kiosk/v1/interact conversational agent endpoint
Upsell rule engine
ElevenLabs integration backend for voice generation
Order processing and QR payment module
Developed the Python Kiosk Agent with offline-first support (SQLite outbox + sync).
Coordinated team integration, debugging, and end-to-end system orchestration using Docker Compose.
Ensured project meets all hackathon judging criteria: agentic flow, voice integration, tool-use automation, reproducibility, and real-world deployment readiness.
Tools Used: FastAPI, SQLAlchemy,Supabase,Python Kiosk Agent, ElevenLabs API, Code Generator, Bolt Coordination.

Alle Nikhil RSVP Approved
Data Analyst at Gharlo
built the kiosk UI in Bolt, implementing the conversational interface and order flow screens.
Integrated ElevenLabs TTS into the kiosk to play natural voice responses.
Designed user interactions such as "agent speaking" animations, order confirmation screens, and QR payment view.
Helped configure frontend API calls to backend endpoints (/config, /interact, /order).
Worked with the team to test end-to-end flows including menu updates pushed from n8n.
Tools Used: Bolt Frontend Builder, ElevenLabs TTS API, React (Bolt-generated), Axios, QR rendering.
