Welcome to the "dungeon" known as the data center. I remember my first day reporting to the data center operations team three years ago. Even though I was a 10-year veteran of construction and commissioning who had seen it all, I have to confess... I was intimidated. (Laughs) "Is this the same HVAC I used to know?" "If I make a mistake here, will it make the national news?" That feeling of your heart racing with half-excitement and half-anxiety—you’re probably feeling it right now, aren't you? Once I actually got into it, I realized the skills I learned while breathing in dust at plant sites didn't just disappear. However, this thing called a "data center" definitely has a different personality than a typical building; it is much more prickly and sensitive. Working as a Lead Engineer, whenever I saw juniors falling into a state of "mental breakdown" with the exact same expression I once had, I would see my own reflection from three years ago. "Man, I had to learn the hard way by banging my head against the wall, but I want to teach these guys so it hurts a little less for them." This lecture was created with that single thought in mind. I’ve already gone ahead, experienced the trial and error you'll face, and even put together a complete "incorrect answer note" for you. I have packed in all the know-how from my 17-year engineering career—mixed with my blood, sweat, and refrigerant. So, please feel free to dig in, tear it apart, and savor every bit of it. If you ever think, "What on earth does this mean?" while studying, don't hesitate to ask on the bulletin board or via email. I will come to answer you faster than a UPS (Uninterruptible Power Supply) and with more energy than an emergency generator. Now, shall we get started?

The real story of an AI-native company run by GolbinHacker, the 1st place winner of Kakao AI TOP 100 and author of the bestseller "The Best Prompt Engineering Lecture."

I thought I had seen it all after weathering the sandstorms of Middle Eastern construction sites and experiencing all sorts of hardships, but the moment I broke into the coldest sweat while working as a lead at an Equinix data center was when a "fire protection" issue erupted. Typically, operations teams revolve around two main pillars: electrical and mechanical. As a result, fire protection is always a blind spot. It is common for everyone to feel suffocated by fire safety issues whenever the Ministry of Science and ICT inspections or ISO certification seasons roll around. Since there are no internal experts, people end up relying on PMs or expensive consulting firms. This is where I gained a painful insight as an 18-year veteran engineer: "Those who build can never fully understand the perspective of those who operate." Even after spending a fortune on consulting, the advice often felt disconnected from the reality on the ground, and sometimes the answers were simply wrong. Out of sheer frustration, I decided to break through it myself. After obtaining licenses for both electrical and mechanical fire protection engineering, I sat down at the table with PMs and designers. Only then did I start to see the real picture. I realized that in this industry, there are very few people who truly understand data center fire protection within the context of "operations." Even now, having moved to a different company, the situation remains the same. In the end, there is no one who will prioritize or protect our operations team first. We only see as much as we know, and things only become as safe as the level of persistence we apply in our demands. That is why I created this course. Regardless of whether you hold a license or not, I have packed this course with "practical fire protection knowledge" that data center operations teams can use as an immediate weapon on-site, distilled from my 18 years of experience. If you get stuck while studying or encounter something in the field that doesn't make sense, don't struggle alone—feel free to ask anytime. Like an emergency engine pump that runs flawlessly even during a power outage, I will be standing by to answer you immediately.

"Have you ever seen months of overtime vanish with a single piece of paper?" Do you know what I felt most poignantly while managing five overseas EPC projects? It is the **'terror of understanding procedures.'** The interesting thing about the EPC world is that while every site is different, they are strangely similar, like a parallel theory. If you slip up in this game of procedural wits, you’re in big trouble. It is the fate of EPC that even a single task requires breaking through countless approval lines and gateways; if you fail to grasp this, the results of months of pouring your soul into your work can go down the drain overnight. 💡 'Real' experience built while being hammered by the Middle East's Big Three Fortunately, whether it was luck or grit, I managed to save and successfully complete every major overseas project I was assigned. Thanks to that, I am confident I can tell more vivid stories than anyone else on 'how to run an overseas EPC project well without failing.' In particular, you can't ignore the 18 years of experience I gained while being pushed to my limits by the three most notoriously difficult Middle Eastern clients (KOC, ADNOC, ARAMCO). I will extract and share only the most essential, life-saving insights on how these demanding clients pressure procedures and operate their systems. 🚀 For your 'life with evenings' To be honest, I created this lecture because I felt so bitter about the glorious 'trial and error' of my younger days. I truly hope my colleagues and junior engineers never have to experience the terrible mistakes I made—hitting rock bottom on-site day and night, falling into a mental breakdown because I knew nothing. I sincerely hope this survival guide becomes a cheat code that moves your clock-out time forward by even just one hour and reduces unfair overtime. 🛠️ 5-minute standby Q&A support If you find yourself thinking, "What on earth does this mean?" or if there is anything you don't understand while taking the course, please do not hesitate to reach out via the bulletin board or email.

🚨 "Automatic control? Oh, that headache-inducing stuff?" If that was your reaction, come on in! Does the mere mention of "automatic control" give you a throbbing headache? Don't worry, that's perfectly normal! LOL. To be honest, I was the same way. Casting my mind back 17 years to my rookie days when I didn't know the first thing about automatic control... I suddenly landed a job at a foreign company dealing with factory automation systems. My naive fantasy that "the company isn't a school, so seniors will kindly spoon-feed me everything" was shattered into pieces. Expecting a 'kind mentor' from seniors whose souls were being drained by a daily deluge of work was a luxury. In the end, I had to learn the hard way by digging into thick manuals on my own, grasping concepts one by one through blood, sweat, and tears. The result of enduring and grinding through it all? I grew into a seasoned 18-year veteran engineer, leading HVAC construction and commissioning for major overseas projects like Kuwait Oil Company, Abu Dhabi National Oil Company, and Saudi Aramco. ✌️ 💡 Take the shortcut with the know-how I gained from my struggles! I poured everything into this course for juniors and seniors who, like me, are full of passion to grow but feel lost on where and how to start. I'll be honest. I won't lie and say, "Take this one course and you'll be an automatic control master tomorrow!" However, I am confident that once you finish this course, you will have a more solid and clear foundation than anyone else regarding "Ah, so this is what automatic control is!" and "This is how all the gears mesh together!" 🌐 Regardless of your major, automatic control is now a 'must-have survival item'! AI, IoT, autonomous driving, smart factories... the world is changing so fast these days, right? We've reached an era where it's hard to work properly without an understanding of automatic control. For electrical engineers, monitoring systems like EPMS and SCADA are basic setups! Mechanical engineers have also become inseparable from control systems like BMS and FMS. Data center engineers? They have to handle systems with dizzying names like EPMS, BMS, DCIM, and DCOS. While we can't perfectly dissect these complex-looking systems from 1 to 100, I will use my 18 years of experience to explain the **'core functions' and 'basic structures'** they must possess in a way that is far more intuitive and easy to grasp than anyone else. ⚡️ On standby 24/7! Questions are always welcome. If you find yourself tilting your head in confusion or thinking, "What on earth does this mean?" while taking the course, don't suffer alone! Feel free to knock on my door anytime via the bulletin board or my email. Just like an Uninterruptible Power Supply (UPS) that provides power without stopping for a single second, I'll always be waiting here to support you. 🔋 I hope my fierce survival story becomes a powerful weapon in your level-up journey. Now, shall we go smash through the headache of automatic control together? Let's go! 💖
