VOD & Marketplace Platform

The Problem

O Novo Mercado is Brazil's largest digital marketing ecosystem. The engineering team was moving fast but without the infrastructure to move confidently. No shared component system, no experimentation tooling, no reliable way to know if what they shipped actually worked.

My Role

Senior Product Engineer with end-to-end ownership across multiple product squads. I worked closely with the CEO and Product leadership on prioritisation and delivery, and led the XP adoption that changed how the team worked.

What We Built

Vue Component Library

A fully-tested, documented component library (Vitest + Histoire) used across all product squads. It eliminated the "build it again" problem that had been slowing every team down.

• Reduced UI development time by 40% across squads
• Served a platform with 300k+ monthly active users
• Full test coverage with Histoire for visual documentation

Experimentation Infrastructure

Introduced feature flags and Amplitude-driven experimentation to the platform. Something that hadn't existed before.

• Defined the experimentation workflow from zero
• Ran activation, engagement, and monetization funnel experiments
• Directly influenced an 18% uplift in subscription conversion

Platform Ownership

Owned the end-to-end frontend of the VOD platform and freelancer marketplace: subscriptions, content delivery, community flows, and marketplace transactions.

Engineering Approach

Led XP adoption across the engineering team. Not as a mandate, but by demonstrating it worked. Pair programming, test-first development, continuous integration. The team's delivery speed and code quality both improved measurably.

Outcome

18% subscription conversion uplift. 40% reduction in UI development time. A codebase that multiple squads could contribute to confidently. Three years that built the foundation for everything after.
