Extreme Ownership • Check Your Ego

Sean Perkins

I'm a Software Engineer driven by a passion for problem-solving.
With a decade of experience writing code, leading engineering teams, and contributing to impactful open source projects. I thrive on the challenge of making difficult technology feel easy to use.

About me

Greetings! I'm Sean, a passionate software engineer based in Michigan, driven by the ethos of extreme ownership in everything I do. My journey into the world of programming began at the age of 12, when I taught myself Java to create private servers for my favorite online games. Since then, I've embraced an endless pursuit of knowledge and growth.

At 18, I took a leap of faith and founded my consultancy company, where I've had the privilege to collaborate with a diverse range of clients, from local businesses to industry giants like Coinbase. My work spans across various domains, including develoing apps, websites, and design assets, as well as providing engineeering consultancy services.

My background is as diverse as my skill set. I have hands-on experience in frontend development, backend development, dev-ops, mobile/native development, and digital marketing. While I've explored various facts of technology, my current focus lies heavily on frontend technologies.

Let's connect and build better together:
