The Beginning — When Computers Were Toys
I do not remember exactly how old I was the first time I touched a computer. What I remember: a big CRT monitor, a white CPU tower that had already yellowed, and that distinctive beep sound when you powered it on. It was a retired office computer from my dad, brought home because it was no longer used. I was in 4th grade at the time.
The difference between me and other kids my age: they played games. Counter-Strike, Age of Empires, Need for Speed. Me? I was more curious about why this computer could turn on, why it sometimes hung, and why there was a folder called System32 that people said “do not mess with.”
And yes, I messed with it anyway.
The first time I took that PC apart, I knew nothing. Just a Phillips screwdriver and curiosity. I took everything out one by one: RAM, hard disk, that wide IDE cable, power supply. I disconnected all of it, then tried to put it all back together. The result? The computer would not turn on for three days. Panic. But that is exactly where my first lesson came from: every problem has a solution — as long as you do not panic and are willing to find out.
From Hobby to Habit
Starting middle school, I began to understand that computers were not just toys. I learned to reinstall Windows on my own — using a CD borrowed from an older classmate. Windows XP was still fresh back then. I also met Linux for the first time: Ubuntu 6.06 Dapper Drake, given to me by a friend on a burned CD. The install failed three times because of partitioning. But once it succeeded, it felt like discovering a whole new world.
From that moment I knew: I would never get bored of computers. Because there was always a new problem, always something to figure out.
In high school, I became the unofficial “repair guy” in the neighborhood. Neighbors with slow laptops, friends with virus-infected computers, even teachers whose printers would not turn on — they all came to me. I was not paid (sometimes I got a free lunch), but I got something more valuable: experience solving real problems for real people.
One important lesson from that era: users do not always describe their problem correctly. “My computer is broken” could mean anything — from a power cable not being plugged in to a bad hard disk sector. The skill of translating user complaints into technical diagnosis is actually the most useful thing I still carry with me today.
College and the First Server Crash
Starting college in Information Technology, I thought I would be good at this. Turns out? I felt like zero. My classmates were already coding in Python, Java, building websites with frameworks. All I could do was reinstall Windows and fix printers.
But that turned out to be my strength. In my third semester, there was a group project that required deploying a web application to the campus server. That server was a CentOS 5 VPS, no control panel, just SSH. My classmates — the ones who were good at coding — none of them could access the server. They did not know how to SSH, did not know how to install Apache, confused about why yum update was failing.
I took charge.
My first time handling a production server — and I crashed it.
I mistyped a chmod command. The result: all permissions under /var/www got scrambled. The website could not be accessed, 403 errors everywhere. It was 10 AM at night, with a deadline the next morning. Panic? Of course. But I remembered the lesson from back in elementary school — do not panic, find out.
I SSHed back in, looked up the correct Linux permissions, and fixed the folders one by one. By 2 AM the website was back to normal. The next day the presentation went smoothly, I got an A. But the lesson I carried was bigger than the grade: in the server world, one command can be a disaster, and recovery is a skill more important than deployment.
Entering the Workforce: Helpdesk to NOC
After graduating, my first job: IT helpdesk at a mid-sized company. The work was resetting passwords, fixing laptops, installing software. I lasted two years.
The most memorable ticket? One day at 7 AM — I had just arrived at the office, had not even turned on my own computer yet — the phone rang. On the other end, a panicked voice: “The company website is down! Clients are all calling! It has been 30 minutes!”
I checked. Nothing unusual on the monitoring dashboard. Tried to access the website — timeout. SSH to the server — extremely slow. htop — CPU 100% on all cores. mysqladmin status — Questions: 423981 in the last minute alone.
The root cause: an unindexed SQL query, run by a reporting feature that the developer team had pushed to production the evening before. Nobody had tested in a production-like environment. That one query was doing a full table scan on a table with 2 million rows. (This is similar to the database overload cases I handle often — also read: Troubleshoot High Database Load on MariaDB)
I KILLed that query from MySQL, restarted the service, and the website was back to normal within 15 minutes. But what mattered more: I learned that problems in production rarely come out of nowhere — there is always a trigger, always a recent change.
Becoming a NOC Engineer
From helpdesk, I moved to the NOC team at a hosting company. This is where my career truly took shape.
NOC is different. In helpdesk you deal with people; in NOC you deal with infrastructure. A single server can host hundreds of websites. If that server crashes, hundreds of clients feel the impact. The pressure is far greater, but that is exactly what I loved about it.
One moment I will never forget:
2 AM, alone in the NOC room. The big monitor in front of me suddenly turned all red — dozens of websites down. I checked: the main server had a load average of 200+. SSH was still possible, but slow. dmesg was full of I/O errors. Turns out one of the hard disks in the RAID 10 array was failing. The RAID controller was still trying to rebuild, but the rebuild process itself was causing the server I/O load to skyrocket. (Got a similar problem? Check: How to Fix Apache Slot Full 503 and How to Detect Deleted Files on Linux)
A tough decision: let the rebuild finish (but websites stay slow for hours) or failover to the backup server (but with a risk of losing a few minutes of data).
I chose a third option: throttle the rebuild speed through sysctl, prioritize I/O for the web services first. The rebuild kept running in the background, but websites became responsive again within 20 minutes. By 4 AM the rebuild was done, I sent my report, and went home on my motorcycle thinking: “This is the kind of work I will never walk away from.”
Why I Love Technology
If asked why I still enjoy tinkering with computers from childhood until now, the answer is simple: because technology always has new challenges.
In elementary school, the challenge was getting a computer to turn on after taking it apart. In middle school, installing Linux without a YouTube tutorial. In college, handling my first server crash at work. In the workforce, saving hundreds of websites at 2 AM.
There is one thing I have always believed since the beginning: doing something on a computer is easy — as long as you are willing to learn and not afraid to fail. Including coding. I see friends of mine who are not from IT backgrounds, and they often say “coding is hard.” In my opinion? Coding is just about logic. If you can arrange steps to make a cup of coffee, you can code. You just translate those steps into a language the computer understands.
This mindset is what I carry to this day. When there is a problem, no matter how complex, there is always a solution. It is just a matter of how long and how deep you look.
AI: A Friend, Not an Enemy
In the last few years, the topic I hear most often: “AI is going to replace our jobs.”
Honestly, I disagree — at least not entirely.
I often tell friends, juniors at the office, and even clients I work with: AI does not make us stupid. AI is a life partner that makes our lives easier.
Let me give a concrete example. Before, to debug a weird Nginx error, I would have to open 10 documentation tabs, read Stack Overflow, trial-and-error configs, and sometimes it would take 2 hours to fix. Now? I still do all that, but I can use AI to help analyze log patterns, suggest possible configs, or check whether this error has happened on a previous Nginx version.
AI is like a junior engineer who is super fast at reading documentation. But the decisions are still in our hands. Experience is still irreplaceable. AI accelerates, it does not replace.
Just like Google Search replaced encyclopedias, just like Stack Overflow replaced thick manuals — AI is the next evolution of helpful tools. Not a threat. Not a replacement.
In elementary school, I learned on my own through trial and error. At work, I can use AI to speed up research. The essence is the same: technology is a tool, and it is the human who decides how that tool is used.
Conclusion
The journey from an elementary school kid taking apart PCs to a NOC engineer handling critical servers at 2 AM — it all started with curiosity. Not innate talent, not formal education, but the willingness to keep trying and not be afraid to fail.
If there is one message I want to share, especially for those just starting out: do not wait until you are ready. Just start. Broken? Fix it. Failed? Try again. Because in the world of technology, failure is the best teacher — and a computer, no matter how broken, can always be repaired.
And as for AI? Embrace it. Use it. Make it a friend. Because we are the ones in control — not the machine.
