First up: Sorting Algorithm Visualizer Interactive tool to see how algorithms work in real-time (Bubble, Quick, Merge sort etc.) ✅ Deployed & liveBuilt to learn + teach data structures …mparisonsortingvisualizer.netlify.app #DataStructures #JavaScript #HTML #algorithm

@trikcode Hii dev's 👋

bcrypt vs Argon2 in 2026? bcrypt (2004): ✅ Battle-tested, used by Twitter ❌ Vulnerable to GPU attacks ❌ No memory-hard protection Argon2id (2015): ✅ PHC winner, OWASP recommended ✅ Memory-hard = GPU-resistant ✅ Configurable cost params For new projects? Argon2id wins.

🔐 I spent 3 hours implementing password security for InvoiceFlow. Here's what EVERY developer needs to know about hashing & salting: (Rainbow tables will haunt your dreams) 🧵👇

⚡ JWT vs Sessions Battle! JWT ✅ Stateless = Infinite Scale Sessions ✅ Revoke Instantly = Max Security JWT: No DB lookup, mobile-native Sessions: Logout works, admin bans work Production: JWT (15min) + Refresh Token DB = Best of both! 🏆 #Backend #Auth #SystemDesign

🔐 OAuth 2.0 flows decoded! ✅ AUTH CODE - Web apps (MOST SECURE) ✅ PKCE - SPAs/Mobile ✅ CLIENT CREDS - Server2Server ❌ IMPLICIT - DEAD (token leak risk) OIDC = OAuth + User ID Production rule: Authorization Code + PKCE always! #OAuth2 #Auth #SystemDesign

🚨 IDEMPOTENT HTTP Methods = Network-Resilient APIs! 1 call = 10 calls = SAME RESULT ✅ ✅ GET - Read (safe) ✅ PUT - Replace entirely ✅ DELETE - Gone forever ❌ POST - Creates multiples 😱 ❌ PATCH - Cumulative changes Why? Retries won't break your data!

HTTP Methods are the backbone of every API! 🚀 GET - Read data (Safe ✅ Idempotent ✅) POST - Create resources (Not safe ❌ Not idempotent ❌) PUT - Replace entirely (Idempotent ✅) PATCH - Partial updates DELETE - Remove (Idempotent ✅) Master these 5 = Master REST APIs 💪

HappY new year 🎉

@trikcode That's a great roadmap

Learn to code. Build something small. Ship it. Repeat 100 times. That’s the roadmap.

@Pauline_Cx New one more clean and clear 👌🏻

Improved Feedbask landing page with a clear headline to be more professional. Left: New one Right: Old version

@SaidAitmbarek @Niklas_Sikorra Great product 👍

@Niklas_Sikorra got mine mostly from social media, twitter + many DMs from founders then decided to build + dedicate microlaunch.net to this mission founders launch & go from 0 to 10 sales

How did you get your first 10 customers?

@srishticodes Absolutely right💯, to get off campus you have to build a strong portfolio

People love saying college doesn’t matter. They are liars College still shapes early opportunities. On-campus hiring is simply easier. Fewer applicants, clearer filters, faster decisions. Off-campus is brutal. Tens of thousands competing for a handful of roles. That said, not being from a top college is not a dead end. It just changes the game. If you’re off-campus, stop optimizing for volume and start optimizing for signal. LeetCode alone won’t save you. Use it to build fundamentals, then prove depth. Build real projects, not clones. Pick a niche and go deep. Write, ship, contribute, show work in public. Open source, internships, freelancing, research, startups, anything that creates visible proof. Referrals and networking matter more than ever. This is how hiring actually works. College gives a head start, not a lifetime guarantee. Without it, the path is harder but still very real.

@cinamarina I use MERN stack for building the SaaS

What’s your favorite tech stack?

@deepacodex React and tailwind

Which frontend framework do you enjoy most?

@jonathanbrnd Figuring out how to get the client

What’s the most painful part of building a SaaS?

Invoice generation working! 🎉 Shipped: ✅ Multi-step invoice form ✅ GST calculation (CGST/SGST/IGST) ✅ HSN/SAC code selector ✅ PDF generation with Puppeteer ✅ Professional invoice template Most freelancers don't know HSN codes. Added for common services. Sample

@Niklas_Sikorra Quick GST Invoice generation for freelancers.

Pitch your product in one sentence:

@Prathkum Absolutely right by using vibe coding we quickly build tools for our own use. 💯

Vibe coding has one underrated benefit. You can quickly build your own workflows or tools without waiting on anyone. If you develop such tools, here's a better way to do it:
