Ðekawɔwɔ — community mutual-support social network for Ghana Volta Region (H0 hackathon build) # Ðekawɔwɔ > "the making of one" in Eʋegbe — community as one body A community mutual-aid platform for the Volta Region of Ghana, engineered to scale from one town to millions on Amazon Aurora DSQL. Connects people who need help with people and organizations who can give it, and offloads non-emergency burden from Ghana's emergency services. **Prototype — not for live emergency use.** Always contact 112 (unified), 191 (police), 192 (fire), or 193 (ambulance) for life-threatening situations. ## Live preview - App (logged-out) - App (signed-in) - Architecture & scale - AI services - Design system ## The vocabulary Intentional, not generic: - **Ask** — request support (not "report" / "incident") - **Give** — offer help (not "alert") - **Wish** — name the support a town lacks; aggregated wishes route real resources - **Drop a Pin** — share location only - **Me** — profile (not "settings") - **Speak** — voice-first ask/give for low-literacy access across 11 languages ## The audience Beta: ~180,000 residents of Ho and surrounding Volta settlements, across 11 languages — Eʋegbe, Avatime, Logba, Tafi, Nyagbo, Sekpele, Siwu, Sélé, Akan, with English and French as bridges. The pattern generalizes to any community. ## Architecture — three databases by access pattern - **Aurora DSQL (primary)** — globally-distributed, strongly-consistent social-graph core: users, connections, matches, follows, trust, wishes, languages. Active-active multi-region, scale-to-zero. `infra/sql/dsql-schema.sql` - **Aurora PostgreSQL + PostGIS** — geospatial engine: drop-a-pin, 8km radius, map, nearest-settlement. `infra/sql/postgis-schema.sql` - **DynamoDB** — write-hot feed, audit log, TTL ephemeral pins; Streams mirror geo-events into PostGIS. `infra/lib/data-stack.ts` Supporting: S3 (media/static/audio), Timestream (Speak-pipeline telemetry).
