Pankaj Joshi

Full-Stack Platform & Telecom Architect · Delhi, India

With 20+ years of engineering experience and 90+ completed Upwork projects, the focus is on building practical systems that connect application engineering with real-time communication infrastructure.

Work spans PBX and VoIP systems, SIP, IVR, WebRTC, AI voice, SaaS applications, APIs, automation and cloud infrastructure.

The approach is deliberately end-to-end: understand the workflow, design the architecture, build the software and telecom layers, integrate external systems, and prepare the solution for production.
