  • Designed, built and run a multi-business customer chat platform: each business gets its own AI agent on WhatsApp and website chat, and its team can step in on any conversation from a shared inbox.
  • Connected businesses to the official WhatsApp Business Platform (Cloud API) as a Meta-verified Business Tech Provider: number onboarding, message templates, broadcasts and webhooks.
  • Built the backend in Python (FastAPI, SQLAlchemy, Alembic) on MariaDB/MySQL and the dashboards in Next.js and TypeScript; per-business agents run as n8n workflows with RAG on Pinecone and OpenRouter models.
  • Added AI-to-human handover, team availability, phone push alerts, analytics, an embeddable website chat widget and an admin console for running every business.
  • Built billing end to end: automatic invoices, PDF downloads and online payment by mobile money and card through Selcom, with receipts by email.
  • Secured and operated it: data kept separate per business, rate limits, emailed sign-in codes, signed webhooks, encrypted backups every 6 hours, and CI/CD on GitHub Actions testing against MariaDB, MySQL and SQLite before each deploy.
