About
Hi, I'm Tanzim Ahmed
I'm a data analyst based in Kolkata, and CommandDeck is my studio for one thing: helping businesses actually see their numbers. I work with Python, Power BI, Excel and MySQL daily, and I build every project like it's going on my GitHub — because it usually is.
No agencies, no handoffs, no junior outsourcing. You talk directly to the person building your dashboard, from the first call to final delivery.

FAQ
Questions clients usually ask
My data is a mess — can you still build a dashboard?
Yes — that's the most common starting point. Data cleaning is included in every dashboard package. Messy Excel files, duplicates, inconsistent formats: I sort all of it before building.
Do I need a Power BI licence?
For viewing shared Power BI dashboards, Microsoft's free tier often covers small teams. If you want zero licence costs, I can build a custom web dashboard instead — it runs in any browser.
How do you handle my business data? Is it safe?
Your data stays confidential — I work under a simple NDA if you want one, never share client data, and delete working copies after handover. Only my open-source practice projects go on GitHub.
What if I need changes after delivery?
Every project includes one free revision round plus 14–30 days of support. After that, small tweaks are usually covered by the monthly maintenance plan (from ₹1,999/month).
Do you work with clients outside Kolkata?
Absolutely — most work happens over Google Meet and WhatsApp. I serve clients across India and abroad. All you need is your data files and 30 minutes for a discovery call.
