IndiaWhat I'm looking for
I've delivered production VoIP and AI systems for clients in Switzerland, Germany, and India, including Asterisk/Kamailio PBX platforms, real-time voice AI call pipelines, and document-search portals with conversational voice interfaces.
At TELUS Digital, I maintained enterprise telephony infrastructure and resolved SIP, ISUP, and trunking issues through call tracing and packet analysis. I build across Python, FastAPI, React, cloud infrastructure, LLM pipelines, and DevOps, and I also contribute open-source projects spanning ML, CRM automation, multi-tenant PBX, and self-hosted developer platforms.
