Debugging Beyond Code: Logs, Metrics, and Dependencies

A small mistake that cost me hours of debugging  Recently, I faced an issue in backend code that looked simple at first.  But it took hours to fix because I missed one thing:   Understanding the complete flow before debugging  What I learned:   ✔ Trace the full request flow   ✔ Check logs before jumping into code   ✔ Avoid assumptions  Debugging is not about fixing fast, it’s about understanding deeply.  Have you faced similar situations?  #Java #BackendDevelopment #Debugging #SoftwareEngineering

🐛 Debugging is a Superpower Every Developer Needs Real development is not writing code… It’s fixing what breaks. One thing that helped me a lot: 👉 Don’t panic. Read the error carefully. ✔ Check logs ✔ Reproduce issue ✔ Break problem into smaller parts Most bugs are simple — we just overthink them. Great developers = great debuggers. Agree? 👇 #Debugging #Java #Developers #ProblemSolving

Got hit with a NullPointerException today. I kept checking the logic again and again… Turns out, I forgot to initialize an object before using it. Fix: Proper initialization before calling methods Lesson learned: Always check for null before using objects. Debugging is frustrating but also the best teacher. #Java #Debugging #DeveloperLife

Dependency Injection is not just one thing. It usually shows up in a few common forms: constructor injection, setter injection, and field injection. Each one works a little differently, but the idea behind all of them is the same: write code that is cleaner, easier to manage, and simpler to test. The more you understand these types, the easier it becomes to build applications that are flexible and easier to maintain. #SoftwareEngineering #Java #SpringBoot #DependencyInjection #CleanCode

From confusing loops to clean functional code.🧑💻 If you've ever felt tangled in .map(), .filter(), and .collect(), you aren't alone. The Java Stream API is incredibly powerful, but getting the hang of it takes practice. I just uploaded a comprehensive "Stream API: Zero to Hero" PDF. It covers everything from the absolute basics to advanced operations, designed to get you writing functional Java with confidence. Check out the document below, save it for your next coding session, and share it with a fellow developer who might find it useful! 👇 #saffron#saffron 😆 #Java #Programming #BackendDevelopment #StreamAPI #JavaDev #DeveloperCommunity

Day 42 of consistency 💻🔥 Solved Add Two Numbers using linked lists — a classic problem that really tests understanding of pointers, carry handling, and edge cases. Key takeaways: Handling carry efficiently is crucial Dummy nodes make list problems much cleaner Iterative approach keeps space optimal Not the fastest runtime yet, but improvement is a process — optimizing step by step. Consistency > Perfection. #Day42 #LeetCode #DSA #Java #CodingJourney #ProblemSolving #100DaysOfCode

Sharing a one-page cheat sheet that covers essential Spring Boot concepts for developers. This includes: - Key features & architecture - REST controller example - Dependency Injection (best practices) - Exception handling - Actuator & logging - Profiles & configuration This resource is perfect for quick revision and backend interview preparation. #SpringBoot #Java #BackendDevelopment #JavaDeveloper #Programming #InterviewPreparation

Most backend bugs in production aren't caused by bad code. They arise from assumptions that were never questioned during development. Common assumptions include: - "This API will always return data." - "The network will always be stable." - "No one will hit this endpoint 1000 times a minute." Defensive programming isn't pessimism; it's simply experience wearing a helmet. #BackendDevelopment #SoftwareEngineering #Java #LessonsLearned

I once thought writing code was my job. Then I faced my first production issue. The API was working fine locally. But in production, it started failing randomly. - No syntax error. - No obvious bug. - Just failures. That day I learned: Writing code is easy. Understanding failures is engineering. Now I focus more on: - Logs - Monitoring - Edge cases Because real systems don’t fail in IDEs. They fail in production. #Java #BackendDevelopment #SoftwareEngineering #Production #Learning

Solved: Product of Array Except Self 💡 Key Takeaway: Instead of recalculating product for every index, we can use prefix and suffix products to build the result efficiently. 👉 Approach I followed: - First pass → store left (prefix) product - Second pass → multiply with right (suffix) product - No division used 📊 Time Complexity: O(n) 📦 Space Complexity: O(1) 🔍 What made it interesting: Understanding how left and right contributions combine at each index to avoid redundant calculations. Consistency + clarity is slowly building confidence 💪 #DSA #Java #LeetCode #CodingJourney #BackendDeveloper #SoftwareEngineering
