No payment product 3 weeks to launch >1000% revenue growth

Rauva Pay: Concept to production in 3 weeks

The business needed a payment product to unlock revenue—yesterday. Regulatory approval was uncertain, competitors were moving. I assembled a tiger team, cut scope to essentials, and we shipped Rauva Pay in 3 weeks. Regulatory approval took another 3 months, but we were ready. The result: 50%+ cohort adoption and >1000% early revenue growth.

1 month 2 days 15x faster

Third-party onboarding cut from 1 month to 2 days

Payment processors needed extensive back-and-forth to integrate with Primer—documentation gaps, manual configurations, endless support tickets. Built developer-focused APIs, self-serve tooling, and clear integration guides. Partners could now go live in 2 days instead of a month.

"Developer experience is a business multiplier."

Weekly releases Daily deploys 90% faster

From weekly releases to daily deployments

Releases were ceremonial—scheduled, feared, often delayed. Engineers spent more time coordinating than coding. Implemented automated CI/CD pipelines, testing gates, and deployment tooling. Within months, we moved to daily feature deployments. Engineers shipped with confidence.

"Fix the release process and everything downstream improves."

Removing Friction

Eliminating blockers that slow teams and customers down

Fragmented logins Single sign-on 50% fewer tickets

Unified login cut support tickets by 50%

Customers had different credentials across Farfetch properties. Login issues were the #1 support driver. Launched unified Farfetch Login—one account, everywhere. Support tickets dropped 50%. Customer retention improved. Engineering stopped firefighting auth bugs.

"Sometimes the biggest win is removing a problem entirely."

Tangled codebase Modular architecture 80% faster delivery

Checkout re-architecture: 80% faster feature delivery

The checkout codebase had accumulated years of complexity. Every feature took longer than it should. Led a re-architecture across 7 squads. New modular structure, clear boundaries, better abstractions. Feature delivery accelerated 80%. Engineers could reason about the system again.

"Technical debt isn't theoretical—it shows up in delivery speed."

Inconsistent quality Measured quality 66% fewer bugs

DORA metrics drove 66% bug reduction

Quality was inconsistent. Bugs escaped to production, eroding trust. Introduced DORA metrics and quality KPIs—test coverage, story-point accuracy, lead time. Made quality visible. Within one quarter, bugs dropped 66%. Predictability improved. The team took ownership.

"You can't improve what you don't measure."

Rule-based detection AI-first detection $300K+ saved

AI-first fraud detection: $300K+ customer savings

Led the Fraud vertical—~80% of Inscribe's ARR. Shifted to AI-first detection, improving model accuracy by 5%. The improvement wasn't just technical—it enabled customer wins with Ramp, Bluevine, Airbase. Customers reported $300K+ in fraud savings. Closed a major financial institution deal.

"Technical improvements only matter if customers feel them."

Blind to failures Full visibility 7.5% auth uplift

Payment telemetry: 7.5% auth uplift + 20% cost reduction

Merchants couldn't see why payments failed. Built payment telemetry that exposed authorization patterns, failure reasons, and optimization opportunities. Merchants saw 7.5% uplift in authorization rates and 20% reduction in payment costs. Data turned into dollars.

"Observability isn't overhead—it's a revenue lever."
