@nini_webdev Make sure to optimize your queries before adding cache :)

@rioserenity_ My last name.

@sharm42453 Mentor.

@nini_webdev TypeScript without doubt.

[Francisco Luna 🌙 @LunaEngineers]

@J_Bhargva You can do so!

What tech stack would you want to use there? I believe Next.js or Astro with Markdown will be great for the MVP.

[Francisco Luna 🌙 @LunaEngineers]

@skpnky Quit that job.

Quit the people that were draining you.

Trust your intuition and instincts, not fancy words or promises from others.

Focus on your own skills and the things no one can revoke from you.

@Lyracutevibes It's been good. Maybe I learned lessons I should've learned at 40 or much later, but I'm grateful for the wisdom and for being able to learn from every situation.

[Francisco Luna 🌙 @LunaEngineers]

@iamkayjr There you have your fourth like :)

Sending you lots of luck with your journey on X!!

[Francisco Luna 🌙 @LunaEngineers]

@sharm42453 Narcissism, no doubt.

Look for things like "you're my perfect relationship" or silly games where both parties are drained.

[Francisco Luna 🌙 @LunaEngineers]

@tiya_decodes Can communicate tech to non-technical people and can understand distributed systems.

[Francisco Luna 🌙 @LunaEngineers]

@J_Bhargva Congratulations!!! Keep it up

@surajitsingh_ Chrome is based.

[Francisco Luna 🌙 @LunaEngineers]

@surajitsingh_ I feel comfortable on Windows, although Linux is also great.

@dcoolisek Congratulations! We can connect :)

@nini_webdev Music composition and instruments, lol.

Tried chess and several other things, and I was only good at music 🤣

RAG Tip:

If your ingestion pipeline and data are trash, don't expect good results.

Focus on ingesting your data well and nailing the embeddings.

Garbage in, garbage out.

[Francisco Luna 🌙 @LunaEngineers]

A few lessons learned while building a professional ingestion pipeline in August 2026:

- Prefer snapshots (zlib) over API calls for consistency and to save costs.

- The AI is for interpretation and embeddings, not calculations.

- Keep things simple.

@KomalWCode Communication.

Without it the work you do while debugging and documenting is not going to stand out.

[Francisco Luna 🌙 @LunaEngineers]

@nini_webdev It depends on your budget and how complex the application you're deploying is.

I'd use with DigitalOcean or Railway before starting with AWS to save money.
