Multi-Country Network

Self-service reseller dashboard that enabled 50 independent resellers to onboard and manage customers — the primary growth engine.
Multi-Level Affiliate Marketing
Built a multi-level affiliate system enabling resellers to recruit sub-resellers, track referrals, and earn commissions across multiple tiers automatically.

Architecture
How it was built
RadShim was built as a multi-tenant platform with a NestJS + GraphQL backend, Next.js frontend, and self-managed infrastructure across 100+ servers. A single codebase powered all brands through multi-tenant architecture. Every component — from database schema to deployment pipeline — was designed, built, and operated by one technical founder.
