Cringing at old code is a sign of growth not failure

A junior engineer asked me last week: “How do you know when code is good?” I thought about it for a while. Here’s what I told him. Good code isn’t clever. Clever code is what you write when you want to impress someone in a pull request. Six months later, you can’t read it either. Good code isn’t short. The 3-line solution that took you 2 hours to think of is often worse than the 15-line version that anyone on the team can debug at 2 AM. Good code isn’t perfectly abstracted. Most abstractions I’ve built early in my career were wrong. The ones I built after I understood the problem were right. The difference was waiting. Good code is code that the next person doesn’t curse you for. That’s it. The next person might be a teammate. A junior who joins next year. A future version of you who has forgotten everything. They open the file. They read it. They understand what it does and why. If that happens, you wrote good code. Everything else, including the framework debates, the design pattern arguments, the “this should be a microservice” discussions, is secondary. 14 years in, I’ve stopped being impressed by clever code. I’m impressed by code I can read on a Monday morning before coffee. What’s your one rule for “good code”? #SoftwareEngineering #JavaDeveloper #CleanCode #BackendDevelopment #TechLeadership

Most developers don’t fail because they lack skill. They fail because they optimize for the wrong thing. Early in your career, it’s tempting to chase complexity: 💠 Fancy architectures 💠 Trendy frameworks 💠 “Impressive” code But in real-world software development, the highest value often comes from the opposite: 👉 Simplicity 👉 Clarity 👉 Maintainability A junior dev might spend days building a “perfect” abstraction. A senior dev solves the same problem in hours with code that the whole team understands. Here’s the uncomfortable truth: Your code is not judged by how clever it is. It’s judged by how easily someone else can work with it six months later. Ask yourself before writing code: Can this be simpler? Will my teammate understand this instantly? Am I solving today’s problem or overengineering for a hypothetical future? Great developers don’t just write code. They reduce complexity for everyone around them. 💬 Curious—what’s one time you overengineered something and later regretted it? #SoftwareDevelopment #CleanCode #CodingBestPractices #ProgrammingTips #DeveloperLife #TechLeadership #CodeQuality #SoftwareEngineering #DevCommunity #ProgrammingLife

Learned something new today as a Software Engineer. While working on my projects, I realized: -- Writing code is just one part of the job. -- Understanding why things break is where real learning happens. I spent time debugging an issue and it taught me: -- How systems fail in real scenarios -- Why clean architecture matters -- How small inefficiencies impact performance The biggest takeaway: Every bug is an opportunity to become a better engineer. Still learning. Still building. GitHub: https://lnkd.in/dDwDQVit #SoftwareEngineering #Learning #BackendDeveloper #FullStack #100DaysOfCode

The one skill that separates good devs from great devs 🚀 We all love writing clean code, chasing the perfect architecture, and learning the latest framework. But here’s what I’ve noticed after years of building software: 👉 Reading code > Writing code Great developers spend more time understanding existing systems before adding their own lines. They debug, they refactor carefully, and they leave the codebase better than they found it. 👉 Asking "why" before "how" A junior rushes to implement a solution. A senior questions the requirement first. Is this feature even needed? Does it solve the real problem? 👉 Empathy for the next person That "quick hack" today becomes a 3-hour debugging session for someone else tomorrow. Write comments, write tests, write meaningful commit messages. So my challenge for you this week: Pick one area where you can make life easier for your future self (or your teammate). Refactor one messy function. Add a missing test. Improve the docs. Small actions. Big impact. What’s one habit that has made you a better developer?

Today I tracked every minute of my work as a Software Engineer. Here’s the reality: • 10% → Writing code • 30% → Debugging • 25% → Reading others' code • 20% → Thinking / stuck • 15% → Meetings So yeah… “Coding job” is a myth. It’s mostly: → Thinking → Debugging → Understanding chaos If you're learning to code, don’t just practice coding. Practice: ✔ Debugging ✔ Reading code ✔ Breaking things That’s where real growth is. #SoftwareEngineer #DeveloperLife #CodingReality #DebuggingLife #TechCareers #BuildInPublic #LearnToCode #ProgrammerLife

Have you ever inherited a massive codebase and felt like you're navigating a maze with no clear exit. I know I have, and it's a daunting experience. As developers, we've all been there - staring at lines of code that seem to make sense to no one, not even the person who wrote them. This is where writing clean code comes in - it's not just a nicety, but a necessity when working on large projects. When code is clean, it's easier to understand, maintain, and extend. We can focus on adding new features and fixing bugs, rather than trying to decipher what the code is doing in the first place. This, in turn, saves time and reduces the likelihood of introducing new bugs. I've seen firsthand how clean code can make a huge difference in the overall quality and reliability of a project. So, what does clean code mean to you - is it a set of specific principles, a mindset, or something else entirely? How do you ensure that your code is readable, maintainable, and efficient, especially when working on large and complex projects? #cleancode #softwaredevelopment #codingbestpractices

Senior engineers don't write more code than juniors. They delete more. Question more. And pause longer before touching anything. Here's a habit I picked up the hard way 👇 Early in my career, I'd get a ticket, understand the requirement, and start typing. Fast. Confident. Productive. Shipped in 2 hours. Broke something in 4. Not because the code was wrong. Because I never asked the right questions before writing it. The questions I ask now before touching any backend change: → Who else is consuming this endpoint? → What does the current contract guarantee? → What happens to existing data when this runs? → Which service breaks if this field is missing? → Is this change safe to roll back? Five questions. Maybe 10 minutes. Saves hours of debugging. Sometimes days. The uncomfortable truth about backend systems: Every layer you touch has a shadow layer you can't see. Old clients. Undocumented dependencies. Data that was never supposed to exist but does. The codebase you inherited isn't just what's in the repo. It's every assumption the previous team made and never wrote down. Real system knowledge isn't knowing how to build things. It's knowing what breaks when you do. That only comes from shipping. From breaking prod. From the 11pm Slack message you never want to send again. No shortcut. No course. Just reps. What's the most unexpected thing you've broken in production? 👇 #BackendEngineering #SoftwareDevelopment #SystemDesign #Java #SpringBoot #TechCareers #SoftwareEngineering #BuildInPublic #Programming

Most developers write code that works. The best developers write code that nobody has to explain. The difference isn't talent. It isn't years of experience. It's a handful of habits that quietly separate clean codebases from messy ones. Here are 5 clean code habits that the best engineers treat as non-negotiable: 1. Name variables like you're writing documentation. If you need a comment to explain it, the name is wrong. 2. One function, one job. If you use the word "and" to describe what it does, split it into two functions. 3. Delete commented-out code. That's what Git history is for. Dead code slows every reader down, including the future you. 4. Write error messages for your 1 AM self. Say what happened, what was expected, and where to look. "Something went wrong" helps nobody. 5. Read your own diff before opening a PR. You will catch at least one thing every single time. This habit alone cut my review cycles in half. Which one do you already do? Which one are you starting this week? #CleanCode #CodeReview #SoftwareEngineering #CodingTips #DevLife

The biggest lie in software engineering? That "clean code" is about writing the fewest lines possible. Early in my career, I obsessed over code brevity. I thought if I could condense a 10-line function into a 1-line complex line, I would be a better engineer. I was wrong. Code is read 10x more often than it is written. When we prioritize "clever" code over "clear" code, we create a tax for everyone else on the team (including our future selves). After shipping features, I’ve realized the best code follows these 3 rules: Self-Documenting: If you need a massive comment block to explain what a function does, the function is likely too complex. Predictable: Avoid side effects. A function should do one thing and do it well. Readable for a Junior: If a new joiner can’t understand your logic in under 60 seconds, it’s too clever for its own good. We aren’t paid to write code. We are paid to solve problems and maintain systems that allow the business to grow. Stop optimizing for your ego. Start optimizing for the human who has to debug your code at 2 AM on a Sunday. #SoftwareEngineering #CleanCode #ProgrammingTips #TechCulture #DeveloperLife
