Just wrapped up a full RFM customer segmentation project ๐
Took a genuinely messy retail dataset (missing IDs, inconsistent dates, dirty prices) through Excel cleaning โ SQL analysis โ Tableau dashboards.
Biggest surprise: one customer with 88 orders (highest frequecy) didn't even crack the top 100 by spend (frequency โ value).

And while you were reading this list, another data tool was probably released. ๐
If your plan is to learn every tool that works with data before you can call yourself a Data Engineer, you will never become one.
The list is endless.
A Data Engineer is defined by the ability to solve data engineering problems:
Design a data system.
Move data reliably.
Transform and model it.
Test its quality.
Deploy the pipeline.
Monitor it.
Make the data available for use.
You donโt need to know every tool.
You need strong foundations, practical experience and the ability to learn the right tool when the work demands it.
Tools will continue to change.
The trade remains.
Donโt wait until you know everything before you start calling yourself a Data Engineer. You will never know everything.
Even if I didnโt want to support President Tinubuโs administration before, what the Nigeria Police did tonight would make me support him fully.
The Nigeria Police called me tonight to ask about the issue that occurred this afternoon between me and their men on the road.
After he spoke with me on the phone, they released my car.
Wahalaitalai! ๐ I know my age, and I can tell you as a matter of fact that this has never happened to me before.
This is the kind of accountability and intervention we need.
I can tell you one thing: Nigeria will be great again! ๐ณ๐ฌ
This is what we need!!
@PoliceNG_CRU KUDOS TO YOUR TEAM
YOU ARE DOING A GREAT JOB
That's not true. If there will be other God on earth, it gonna be women. The way God created them is so unique, he created them in his own image more then how he created us.
So they got used because of what God gave them. That's why as a lady, the best thing you can do to yourself is to cover up
@rajatjain1107 I'll make my hands dirty with SQL this new week. I created an interactive dashboard in excel, one of the best dashboard I ever create using excel, I get to learn new things. I'm gonna use the same dataset to practice SDL this new week.
