PyCon & UbuCon Cameroon 2026·Yaoundé, Cameroon·September 2026

Building WhatsApp-Based Health Tech Networks in Low-Connectivity Environments

Delivered live keynote presentation and automated system demonstration of LifeDrop's architecture: asynchronous WhatsApp Cloud API webhooks, idempotent request queues for unreliable 2G connections, and zero-downtime health data alerting. Covers blood donor matching heuristics, MTN MoMo payment integration, and English/French bilingual conversational flows — all built to survive connectivity degradation.

Live Walkthroughs

Recorded demos of production systems. Each shows the real constraint — 2G bandwidth, multilingual UX, clinical workflow — not a polished happy path.
