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.

"Speed isn't about rushing—it's about knowing what to cut."

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."

2020

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."

Building & Scaling Teams

From zero to org scale without losing speed

2022–2023

Fragmented teams 7 squads aligned 40+ engineers

Directed 7 squads, ~40 engineers, 50% of company output

Led Commerce and Payment Experience—the largest engineering group at Primer. Re-architected checkout services to accelerate feature delivery by 80%. Authored engineering principles and progression framework adopted company-wide. Orchestrated a 33% org restructure without impacting delivery timelines.

"Manager-of-managers craft: two-way decisions, remote-first culture."

Bottlenecked org Decentralized leads 50% more throughput

Restructured 20+ engineer org for 50% throughput boost

Joined as Head of Engineering to fix delivery bottlenecks. Decentralized leadership by promoting engineering leads. Shifted to iterative, decision-driven sprints. Implemented DORA metrics and quality KPIs. Result: 50% increase in team throughput and 66% bug reduction in one quarter.

"Sometimes the fix is structure, not headcount."

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."

2022

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."

2007–2010

Manual boilerplate Auto-generated 90% time saved

Code generation tools cut dev time by 90%

Early in career, noticed repetitive boilerplate across projects. Created internal tools that auto-generated standard code patterns. Introduced company-wide unit testing and CI. Started the habit of building tools that multiply team output.

"Tooling mindset—always look for the repeatable problem."

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."
