We Are Carium: Meet Eko Prasetya



For today’s We Are Carium feature, we’re introducing a Software Engineer, Eko Prasetya. Around the office, Eko is known for his fun t-shirts (with their own dedicated Slack channel!), loud mechanical keyboard, and passion for programming. Here’s your opportunity to get to know him.


Fill in the blank: If you really knew me, you’d know_____.

That I’m a nerd and I don’t have a lot of hobbies besides:

  • Writing code

  • Reading books

  • Playing video games

I’m not a big fan of fiction — I usually read technology-related or behavioral economics books. Some of my favorites are “The Mythical Man-Month” by Frederick P. Brooks Jr. and “Predictably Irrational: The Hidden Forces That Shape Our Decisions” by Dr. Dan Ariely,


I used to spend a lot of time playing video games, but with all of my commitments (I still need to sleep!), I barely have time to play anymore. The one I still play occasionally is Dota 2. It’s fun, and each game only lasts about 30–45 minutes, so I don’t have to commit too much time to play.


What is the nerdiest thing you do in your free time?

I’m not sure this is the nerdiest thing, but I write code for fun. Sometimes I work on algorithms to improve my life — I’ve written code to help with scheduling, decide the best team for video games, and manage my financials. The other weekend just for fun, I wrote code to connect Carium’s solution to Alexa!


I also used to compete in programming competitions, like TopCoder and Usaco, and those are probably the most complex ones I’ve solved to date. My kids code too, so in our spare time, we compete with each other.

What makes you proud to work at Carium?


We’re trying to improve the way people manage their health by using technology to be more empowered. Working in a space that has the ability to improve people’s lives, not solely focused on financial gains, is a pretty cool thing — not everyone can say that.


What’s the coolest thing you’re working on right now?

I’m working on the configurable and programmable platform that allows our solution to be tailored to our customer’s needs.

Each one of our customers has different requirements for how they want to approach and communicate with their patients. They need a platform that is relatively quick to deploy and easily customizable.


I’m enjoying working on this project because it’s challenging. It requires me to understand many different aspects and behaviors of our system components so they can be connected together in a way that is simple, extendable, and scalable.


Our system consists of many different components, such as:

  • A messaging system

  • Identity management

  • A scheduler

  • Patient-generated health data

  • Electronic health record data

  • Data analytics

  • And much more

Every one of these components can be tweaked in different ways to directly or indirectly affect how the system interacts with our partners or their patients. A lot of work goes on behind-the-scenes to make sure that a configuration change in one component doesn’t break the others.

Another hard part about working on this project is around the simplicity of the solution. It was quite a revelation for me to see that what we think is easy, doesn’t mean the same thing for other people who use our tools. I can’t count the number of times I had to refactor, tweak, and extend our solutions to make them simpler. Like Greg Weidner, MD FACP says, when you think it’s simple enough, make it ten times simpler.


What motivates you?

I think our solution can make a big difference in the healthcare landscape. If we do this right, we could change people’s lives. And I am excited to be a big contributor on that journey.


What has surprised you most about working at Carium?

Working with a remote team isn’t as scary as I thought. I worked with remote teams at my previous company, but the ratio was about 90:10. At Carium, the ratio is about 50:50, and it works surprisingly well.


What’s the best piece of professional advice you’ve ever received?

To do great work is to love what you do.


What’s your favorite part about your job?

When I see that people use the solution that I’m heavily involved in creating, and hear that they genuinely like and appreciate it — it’s the best feeling in the world.


Who inspires you?

There are many great people out there. But top of my mind, I would say Elon Musk. He isn’t afraid of pushing the boundaries and challenging the status quo. He is also a voracious reader and understands a lot of things well.
