Hi, I'm Karina, a product lead who's curious by default.

I like turning messy problems into things people actually use. Here you'll find what I've built, analysed and written about.

Pull up a chair, and if something sparks an idea, let's talk.

About

Who I am

I've spent 10+ years building digital products at Vivo, Nestlé, BASF and Nubank. The range goes from an app used by 22 million people to Nestlé's first digital wallet, startup pilots in open innovation, and AI-powered internal tools.

How I work

What I enjoy most is structuring and testing business models together with the people who will build and run them: framing a fuzzy problem, running a small pilot with clear success metrics, and scaling what works (or calling it off early). Lately I've been sharpening my data skills and learning more about software architecture, so I can have better conversations with the engineers building alongside me.

Featured Projects

Acuti

In progress
Origin

A personal project born from a recurring doubt: what's the best way to use card points, miles and airline discounts when buying a ticket, given my own situation?

Constraints
  • Compare flights from different locations
  • Sort prices intelligently across ranges of times and places
  • Sort prices intelligently across ranges of financial benefits
  • Filter by personal preferences at the moment of purchase
What it is

A flight search built to get the most out of miles, credit card points and other benefits.

Activities
  • Product design: framed the problem and mapped the real cost of a ticket across 9 factor groups
  • Data strategy: defined three rings of data access, from public market data to personal, consented data
  • MVP roadmap: planned four use-case models, from a single flight to money vs. miles, grounded in three user personas
  • 0-to-1 development of the product

NovaMente

In progress
Origin

Our proposal for the final-stage hackathon of Oracle Next Education (ONE), Oracle's education program.

Constraints
  • Read PDF, Markdown and plain-text files
  • Turn that content into course-style material
  • At least 3 levels
  • At least 2 course formats
  • Mandatory use of Oracle Cloud Infrastructure (OCI)
What it is

A platform where students add their own material and generate personalized courses in the format and level they choose.

Activities
  • Product management: acting as the team's Product Manager
  • Experience and journey definition: journey design and design system production
  • Agent architecture: defined the structure of the agent architecture
  • Embedding agents: detailed the embedding agents and the vector selection by content difficulty level
  • Content assembly: detailed how course content is put together
