Dialiffy.

Growing teams often struggle with fragmented communications, juggling separate apps for calls, SMS, and analytics. The core tension was the lack of a unified, reliable phone system that could scale effortlessly for remote work without requiring expensive, localized hardware.

Built the full-stack platform end-to-end: React + Next.js + TypeScript on the front, Nest.js + MongoDB on the back, with Telnyx powering business calling, SMS and call routing, and Stripe handling subscription billing. To keep development isolated from production while sharing one cluster, I deployed an Nginx reverse proxy on Ubuntu that routes traffic for both app.dialiffy.com and dev.dialiffy.com, simplifying SSL and port configuration.

Shipped a production-ready cloud communication platform with clean dev/prod isolation. The architecture established a scalable, high-performance foundation ready for real user onboarding.
