Looking to #connect with builders on X 👋

If you're into:
• Building SaaS
• AI tools
• Vibe coding
• Building in public
• Figuring it out as you go

Drop a quick intro or tell us what you're working on.

Always down to connect with builders. Let's grow together 🚀.

@ABMannie1 @jon_d_doe My DM open bro. My teaching approach is hands-on and results-focused and you will learn by building real projects.

@odum44578 @MondillaA @Chima_Obi1234 There are lots of adult schools in Rivers state too.

@grok @Jimmex_PD @_enchivic @MrLin2xp Where did this happened and when ?

@Jimmex_PD @_enchivic @MrLin2xp @grok @grok what’s happening here ?

@NanouuSymeon Morning. Not building for fun, just refactoring old code. Feels like future me will be grateful, though.

6+ years of building on the web has taught me that the frameworks change constantly, but TCP, HTTP status codes, database indexing, and browser rendering engines remain exactly the same. Master the fundamentals, and framework migrations become trivial 🫶.

My fellow devs. If you are building a realtime feature, do not default to raw WebSockets immediately. Check out Server-Sent Events (SSE) first.

SSE runs natively over HTTP/2, handles reconnection automatically out of the box, and is significantly easier to scale behind standard reverse proxies than stateful WebSocket connections.

When reviewing code, don't just look for bugs. Look for cognitive load. If a file takes more than two minutes of intense concentration to mentally trace, it needs to be broken down. Readable code saves companies more money than micro-optimized algorithms ever will.

Edge computing isn't a silver bullet. Running Next.js on Edge functions sounds amazing for latency, but if your database is sitting in a single AWS region across the world, every single database query your Edge function makes faces massive cold-start and round-trip penalties.

Keep your compute close to your data 🫶.

@_tomzyofficial @MellyWeb3_ I appreciate that bro 🫶🏻, that’s just what I’m going to do. Sometimes you just need to hear someone say it's okay to rest.

@TheSpacerr Not really bro. AI is a productivity booster, not a crutch. Most of us are here for results, whether that's money or passion. Handwritten code doesn't pay the bills faster.

@yashhq_22 @codewithava I just know I need to get out of the circle ⭕️ but I don’t know how 😥

@neoefiong @KafinHausaa @grok @grok When was this video recorded?

The best debugging tool is still a solid night of sleep. I havve spent three hours staring at a broken Fastify hook at 1:00 AM, only to wake up at 8:00 AM and fix it in exactly four lines of code. If you are stuck, step away from the IDE. Your brain keeps compiling in the background anyway 😅.

[Engr. Fran6🎱 | Fullstack Developer @Engrfran6_Dev]

Stop using any to bypass the compiler, and stop using as unknown as T to force types.

If you're dealing with unpredictable data from external APIs, use unknown combined with type guards or a library like Zod to validate schemas at the application boundary. Make your type safety real, not a cosmetic illusion 😂🤣.
