Vibe Coding – Linkedin Post

Standard

I just spent 10 USD credit to top up my Anthropic credits and try Claude Code.
And I love it ! 😊
But this post is not about vibe coding using terminal like a cave man.
Let’s appreciate how AI coding make my job redundant err easier …

Stone Age – Once upon a time … Pre AI
You go to stackoverflow, read the most upvoted answer, copy and paste the answer.

Silver Age – Manual AI Coding / ChatGPT
Go to OpenAI ChatGPT / Claude Website and manually key in the chat / prompt and manually copy paste the code generated.

Golden Age – AI / Vibe coding 💸
This is where you spend money to get more money or die bankrupt.
The amount of tokens / credit required can make you broke like how you move to AWS paying NAT Gateways *cough*.

IDE Integration aka choose your hammer / chainsaw
Cursor
Windsurf
VS Code + Copilot
Jetbrains Junie

UI / Frontend / Mockup coding
bolt
lovable

Futuristic Age – Next level ?
Non-technical person or product owner can just type their user story and “prompt” in Jira or Trello task board, the AI will generate the code and create a pull request to be merge to final code branch. All these run in separate VM.

Something like Google Jules ? https://jules.google/

Notes:

Standard Prompt for Code Generation
https://www.reddit.com/r/ChatGPTCoding/comments/1f51y8s/a_collection_of_prompts_for_generating_high/

Anthropic Prompt Library
https://docs.anthropic.com/en/resources/prompt-library/library


My current favourite / cheapest way
Step 1 – Open https://speechnotes.co/dictate/ or if you have money https://wisprflow.ai/
Step 2 – Use my microphone and edit the prompt later like Ironman giving command to Jarvis
Step 3 – Paste to web based “chat”gpt / Gemini / Claude / DeepSeek free versions. Refer Silver Age.
Step 4 – ???
Step 5 – PROFIT


Alternatives
You can just create a heavy, big and long documentations with a bunch of sequence diagram and anything with boxes and arrows that nobody else understand.
That is your prompt.

Outsource to software developer in India or Malaysia

You pay money

You get your app / code

If you vibe code and scold the AI, the AI will just give AI answer.
But with offshoring you can at least interact with human being and blame them.

LOVE LIVE AI CODING ! Woot !

Dah Makan ?

Standard

Startups that delivers healthy food to your doorstep (usually lunch to office or maybe dinner at home).
Consist of 2 parts. FOOD & DELIVERY !
Foodpanda is aiming for food delivery (like DHL, Poslaju but with parcel) because they work with so many restaurants to offer many choices of food but it is very hard to minimize the cost and control the food quality.

Hence, Dah Makan have their own central kitchen.
About the central kitchen, I assume it is located at Lot.27 Jalan 16, Kampung Cheras Baru, 51600 Kuala Lumpur. http://www.jobstreet.com.my/en/companies/823202-farm-to-fork-dah-makan but then something else pop up when I search the same address.

Mangkuk Ayam Catering ! http://mangkukayamcatering.com/?page_id=63

Anyway, their main office is in Mont Kiara.

To conclude, Dah Makan is like Pizza Hut / Dominoes Pizza where they make the food and deliver to the customer.

How it works ?

1 – Customer order food through website (shopify) and mobile app (Android / iOS).
2 – Chef cooks the food from the central kitchen.
3 – Rider(20-30 people ?) deliver from central kitchen to customer.
4 – Customer gets the call from rider and pick up the food.
5 – PROFIT !

Problem ?

Based on my findings from the Play Store reviews

1 – Their order got cancel and the user is only notified by email. (Send sms / push notification instead ?)
2 – Food quality is hit or miss. (Better qc from the head chef ?)
3 – Charged twice.
4 – Somehow on February 2016 the app is not working.

Based on my findings from the Facebook comments

1 – Someone ask about Halal certification. They dont have the cert yet but the chef is muslims.
2 – How to order / what is price / is my area included (Customer’s fault for not going directly to the website but so far their social media exec handle the question well.)

My suggestion.

1 – Have your rider bring extra food especially for lunch order.

Picture this scenario when your colleague ask where to go for lunch (usually this question is very hard to answer):

Staff A – Where do you guys have lunch ? Can I join ?
Staff B – Oh. I ordered my lunch <insert food name here> from DahMakan. You need to order xx time early.
Staff A – (feeling left out).

What if the rider offers them extra food for Staff A to purchase with some extra fee ?

2 – Food suggestion for existing customer.

Rate the food or services. Or push notification by telling them some related food is available next week.
When the food is delivered, ask them for feedback (5 star rating)

3 – Delivery mode.

Assuming rider can carry 6-8 foods, dont be afraid to pair the riders with a Van. At least the rider don’t have to go back to central kitchen where they can just restock their delivery box from the Van. This is a good way to distribute the load among the riders especially when they have many orders that is around 10 KM radius but limited storage space for the riders. Consider the van as mini refrigerator 🙂

Conclusion

So far they have done a good job promoting the services by giving coupons to some company.
Their social media showing the dishes can make people mouth watering.
And lastly, hope they can scale the “traveling salesman problem”
