Born in the Andes mountains of Ecuador and now based in London, I'm a Full Stack Developer with 5+ years at Engine AI, where I've grown from Junior Developer to Squad Lead.

Key Strengths

Design mindset

I don't believe in perfect the first time. Iteration and continuos impromements are the bread and butter of my work. I'm also alright when someone asks my opinion on visual design matters and product usability.

Positive & Great communicator

I can put complex technical concepts into bit sized easy to understand pieces. Also, I'm empathetic and a postive person. I like what I do and I bring this energy to my team.

Technical leadership

I'm a good leader. I can create a vision of where we need to go and encourage and support the team to get there together.
