Boost: outbound voice AI conversion optimization

Reworked an outbound voice AI sales setup and proved the lift with measurement. Instrumented 546,000 conversations in BigQuery, built an audio validator that found 67% of reported successful transfers were voicemails, migrated dialing platforms, built a queue dialer and caller-ID bridge, and ran Bayesian A/B tests on scripts.

• Validated real-human transfer rate up 5.5x (0.43% to 2.37%), comparing January 1-14 with April 1-9 under the same validation standard.
• Combined transfer and callback engagement up 2.4x (1.77% to 4.26%).
• First 10 days of April 2026: 39 transfers produced 10 confirmed sales, matched to won opportunities in the CRM.

"Cameron did excellent work on our voice AI project. He reworked our existing setup for noticeably better performance, built out live reporting so we could track stats in real time, and added quality control to distinguish real human transfers from voicemails. He also migrated us to a new dialing system and built a second bot to work around limitations we were hitting on the original platform. We ended up doubling our transfer rate ahead of target.

On top of the technical side, Cameron is genuinely easy to work with. He communicates clearly, gives helpful context around any issue that comes up, responds quickly, and stays solutions-focused."

Upwork client review, 5.0

Before voice AI, I managed $12.5M+ in Meta ad spend across client accounts and led editors, creators and global teams. I know how a campaign gets built, what the numbers have to look like, and when ads are the wrong answer for a business.
