When I started exploring cybersecurity, I thought it was purely about fortifying systems against technical attacks. But the more I learn, the clearer it becomes that securing applications is fundamentally about protecting people: their data, their privacy, their trust.

My passion for this field deepened even more when I came across the news of the SK Telecom USIM leak in South Korea. Seeing how millions of people's sensitive information could be exposed due to security oversights made it painfully clear that behind every breach headline are real individuals whose lives can be disrupted or harmed.

Whether I'm working on a parallel password cracker in C or building socket based chat applications, I always think about how misuse could impact users. Secure design is about anticipating how systems might be exploited and building defenses that protect real lives and reputations. It's also about communicating risks clearly, so that teams and users can make informed decisions.

At the end of the day, cybersecurity isn't just a technical problem. It's a human responsibility.

One of my favorite projects was creating a multithreaded ticket booking system in C. Using pthreads and mutex locks, I had to ensure that multiple users could book seats without collisions or overbookings.

It taught me firsthand how complex concurrency can get. Race conditions and deadlocks aren't just academic concepts, they're real risks that can break trust and compromise data integrity in applications people rely on. This experience deepened my appreciation for designing secure, robust systems that handle concurrency gracefully, something that's just as important in web apps and cloud platforms.

It's small projects like this that give me a practical mindset toward building reliable software in high stakes environments.

As I prepare for a career in cloud and application security, what excites me most is the scale and collaborative nature of the cloud. Unlike traditional environments, securing cloud infrastructure means thinking about multi tenant systems, data in transit across the globe, and managing security as a shared responsibility between provider and customer.

I love that cloud security is never static. It pushes you to stay ahead of evolving threats and to architect solutions that are both scalable and resilient. More than anything, I'm drawn to the idea that by securing cloud ecosystems, I can help protect countless businesses and individuals at once, magnifying the impact of thoughtful, secure design.
