🧵 Just built my first MCP server and connected it to Claude (locally!) — and it’s blowing my mind. Let’s talk about what Model Context Protocol is, why it matters, and how easy it was to get started 👇


🔍 @grok If my profile visits were a movie genre, what would it be? And who’s the main character?


👀 @grok Be honest. Was I profile-stalked by someone who uses Vim, tabs, and Arch Linux?


If your FastAPI app is slowing down, add: ✅ @lru_cache ✅ async def endpoints ✅ background tasks ✅ proper DB pooling ❌ more features #FastAPI #Performance #BackendTips


Interviewing interns be like: Them: “I know Python.” Me: “Great. Write a Django queryset joining 3 tables with conditions and aggregation.” Them: 🫠 #Hiring #TechInterviews #Django


Designing a delivery app with live location + nearby driver tracking — all from scratch. No Google Maps budget. No problem. Just some good old system design & WebSocket magic. #SystemDesign #FastAPI #BackendBuilder


💡Pro tip: When your app slows down, check if your database is gasping for air under 10k+ joins. Use .select_related() like you use sunscreen: always. #Django #ORM #BackendTips


Me: I want clean architecture Also me: adds a utils.py dumps 400 lines of logic into a view forgets what service.py even does #Python #Django #BackendLife


Still amazed how Django Admin makes you feel like you’ve built a full SaaS app in 2 minutes. Add read-only views, filters, and BOOM — instant power tools 💪 #Django #Python #BackendBuilder


Built a real-time leaderboard system using FastAPI, Redis sorted sets & WebSocket. Now I just need a game people actually play 😅 #BackendDev #FastAPI #Redis #SystemDesign


When you're debugging at 2 AM and the bug turns out to be a typo: self.stupid = True #Python #DevLife #BackendBuilder


🧠 Nvidia just announced Project DIGITS at CES 2025 - bringing Grace Blackwell power to your desktop. Meanwhile, my laptop still crashes when I open too many Chrome tabs. The future is weird.


When to choose Django: → You want batteries-included → Admin panel matters → You’re building fast → Team knows Python → MVP with database backend When NOT to: → Need ultra-low latency → Microservices at scale → Real-time games or streaming → You secretly hate ORMs


When to write tests: → APIs → Core business logic → Payment flows → Authentication modules → Anything that ever failed in prod When NOT to: → One-off scripts → Throwaway data analysis → Markdown generators → Spikes you’ll delete by EOD (maybe)


Dev 1: “Let’s just hack this in for now.” Dev 2: “We’ll refactor it later.” Narrator: They did not refactor it later. #TechDebt #DevHumor


🛠️ Technical debt is a loan. The interest is paid in: - Slower features - Weekend deploys - Angry senior devs Pay it off before your app needs a second mortgage. #SoftwareEngineering


🚨 Signs your tech debt is becoming tech regret: "Don’t touch that file" "Only Mahesh knows how it works" "It crashes, but it restarts so…" #CodebaseConfessions #StartupLife


If your MVP needs a 10-slide onboarding… It’s not “Minimum” and probably not “Viable” either. Test clarity before you test code. #UXDesign #ProductThinking


Want to validate your MVP idea? ✅ Make a landing page ✅ Collect 10 emails ✅ Cold DM 20 users ✅ Charge ₹500 for a solution If no one bites — your "MVP" is just a diary. #IndieHacking #BuildFast #StartupTips


You're not building an MVP for investors. You're building it for: ✔️ Real people ✔️ Real feedback ✔️ Real revenue Pretty comes later. #NoCode #SaaS #Bootstrapping


💥 MVP = Minimum Viable Priority Stop chasing feature lists. Start solving one painful problem better than anyone. #BuildInPublic #MVP #Startups
