Twilio Voice & SMS Developer | RingCentral, IVR, A2P 10DLC

I help businesses fix what's broken in their Twilio Voice, SMS, and A2P 10DLC systems, reducing dropped calls, carrier rejections, and blocked SMS traffic. I specialize in A2P 10DLC brand and campaign registration, including rejection fixes other providers couldn't resolve, alongside Twilio Voice architecture, IVR systems, call routing, and SIP trunking. My work focuses on diagnosing the actual root cause before touching anything, so the fix holds and the system stays reliable. One client had an SMS campaign stuck for weeks over a non compliant 10DLC setup. I found the exact gap, corrected it, and had them approved and delivering again within days, including resolving a 30007 carrier violation error. Another client's outbound dialer was dropping one in five calls, a week after I rebuilt the Twilio Voice architecture, every call was landing clean.
