Pricing Domain Modernization for Dynamic Experimentation
"Kate's work was impressive. She demonstrated that a good PM on a technical App Modernization project can provide massive value. Her ability to focus and prioritize helped our team meet the OKRs in just 3 weeks. The client feedback was stellar and I strongly believe Kate's contributions played a big role. Thank you, Kate!"
The impact
Pricing modernized from fragile legacy logic to a centralized, reusable platform service. Modular experimentation enabled across Buy and Sell flows. Dynamic pricing strategies for high-demand events unblocked. Living roadmap and architecture artifacts left behind to sustain the work.
I led discovery and delivery for StubHub’s pricing architecture modernization, transforming siloed, legacy pricing logic into a flexible platform that could support real-time experimentation, modular APIs, and future dynamic pricing strategies. The engagement moved fast - leadership needed to see ROI early - and we delivered.
How we got there
StubHub’s pricing tools were a liability. Logic was scattered across internal tools, ops workflows, and legacy code with limited documentation and no clear ownership. Engineers couldn’t iterate confidently. Product teams couldn’t trust the data. Pricing strategy leaned on instinct because the systems couldn’t support anything better.
I started with event storming and service mapping sessions to get cross-functional alignment on what the current state actually was. The POET tool, a core piece of the pricing infrastructure, was identified as both a critical dependency and a source of brittleness, so I prioritized its refactor as the early modernization win that would unlock downstream work without breaking existing buyer and seller experiences.
From there, I worked with engineering, pricing strategy, and platform teams to define a clean domain model and future-state APIs for both Buy and Sell flows. We mapped synchronous and asynchronous state change messaging across critical domains, integrated with Optimizely and pricing aggregators to enable experimentation, and built modular pricing object models that made A/B testing and price guidance actually tractable. I delivered a multi-stream roadmap with milestones, metrics, and modernization impact so the team could continue the work after the engagement ended.
What this built
- A centralized pricing platform the engineering team could actually iterate on. Reusable APIs across Sell Flow, Buy Flow, and Auto Pricing logic replaced the legacy patchwork with something owned and maintainable.
- Real-time experimentation capability. Dynamic pricing for high-demand events, A/B testing across flows, and integrated metrics dashboards became possible for the first time.
- A living roadmap and architecture foundation. The strategy model, Miro diagrams, and phased migration plan gave StubHub a clear path forward after the engagement, not just a snapshot of work done.
