SafiSend - Restaurant Ordering & Payments Platform

Overview

SafiSend is a full-stack restaurant technology platform I founded and led as product and engineering lead. Customers scan a QR code at the table to browse a digital menu, place orders, and pay — including split billing across multiple diners. The system integrates WhatsApp Business API for automated order notifications, M-Pesa for mobile payments, and a real-time admin dashboard for kitchen and order management. Deployed at www.safisend.com.

Challenges & Solutions

Building a reliable, real-time ordering flow across QR code, WhatsApp, and web surfaces simultaneously, while handling split-bill logic, M-Pesa payment callbacks, and live kitchen order state — all with a small team under tight timelines.
