Pega Decisioning Architect | Real-time Next-Best-Action on Pega CDH (Verizon) | CPDC, CSSA, CSA
Barking, United Kingdom
Worldwide
I build Pega CDH decisioning that picks the right offer in under a second, at 5,000 transactions a second. Seven years of it at Verizon.
Based in London, with full UK right to work. No sponsorship needed.
If you run Next-Best-Action on Pega Customer Decision Hub, the strategy is rarely the hard part. Keeping decisions fast, safe and explainable once real traffic hits is.
That's where I've spent my career:
- Re-engineered Verizon's decisioning API orchestration from 4 seconds to under 1, holding 5,000 TPS through Black Friday and device launches
- Designed real-time budget and anti-gaming controls on high-value rewards, against an estimated $5B revenue risk from offer abuse
- Built voice-intent decisioning that joins Pega CDH, Google Contact Center AI and an in-house GenAI model, so agents get a personalised offer mid-call
- Retention flows that cut customer churn by 15%
I own the APIs end to end. Design, release, production support, and mentoring the engineers and vendor teams around them.
Certified CSA, CSSA and CPDC, plus the Google AI Professional Certificate.
