Hi, I'm Vasco.

I'm a software engineer with a love for building digital products.

I specialize in full-stack web development using Ruby on Rails and React. I also have experience with mobile development, having shipped five iOS apps.

Cadouu

Group Gifting Platform

Work

Co-Founder & CTO, lead developer

Cadouu makes organizing group gifts painless. It allows friends and family to come together and celebrate a special occasion by pooling their money and giving one big gift in the name of everyone. Besides the monetary contribution, people can also leave a personal video message that only the receiver will see.

We raised an angel financing round and went through one of the top European accelerators. Unfortunately, the products did not get enough traction, but I learned a lot about product development and technical leadership.

FitnessRace

Multiplayer Fitness Mobile Game

Fitness Race combines a step counter and mobile 3D game with the goal of incentivizing people to live a more active lifestyle.

The game takes the steps you walk in real life and converts them into in-game steps that you use to race your friends in cartoonish levels based on exotic locations such as New York, Hawaii or Berlin. If you are falling behind, why not try some power-ups such as a Cupcake Trap or a Spaghetti Tornado.
