Lion Reach

Multi-channel marketing platform for an online gaming operator, prototype to production in five weeks

From an early prototype with 71 tests to the production system with 1,040 tests, in five weeks.

Private client work: no customer data is shown; the engineering details are mine to share.

Architecture

  • Architecture: campaigns, journey engine and inbox on a Node.js core with a consent ledger

What it is

The in-house outreach platform of a US-facing online gaming operator: SMS, voice and email campaigns with WhatsApp support, a journey engine with a visual canvas, a two-way inbox and AI personas. I took over an early prototype (71 tests) and made it the production system.

Highlights

  • 1,040 passing tests; zero-downtime deploys through systemd socket activation
  • Hash-chained consent ledger, TCPA quiet hours per recipient time zone, STOP handling
  • Role-based access by department, two-factor login (TOTP), SSRF guards; hardened after two security audits
