I’ve been quietly observing the story of a boy named Ryu Kintaro, and I feel it’s time I spoke from the heart. In a world where social media rewards controversy more than compassion, I find it both amazing and heartbreaking to see how a 9-year-old boy pursuing business and personal growth can become a magnet…
(and what this means for us in Indonesia) I’ve been thinking a lot about this lately… maybe too much. Despite all the good that technology brings, I can’t help but feel that social media, for all its promise, has quietly become one of the greatest threats to our collective growth. Not because of what it…
Years ago at Bippo, we needed a solid web developer, someone ready to dive into Java, Spring Framework, and Apache Wicket. One candidate stood out… but not for the usual reasons. – He was a J2ME developer, skilled in mobile Java for feature phones. – No experience in HTML, CSS, JavaScript. None. – By resume…
When you’re building backend services with NestJS, one of the first things you’ll notice is this: 🧱 Out of the box, there’s no observability, just logs. But logs alone don’t tell you how your service behaves under load, or why requests are slowing down. So here’s what we did: 🔍 What I was trying to…

Serverless seemed ideal: – Pay-per-use – Easy to get…
The context: I’ve worked with both REST and GraphQL, especially with Hasura for auto-generating GraphQL APIs. The decision often comes up when architecting new APIs for SaaS products or internal platforms. Choosing the right one affects team velocity, frontend/backend boundaries, and observability. Options considered: 🔹 Traditional REST API (NestJS + OpenAPI) 🔹 GraphQL (custom backend…
When I was a tech lead at Telkom Indonesia, I had to make several infrastructure decisions for our analytics stack. We started by storing our initial analytics data in Elasticsearch, which worked well at first. We had great Kibana dashboards up and running. But when it came to more complex data manipulation, we hit a…
Some time ago, I’ve been experimenting with building a chatbot powered by Llama 3, LangChain, and vector databases. Initially Qdrant, later switched to Chroma. Why RAG? I wanted to test if I could build a helpful assistant from a specific knowledge base. In this case, content from Heni Ardiana’s beautiful travel website, Pesona Matahari 🌻…
I recently set up Google Analytics and PostHog for a project, both for web and product analytics. 🔍 What I was trying to answer: How are users actually using our product, week to week? 🛠️ Tools used: Google Analytics + PostHog 🤯 What I found: While GA is great for general traffic insights (and scales…
