💭 Hard Skills vs Soft Skills — What Really Matters in Tech? When I started my journey in IT, I believed mastering languages, frameworks, and tools was everything. 💻 Java | SQL | Spring Boot — I wanted to learn it all. But as time passed… I realized something powerful 👇 ✅ Hard skills help you get the job. 🤝 Soft skills help you grow in that job. You might be the best coder in the team — but if you can’t 💬 communicate your ideas, can’t 🧠 adapt to feedback, or can’t 🤝 collaborate under pressure — you’ll eventually hit a wall. ⚙️ In today’s world, AI can learn hard skills faster than we can. But it still can’t replace 💡 empathy, 🎨 creativity, 🤝 teamwork, and 🧭 leadership. So yes — 🚀 Learn the tech. ❤️ But also build the human. Because the best engineers aren’t just problem solvers — They’re people connectors. 🌍 💬 What’s your take? Do soft skills matter more than hard skills in today’s AI era? - 🔥 Follow : Chaitanya Kumar Chappidi --- --- --- #SoftSkills #HardSkills #CareerGrowth #TechIndustry #AIRevolution #CommunicationSkills #Leadership #PersonalDevelopment #Teamwork #TechLife #CareerAdvice #EngineerMindset #LifelongLearning #Motivation #WorkCulture #FutureOfWork Chaitanya Kumar Chappidi Vamsi Enduri 10000 Coders

💡Did you know that you can massively reduce the startup time of your Java application – without changing a single line of code? When it comes to performance, many teams rely almost exclusively on classic code optimizations or expensive hardware scaling. But there’s a huge lever hidden in JVM configuration – and it’s often overlooked. Here are 3 features you’re probably not using – but should: 🔹 Ahead-of-Time Class Loading & Linking (JEP 483): Classes are loaded and linked before the actual startup. This saves valuable milliseconds during boot. 🔹 Ahead-of-Time Method Profiling (JEP 515): Uses real-world execution patterns to prepare optimized startup configurations. The result: significantly faster cold-start performance. 🔹 Compact Object Headers (JEP 519): Reduces memory usage per object with more compact header structures – less RAM consumption, more efficient classloading. Especially in the cloud, every second of startup time – and every MB of RAM – matters. These features can help you scale more efficiently and noticeably cut cloud costs. 👉 If you’re wondering whether and how you can enable these features in your project: just drop me a message. I’ll show you how to get the most out of your JVM – without touching your code.

Is Go the new Java for backend engineers in 2025? After 5 years in Java & Spring Boot, I recently spent a few weeks diving deep into Go, and I’m starting to understand the hype. Here’s what stood out to me: • Simplicity — no annotations, no magic. Just clean, readable code. • Built-in concurrency — Goroutines + Channels are ridiculously powerful. • Fast compile times & performance — feels almost unfair. • Smaller binaries = faster deployments = happier DevOps. But here’s the kicker: Companies like Uber, Dropbox, and even parts of Google are rewriting backend services in Go. And now, I’m seeing more Danish/European startups hiring Go developers alongside Java for microservices. I’m not quitting Java (yet), but I’m definitely considering building my next side project in Go. Curious to hear from others: Is Go taking over your team’s backend stack too? #golang #backenddevelopment #softwareengineering #java #springboot #microservices #developers #career #techtrends2025

🚀 I Dockerized My Real-Time Messaging App — QuickChat! Over the weekend, I successfully containerized my personal project QuickChat, a real-time messaging app built with: 🔹 Backend → ASP.NET 8 (SignalR for real-time communication) 🔹 Frontend → Angular (served via Nginx) 🔹 Database → PostgreSQL 16 🔹 Orchestration → Docker & Docker Compose By using Docker, I made the entire setup easy to run, portable, and ready for deployment. 🐳✨ I’ve included: ✅ Dockerfiles for both the API & Angular client ✅ A docker-compose.yml to manage services effortlessly ✅ Services are named QuickChat.API & QuickChat.Client for better clarity Now, with just one command, I can spin up the API, Angular app, and PostgreSQL database together — no more messy local setup! 🔄 If you’re working on .NET + Angular projects, I highly recommend containerizing your app — it makes development & deployment a breeze. 🚀 #Docker #ASPNet #Angular #PostgreSQL #SignalR #QuickChat #DockerCompose #SoftwareDevelopment

I look at hundreds of LinkedIn profiles a day. Here's what 99% of engineers get wrong: 1. Basic headline ❌ "Software Engineer at X Company" Instead, show what you BUILD: ✅ "Backend Engineer building with X Languages | Helped X Company handle 1M+ daily users" 2. Generic "About" section Don't just list technologies. Tell your story: - What problems do you love solving? - Impact of your work (use facts and figures) - Side projects that show initiative - Show off your personality 🦄 3. Experience section Startups want results, not responsibilities. ❌ "Developed features using React" ✅ "Built checkout flow that increased conversions by 32%" 4. Featured section Show off the following: - GitHub repos - Tech blog posts - Open source contributions - Side project demos Startups hire problem solvers, not resume builders. Your profile should prove you're one.

Dear network, Today I’d like to take a brief trip back in time to celebrate the journey of the programming language Java — and why it still matters in modern software development. 🕰️ A bit of history – Java was first publicly released by Sun Microsystems in 1995. – Since then, it has gone through major versions — Java 5 (generics & annotations), Java 8 (lambdas, Stream API), and more recently Java 17 and Java 21 offering long-term support (LTS) and enhanced performance. – Its “write once, run anywhere” promise made Java a cornerstone for enterprise systems, Android apps, and backend infrastructures. 💡 Why Java still matters – Vast ecosystem: libraries, frameworks (Spring, Jakarta EE, etc.), dev tools and a massive community. – Stability & maturity: countless mission-critical systems in banking, social security, industry and retail still run on Java—and evolve with it. – Continuous evolution: despite its 25+ years, Java keeps innovating—modularity, virtual threads, more efficient garbage collection, predictable releases. 🚀 Implications for professionals – Being familiar with modern versions (17, 21) is a major advantage—many teams are migrating or maintaining mature stacks. – Knowing both legacy systems and modern best-practices positions you well across green-field and brown-field projects. – Java experience remains highly valued—especially in enterprise, fintech, insurance, banking sectors—areas where I have myself built software for years. If you’re working with Java—or considering learning it—remember: you’re investing not in something outdated, but in a living, robust, and evolving platform. I’d love to hear: which Java version are you using today? Which new features catch your interest most? Let’s discuss in the comments! #Java #Programming #SoftwareEngineering #TechHistory #EnterpriseIT

𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝘆𝗶𝗻𝗴 𝗙𝗹𝘂𝘁𝘁𝗲𝗿 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗠𝗶𝗴𝗿𝗮𝘁𝗶𝗼𝗻 🚀 Today I decided to update one of my older Flutter projects — a common challenge as Flutter evolves rapidly. After facing tons of Gradle plugin block errors, broken builds, and compatibility issues (AGP, Kotlin, compileSdk, you name it)... I finally found a super simple fix that saved me hours of debugging. 👉 𝗛𝗲𝗿𝗲’𝘀 𝘄𝗵𝗮𝘁 𝘄𝗼𝗿𝗸𝗲𝗱:   1. Backup your /android folder (just in case).   2. Delete the /android folder completely from your project.   3. Run the command: • flutter create . Flutter will recreate a fresh /android folder — now fully compatible with the latest version, plugins block, Gradle, Kotlin, and all! 💥 That’s it. Your project is now ready to build and run using the latest Flutter setup. Hope this saves someone the same headache I had. Let me know if it helps you too! https://lnkd.in/gvXEddjt #Flutter #MobileDevelopment #FlutterTips #Android #Gradle #FlutterDev #CleanCode

🚀 In tech, advice flows faster than code commits. Everyone has an opinion — what stack to use, how to scale, how to write “clean” code. But here’s something we forget: Not all advice is meant to help you. Some is meant to distract, compare, or slow you down. 🎯 Real developers learn to filter — not just warnings in the console, but voices around them. Trust those who build consistently, not those who talk constantly. Because in both life and tech — good intentions matter more than good words. #TechWisdom #DeveloperMindset #ProgrammingThoughts #GrowthInTech #MindsetMatters

🚀 Learning Docker & Docker Compose 🚀 💻 Even recruiters can code! 💻 As a coding newbie, I’ve realized how important it is to use the tools real developers rely on. For those who are new, Hello! I’m Gifta — currently recruiting for Tech & Digital Marketing talents at TEKsystems Tokyo. I started learning to code for fun in my spare time after getting inspired by conversations with developers in my day-to-day work. 🐳  What is Docker? In simple terms, Docker allows your code to run consistently on any computer. To make this possible, we create a Dockerfile, which acts as a blueprint for how your app should run. ⚡Challenges I faced: One major hurdle was database connections. I was used to connecting to my database locally, which caused my Docker image to fail. This experience taught me the importance of decoupling services and designing applications with separate database and service layers. 💡 Beginner concepts I learned from this project: 📌 Using Docker to containerize applications 📌 Writing Dockerfiles and Docker Compose configurations 📌 Managing secrets via environment variables Next steps: ⏭️ Complete unit tests ⏭️ Fix database issues in my test cases ⏭️ Decouple tests so CI/CD pipelines work properly Here's my github repo: https://lnkd.in/gYuYyWVf Would love to hear your feedback or beginner tips! #tech #beginner #dev #java #backend #RESTAPI #docker #dockercompose #dockerfile

Coding won’t make you stand out in AI anymore. Everyone knows Python. Everyone can use TensorFlow. But that’s not what gets you hired in 2025. Here’s what separates top candidates from the rest: ✅ They can explain complex models to non-tech teams ✅ They think critically — not just follow tutorials ✅ They understand ethics, bias, and real-world risks ✅ They know how to deploy models — not just train them Technical skills are the entry ticket. Soft skills are the promotion ticket. 🔧 Yes, learn this: - Python, R, TensorFlow - NLP, Computer Vision - Transformers, GANs - Docker, Kubernetes, Hugging Face 🧠 But don’t skip this: - Communication - Problem solving - Creativity - Ethical thinking AI isn't just maths and code anymore. It's a strategy. It's empathy. It's trust. Credit to: AI Fire on Pinterest _________ If you've ever asked yourself: How Do I Use AI? Follow for the answers you're looking for.
