Meet the Team: Interview with Jaume, Developer

The Blockchain team is growing very quickly which is why we love these profiles.

Catalan-born Jaume is a developer whose focus has been primarily on our web wallet. His travel portfolio reminds me of another developer on the team, Sjors, who has also visited and lived in his fair share of places around the world. Currently Jaume is settled in Ottawa, Canada.

Alyson: What do you enjoy about Ottawa so far?

Jaume: Well, I’ve only been here for a month and a half. It has been warmer than I expected. I really enjoy cycling, and there are a lots of bike paths near the river. There are also so many squirrels. So far so good, but people told me horror stories about winter: -40 degrees Celsius, I might freeze solid.

**A: What do you like most about your role as a developer?**

J: I like solving problems. You know how some people like to solve sudokus for fun? For me, solving sudokus is boring because it’s a mechanical task. When you’re a computer engineer you are constantly playing a game of abstraction, trying to find general solutions for concrete problems.

The most exciting and unknown part is the creative and artistic side of the job. When you have to solve a problem, you usually don’t have a predetermined way to do it. This means you have to be creative to find a solution. There can also be different valid solutions for the same problem. This is where the aesthetic part comes in –  some solutions are prettier than others. Maybe because they are shorter, easier to understand, they use a really smart idea, or you simply like it more. Why do you think song A is better than song B?

In mathematics, computer science, or engineering in general, creativity and aesthetics are probably one of the most important and amazing parts. And I love it!

A: More specifically, what about your work on our team?

J: I have been refactoring a lot of code for the wallet. You can see some of my work by signing up for an alpha invite here. My main goal is to improve the codebase and write things that are easier to understand and test, which means shorter code if possible. Finally, the point is to achieve the maximum correctness possible.

A program should be almost a theorem. I write a function that I claim it does something, so I have to prove or be really sure that my function computes what I claim.

**A: So, what intrigues you about bitcoin?**

J: More than intrigued, I am excited. I think it is amazing to contribute to something with a high chance of producing  an economical and social revolution all around the world. If you think the technological changes of the past 20 years have been amazing, wait another 20 years. They are going to be unimaginable and bitcoin is going to be a big part of this.

A: How do you think developers currently working in the bitcoin space can encourage other developers to get involved in bitcoin?

J: I think bitcoin is sexy. Maybe lots of developers have not discovered it so much, but once you read about it and understand it, it’s like a mind trap. This industry is growing really fast and it is only a matter of time until more developers get involved.

**A:  If you could give a piece of advice to all bitcoin developers, what would it be?**

J: Focus on correctness over anything else. No shortcuts, no hacks.

**A: I think a major reason those of us understand the value and benefit to bitcoin is because at some point we began to question what brings value to something, and what causes inflation. **

**Why do you think there has been such a misunderstanding of what bitcoin is?

J: I think the biggest problem is how people understand money. Most people don’t really think about how money works. They consider the concept of inflation and printing money to be normal, and they don’t think to question it.

I asked Jaume if there was a particular world issue that he’s passionate about. He told me this question made him feel like a Miss World Contestant, so I decided to ask him this:

A: Imagine you’re on stage as a contestant in the Miss World competition, what would your special talent be?

J: I love skiing backwards! I learned to ski really young, when I was around 3 years old. I mean, I am not into pro-jumping, like a crazy dude… I don’t want to die yet. But I can ski backwards pretty well.

**A: As far as animals go, you said you most identify with birds, because you enjoy the freedom flying would give you. As a nomad bird, what items would you carry with you at all times?**

J: I think I only need one, my laptop. But maybe I would add my camera as a second item. When I travel I like to bring my camera, and take my time to get a good shot!

Jaume is still deliberating his plan for competing in Miss World – follow him on Twitter for occasional updates.
