ChocoDelivery

Real-time delivery, AI recommendations, autonomous support — for a single-city chocolatier scaling fast.

Started as a 15-day digital menu. Evolved into a production delivery platform with order tracking, driver assignment, fleet management, an AI recommendation engine, and an autonomous support chatbot handling real customer tickets.

01

From menu to operating system

The original scope: display a menu and save an order. The actual product today: a real-time geo-aware logistics system with live driver tracking, route assignment, and fleet-level KPIs — powered by PostgreSQL + PostGIS and Redis for hot state.

02

Personalized recommendations

An AI recommendation engine surfaces product suggestions from each user's behavior and order history. No third-party SaaS, no tracking pixels — the signal lives in the same database as the orders.

03

Autonomous customer support

A chatbot agent diagnoses order issues, reports real-time status, and handles the long tail of repetitive support tickets. Human agents only see escalations that actually need a human.

04

Observable production

Prometheus + Grafana dashboards for order latency, delivery SLA, and agent resolution rate. Every user-visible failure has a named metric behind it.
