This was how he ended the call with me, a few days ago. I don’t need you, I can do vibe-code the system myself. Goodbye! This is not something new for me. I have lived through various types of clients and prospects. Many are decent, some are rude, some are unreasonably so. But c’mon, there is no necessity for you to share with me your thought processes, and neither am I interested in your retort. There are no winners and losers here. I’m a service provider and you are a client. That’s all.

Why Everyone’s Suddenly Talking About “JSON” Okay, I’ll be honest. Back when I first heard about JSON (pronounced “Jay-sawn” like some tech guy who drinks oat milk and wears Crocs), I thought it was a fancy new café in Tiong Bahru. Turns out it wasn’t on the menu, but it was everywhere else — powering websites, apps, APIs, CRMs, chatbots, and yes, even your food delivery app that somehow forgets your chilli sauce. Now, as a software and mobile app developer based in Singapore for more than two decades (yes, since before Grab was even a thing), I’ve seen tech buzzwords come and go — but JSON stuck. And if you’re a startup founder, a no-code builder, or just someone who keeps hearing “JSON” and nods politely while secretly Googling it in another tab — this one’s for you.

Wondering whether to choose Salesforce or build a custom CRM? We compare costs, features, pros and cons, and long-term ROI to help you pick the best CRM solution for your business.

Imagine this: A potential customer visits your website, likes what they see, and wants to ask a simple question before making a purchase. But instead of an easy contact option, they find an email form (ugh, who even checks emails anymore?) or a phone number they have to manually dial (too much effort!). So, they leave. Forever. Ouch.

A Singaporean Developer’s Perspective. If you’ve ever wondered how apps, websites, or systems magically talk to each other, congratulations — you’ve just stumbled into the nerdy world of APIs. Don’t worry, I’m here to hold your hand through this digital jungle. Before you start imagining APIs as a secret society of programmers in black hoodies, let me clear that up. No, it’s not like Hogwarts for geeks (though that would be cool). API stands for Application Programming Interface. Still confused? Thought so. Let me break it down.

Not the One You Eat! If you’ve ever browsed the web and wondered, “Why does this site seem to know me better than my best friend?” — you’ve just met cookies. Not the chocolate chip variety (though those are delicious too), but the tiny data packets that live in your browser. Let’s unwrap this digital mystery, shall we?

To add a WhatsApp button to your website, you can use the WhatsApp API link, which allows users to start a chat with a specified phone number directly from your site. Here's a step-by-step guide.
