I came across an interesting thought today: Deleting 1 million rows from a table can take seconds (or more)… But dropping that same table? Almost instant. As developers, we use these operations all the time—but the difference in performance is huge. Why does this happen? #programming #interviewQuestion #coding #softwareEngineering
Table deletion vs deletion in SQL performance

My code is working. That’s the problem. I don’t know why it works. I don’t know how it works. But it works. So now I’ve entered survival mode: • Don’t touch it • Don’t refactor it • Don’t even look at it too much Because last time I got confident… I created bugs that didn’t even exist before. At this point, the code and I have an understanding: I leave it alone. It keeps working.

Do not try this at home 😂 Making changes across 242 files before committing is far too much for anyone to review effectively. Keep your changes small and focused on a single feature. AI can help you write code but that's no excuse to abuse it. #SoftwareEngineering #CleanCode #CodeReview #Programming #Developers #TechLeadership #AIinTech #CodingBestPractices #DevLife #SoftwareDevelopment #EngineeringCulture #TechCareers

DRY (Don’t Repeat Yourself) — simple idea, big impact. It just means: 👉 Don’t write the same logic again and again. Why we use it? Because repeating code creates problems 👇 Fixing one bug = fixing it in multiple places Changes take more time Code becomes messy and hard to manage With DRY: ✔ Write logic once ✔ Reuse it everywhere ✔ Easier to maintain and update Simple rule: If you’re copying the same code again… it’s probably time to make it reusable. #CleanCode #DRY #SoftwareEngineering #Coding #Developers #Programming #CodeQuality

"You are the master of your fate." Until you deploy on Friday, forget one environment variable, and suddenly your destiny is in the hands of the logs. Every developer learns this eventually: You can't control every bug, every requirement change, or every "quick fix" request. But you can control: - Your code quality - Your learning - Your response under pressure Real mastery in tech isn't about avoiding problems. It's about debugging them without debugging yourself. #DevT #SoftwareEngineering #Programming #Coding #Developers #TechLife #CareerGrowth

Interviewer Question 👇 You start typing a username on Gmail — and instantly the UI says: “Username already taken.” But here’s the catch: There are hundreds of millions (even billions) of users globally. 👉 How does the system check availability in milliseconds? 👉 How is it able to respond so fast without scanning massive datasets every time? #softwareEngineering #development #coding #interviewQuestion #programming

May be you keep fighting AI, or you find a way to master, direct and own it. Whichever you choose, I can guarantee that, that will be the determent of your tech success within the next 5 years. The industry will keep moving forward, one offended expert at a time.

Yeah, I remember when I first started using AI in my coding workflow, I actually felt a bit shy about it. I even tried to hide it from people because it felt like using it somehow meant I wasn’t a “real” engineer. Fast forward to today, and my perspective has completely changed. I now feel confident using it as part of my development process. It’s helped me deliver tasks faster and often with better quality. Instead of taking away from my skills, it’s become a tool that enhances how I work.

What is a variable? A variable is a way to store data in a program so you can use it later. Think of it like a labeled container that holds a value. This value can be a number, text, or other types of data. Instead of repeating the same value everywhere, you store it in a variable and reuse it when needed. Variables also allow your program to change and respond to different situations. For example, you can store a user’s name, update a score in a game, or keep track of calculations. They make your code more flexible, organized, and easier to manage. #webdeveloper #tech #coding #programming

A simple rule to keep in mind while building a new application - Rule of three C's : Reduce the 3 C's - Complexity, Coupling, and Cost. Complexity = hard to read, hard to change. Coupling = one change breaks everything else. Cost = infra, maintenance, and onboarding that adds up fast. All three shrink with the same trick - build only what you need, keep it simple, and draw clear boundaries. #SoftwareDevelopment #SoftwareEngineering #WebDevelopment #SystemDesign #Programming #CleanCode #BuildInPublic #DevTips #Tech #Coding

What are loops and when do I use them? Loops are used in programming to repeat a block of code multiple times without writing it again. They are helpful when you need to perform the same task repeatedly, such as going through a list of items or running a calculation several times. Instead of writing the same code many times, a loop handles it automatically until a condition is met. Common types include for loops and while loops. You use loops when working with arrays, counting, or processing data step by step. They make your code shorter, more efficient, and easier to manage. #webdeveloper #tech #coding #programming
