Senior Project Manager and Solutions Architect. Ten years turning complex telecom and AI programmes into shipped products — on time, inside budget, with the governance to prove it.
White-label AI receptionist sold through channel partners. I owned the architecture, the UI/UX across all three portal tiers, and drove the full-stack build. Real-time telephony bridges Asterisk 23.4.1/PJSIP to ElevenLabs Conversational AI, with Fish Audio and Deepgram as selectable voice engines. Solved the call-transfer identity problem across three competing SIP header strategies, built collision-safe DID allocation that never reuses a retired number, and shipped a CDR pipeline that correctly attributes multi-leg transfers. Enterprise controls throughout: TOTP 2FA, remote session revocation, audit logging, scoped partner API tokens, and soft-delete so historical reporting stays intact.
Production voice agent handling first-line support across restaurants, ISPs, healthcare, e-commerce and order booking. Escalates to a human over SIP REFER when confidence drops.
Moved 30,000+ customers off an end-of-life Cisco BTS10200 in a single 48-hour window. Banks, hospitals and national support centres on the same platform. Dual-DC HA, 6,000 concurrent sessions, CRM-to-CPE automation.
Call-centre card payments without cardholder data ever reaching an agent. Compliance achieved in-house rather than outsourced, which is where the savings come from.
25,000+ numbers managed for a channel partner serving 5,000 end customers. Carrier abstracted away entirely — the partner never sees the upstream.
Direct Routing configured through a UI instead of PowerShell. Enterprises connect their preferred carrier to Teams without needing a telephony specialist in the room.
"Every project has a business outcome hiding inside a technical problem. My job is to find it, name it in language the board understands, and lead the team that solves it — on time, inside budget, without drama."
The SIP identity-header problem nobody warns you about — three competing strategies, one platform limitation, and the fix that held up in production. First in a series on building the AI receptionist platform in public.
