What I'm looking for

I’m looking for a product leadership role where I can own outcomes end-to-end, use data-driven prioritization, and partner closely with Engineering and Design. I’m especially excited by API-driven commerce and measurable growth in high-growth teams.

I’m a Product Manager with 4+ years of experience leading digital products at high-growth tech companies, including API-based commerce platforms, Internet Booking Engines, and Offer & Order systems. I own the full product lifecycle—from discovery and roadmap definition through execution, launch, and post-go-live growth.

I thrive in cross-functional environments, partnering directly with Engineering, Operations, and Design, and managing direct reports. At FLYR, I defined product strategy for Shopping Cart APIs and led the go-live of Riyadh Air’s native Offer & Order airline capability, while using Claude and Claude Code to streamline technical documentation and PRD/backlog workflows.

I’m also strongly analytical and commercially focused, using client analytics and end-user behavior to drive measurable outcomes—like increasing conversion rate by 1 percentage point at FLYR and improving conversion from 1.0% to 1.55% at Grupo Planeta–Tantanfan. Previously at Johnson & Johnson, I managed a $200K budget and delivered 250% annual revenue growth to $1M through eCommerce strategy and digital product rollouts.
