About me

Sungjin Shin

Cloud Strategy Architect in Okestro

I have accumulated diverse experience over 14 years across two companies, working in development, operations, audits, and management. My roles have spanned ERP, MES, project management, Kubernetes, and AI. While these experiences were invaluable to my career, I sought to redefine my professional identity and decided to take on a new challenge as a Cloud Architect. I dedicated my personal time to thorough preparation, and as a result, in February 2025, I was able to embark on a new journey as a Cloud Strategy Architect at Okestro, the leading cloud vendor in South Korea.

How was this possible with only on-premise development experience and no prior cloud-related career? The answer lies in my determination and effort to transition into cloud architecture. During my preparation, I actively participated in the boot camp led by the renowned AWS Principal SA Rajdeep Saha, consistently promoted myself on LinkedIn, and obtained SAA-C03 and CKA certifications. Additionally, my past experience as an author, having published a book in 2019, played a significant role in strengthening my profile.

However, personal effort alone is not enough. To succeed, I had to demonstrate to hiring companies that I was the right fit for a Cloud Architect role. Cloud architecture requires deep expertise, and transitioning into the field without prior experience is extremely challenging. Without strong self-motivation and a strategic approach, overcoming these barriers would have been nearly impossible.
