📌 Preparing for SDE-2? Here’s What Actually Matters Transitioning from SDE-1 to SDE-2 isn’t just about more experience — it’s about depth, ownership, and architectural thinking. Here’s a simple roadmap to help you grow into the next level: --- 1️⃣ Strong DSA Foundation Not competitive-coding level — but strong enough to: Write optimised solutions Explain trade-offs Identify patterns quickly Focus: Arrays, Hashing, Two Pointers, Sliding Window, Trees, Graphs, DP, Heaps, Tries. --- 2️⃣ System Design (HLD) SDE-2 is expected to: Design scalable, fault-tolerant systems Evaluate trade-offs (DB choice, caching, partitioning, consistency) Communicate architecture clearly Start with: URL Shortener, Rate Limiter, Chat App, Feed System, Notification Service. --- 3️⃣ Low-Level Design (LLD) Be comfortable with: OOP principles Class diagrams API design Designing modules cleanly Goal: Think in components, not just functions. --- 4️⃣ Ownership & Execution SDE-2 manages complexity: Own features end-to-end Break down tasks Improve code quality Write scalable modules It’s less about “finishing tasks” and more about driving outcomes. --- 5️⃣ Behavioural Excellence This is where many fail. Work on: Clear communication Conflict handling Handling ambiguity Showing leadership even without title --- 6️⃣ Build Depth in One Area Pick one: Backend | Mobile | Distributed Systems | Databases | Networking and go deep enough to mentor others. --- Final Thought SDE-2 isn’t a promotion — it’s a mindset shift. You’re not just writing code anymore. You’re designing systems, unblocking others, and thinking long-term. #SDE2 #softwareengineering #programming #systemdesign #dsa #career #techcareers

🧑‍💻 What I’m Geeking Out About as a Developer on July 27, 2025 It’s been a whirlwind this month across frameworks, AI, languages, and cloud platforms. Here’s a breakdown of the most impactful updates I think developers should know: 🚀 Ecosystem Highlights 🔷 Google & Firebase (I/O Connect India / Cloud Next) Firebase Studio now offers AI-optimized templates, seamless backend integration, and better collaboration using Gemini AI Agent tools — built to rapidly prototype AI-powered apps with familiar frameworks. Google emphasized agentic AI workflows (Agentspace, Agent2Agent) and Gemini expansion during recent live events — supercharging real-world usage across cloud, media, and business agents. 🔧 Microsoft & Visual Studio 18 A major overhaul is underway for Visual Studio 18, with deep AI integrations aiming to compete with tools like Amazon’s Kiro and Cursor. Internal testing is already in progress. 📱 Framework & Language Evolution React 19 (Codename "React Forget") introduces automatic memoization and true agnostic bundler support. Python 3.13 brings 25–40% speed gains via the Faster CPython effort, plus evolving static typing and experimental multi-core support. Rust sees broad adoption in systems, embedded, and Wasm; Swift 6 now targets Windows and Linux; Go 1.23 enhances generics and WebAssembly support; and promoters like Zig and Mojo are gaining traction for high-performance computing. 🐍 Python Tooling VS Code’s Palantir extension now features environment conflict visualization, letting you trace dependency issues visually instead of parsing error logs — a huge win for stability in Python projects. 💬 Meta & Kotlin / Company Stack Kotlin 2.0 debuted at KotlinConf with new cross-platform compiler (K2), improved lambda efficiency, and the open-source AI agent framework “Koog” that runs within the JVM. Stack Overflow’s roadmap confirmed upcoming feature expansions: ai-powered search via stackoverflow.ai, richer threaded comments, and community-sourced coding challenges. 🔎 What’s Catching Your Interest? Have you tried building a prototype with Firebase Studio + Gemini templates? Which language update—Rust, Go, Kotlin—are you exploring this summer? Or were you more intrigued by Visual Studio 18’s AI-powered future? Let’s chat — I’d love to hear what’s making a difference for you in the dev stack right now. 👇 https://lnkd.in/dbn2XPpK https://lnkd.in/dyuyfBHW #DeveloperDaily #AIinDev #FrameworkUpdates #ProgrammingLanguages #CloudAI #SoftwareEngineering #Kotlin #Python #Go #Rust #StackOverflowAI

Brutally Hard Tree DSA Question asked in an Apple SWE Interview (₹60 LPA CTC) 🚀 Apple SWE Interview DSA Video Solution Link - https://lnkd.in/dvFe2Q7a This wasn’t a template-based question. It required deep tree intuition, structured DFS reasoning, and optimization thinking under pressure. What stood out: • Strong fundamentals > memorized patterns • Tree problems are evolving in interviews • Implementation clarity matters more than fancy tricks In the video, I break down: – How to approach the problem – Key insights that unlock the solution – Clean optimized implementation – Complexity analysis If you're preparing for Apple / FAANG / top product companies — this will give you clarity on the level expected. #Apple #SWE #FAANG #DSA #CodingInterview #TreeAlgorithms #TechCareers #SoftwareEngineering #InterviewPreparation #CompetitiveProgramming 🚀

🚨 When a CORS Error Wasn’t Really a CORS Error A few months ago, we faced a strange production issue. Frontend users were getting: “Access to fetch from origin blocked by CORS policy” The funny part? CORS was already registered in Program.cs. Everything looked fine. My colleagues were scratching their heads ,the configuration was correct, so why was it failing in production? I took a deep breath and thought: “Okay… maybe it’s not really CORS.” Just to be sure, I tested the backend production API in Postman. Boom 💥 it was down. The problem wasn’t CORS at all. The server simply wasn’t running after deployment, but the browser’s error message made it look like a CORS issue. 💡 Lesson learned: Not every CORS error in the console is actually a CORS problem. Sometimes, the browser just reports what it sees but the root cause can be network issues, server downtime, or deployment failures. Since then, whenever I see a CORS error, I: ✅ Test the API directly (Postman / curl) ✅ Check server health and logs ✅ Only then debug the CORS configuration Sometimes, the scariest-looking bugs just need a calm head and a systematic check. Have you ever chased the wrong problem because the error message was misleading? #CORS #WebDevelopment #SoftwareEngineering #BackendDevelopment #FrontendDevelopment #API #Debugging #ProgrammingTips #WebAPI #DeveloperLife

System Design is not something you only worry about once you hit Senior SDE, trust me 👇 Because in reality, System Design shows up much earlier, and it’s a very imp. filter for any roles beyond SDE-2/3. That’s why I’m sharing this “System Design Made Easy” doc 📄 Big thanks to Bosscoder Academy for curating this structured guide! 🙌 📌 Check their programs here → bcalinks.com/Rr38sAy Here’s what you’ll find inside the doc: → Core concepts explained step by step (scalability, caching, load balancing, CAP theorem, databases) → Breakdowns of real-world system architectures → A 60-day roadmap designed to fit alongside a full-time job If you’re a mid-to-senior SDE prepping for your next role, this doc can save you weeks of scattered prep and give you a roadmap that actually works. And if you’re serious about growing into Sr. SDE roles at top PBCs, Bosscoder Academy’s EVOLVE program for SDEs with 6+ YOE is built exactly for this. They’ve already helped 2200+ engineers crack top PBC roles, maybe you’re next? #systemdesign #seniorsde #techinterviews #growth #jobswitch #collab
