The Problem & Challenges
The founder had a proven product concept but lacked the engineering architecture to handle multi-tenant data isolation, usage-based billing tiers, and complex cohort retention reporting.
Our Architectural Solution
Vevtek engineered the entire SaaS foundation in 8 weeks using Next.js App Router, PostgreSQL Row Level Security, Redis caching, and Stripe Billing. We built a fast, intuitive dashboard with cohort retention heatmaps and API usage quotas.
