About Me

Karlo Vrbic - Senior Android Developer

I am a Senior Android Developer with over 8 years of experience building mobile applications that people actually enjoy using. When I am not crafting high-quality Kotlin code, you will find me reading about the latest Android developments, creating presentations for my team, or finding new ways to improve our development processes. I genuinely believe that great software comes from great teams -- and great teams have fun doing what they do.

My superpower? Making complex technical problems approachable and getting everyone excited about solving them together. Some call it enthusiasm. My coworkers call it "that energy before the first coffee that somehow never goes away."

What Drives Me

  • Fun Projects, Serious Results

    Looking for opportunities to build exciting products and improve development processes while keeping things enjoyable for everyone involved.

  • Teaching & Learning

    Passionate about sharing knowledge with coworkers and learning from their fresh ideas and perspectives.

  • People First

    I enjoy connecting with people, exchanging ideas, and using every opportunity to grow professionally -- together.

  • Thoughtful Execution

    I value having the time to think ideas through carefully and execute tasks with the quality they deserve.

Philosophy

Here are some thoughts that guide my actions as a software engineer and Android developer.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand.

— Martin Fowler

Good programmers use their brains, but good guidelines save us having to think out every case.

— Francis Glassborow

Software and cathedrals are much the same; first we build them, then we pray.

— Anonymous

Android development is a challenging but rewarding career. If you are passionate about building great software, then Android development is a great option for you.

— Jake Wharton

*Grrhh* Who wrote this? *looks up git blame* *finds out it was me months ago* It is okay I guess.

— Me (ha ha)

Whether you have a project in mind, want to discuss Android development, or just want to debate whether Jetpack Compose is better than XML layouts (spoiler: it is), I would love to hear from you.
