The Part of Dashboard Work People Notice First Is Not the Part That Builds Trust
One thing Power BI made much clearer to me is that a dashboard can look polished, interactive, and easy to use while still being built on weak logic underneath. That matters because dashboards are often the part people notice first. They see the charts, the slicers, the interactivity, the clean layout, and the speed at which they can move through the report. A good dashboard can absolutely make analysis easier to explore and understand. But that usefulness depends on somethin

Why Better AI Use Starts With Better Prompting
Before spending money on agents, automation tools, or complex AI workflows, it may be worth fixing something more basic first: the way you prompt. The more I use AI tools like ChatGPT and Gemini, the more I notice the same pattern. Many people already use them every day, but still at the most surface level. They open the tool, type a request, read the answer, and judge the result from there. If the output feels weak, the conclusion often comes quickly: maybe the model is not

The Quiet Counterbalance
On Saturday, 7 March, I volunteered at a briyani distribution event in my neighborhood during Ramadan. The initiative was organized by our RC to support residents during the fasting period.

I spent the first few weeks exploring where my skills could translate and where they could grow. It was uncomfortable not having certainty. I had no commercial proof. No visibility. No roadmap. So instead of waiting to feel ready, I started building. I built this portfolio. I completed targe

Two Weeks. One Question: Did I Actually Learn It?
For the past two weeks, I immersed myself fully in the Google Data Analytics Professional Certificate. I was spending more than 10 hours a day on it, treating it like a full-time commitment. With the help of ChatGPT and Gemini to clarify concepts and challenge my understanding, I completed a programme that typically takes six to eight months within two focused weeks. At the beginning, I started questioning myself. Finishing a course in two weeks is one thing. Actually retaini

The Quiet Struggle Behind This Transition
A Note for Anyone Standing at the Same Starting Point If you’re in the early stages of a transition and finding it more uncomfortable than you expected, you’re not alone.

That can be especially difficult if you’re used to clear milestones or external validation. This piece isn’t meant to offer advice or a roadmap

Where to begin when you know you want to change, but don’t know how A Note for Anyone Standing at the Same Starting Point If you’re considering a career transition and you already have a role in mind, don’t rush. Before worrying about skill gaps, ask whether the role actually suits you. Look beyond job titles. Read reviews, but don’t rely on them blindly. If you can, talk to people in the field.
