The problem

Centralised the customer journey and operational data, reduced manual hand-offs and set up a documented AWS foundation.
A WhatsApp-based job platform (Altur), Harambee Youth Accelerator's move from a mobisite to WhatsApp, and eButler's WhatsApp ordering with payments through Flash.
Integrated the installer management system into Multichoice's payment process so installers are paid accurately and on time.

What was built

Led architecture and hands-on engineering for an online booking platform: Python APIs and the AWS deployment architecture, integrated with Paystack, Sage Accounting, Zoho Bigin and Zoho SalesIQ.
