From business to data analytics.

The fourth industrial revolution didn't just change the tools we work with — it changed who gets to use them. Data isn't an IT skill anymore; it's a working language, and anyone with a real problem to solve can learn it. I studied business. I spent years marketing data & AI to companies. Now I'm building the skills to do the work myself — and sharing every step here.

How I work

Tools change. The loop doesn't.

Every project on this page follows the same discipline: start with a business question, let the data argue, and end with a decision someone can actually act on.

01 · Data

It never arrives clean. Nobody's does.

Nulls, duplicates, a price of $0 and a date from the year 2099. The first job is to understand what the data can and cannot say — and to write down every fix as the business assumption it really is.

C-1041monthly1yes
C-1042NULL14no
C-1041monthly1yes

C-1044Monthly2yes

Found: 1 duplicate, 1 null, 1 impossible value, 1 inconsistent label. Logged, fixed, documented.

02 · Insight

Churn isn't spread evenly. It has an address.

Customers on monthly plans leave in their first two months at three times the rate of everyone else. That's not a statistic — it's an onboarding problem wearing a churn costume.

Monthly-plan churn, months 1–2: 3.1× the baseline. Annual plans: flat.

03 · Decision

Move the retention budget to week one.

Instead of discounting everyone at month six, trigger onboarding nudges and a check-in call in the first fourteen days for monthly-plan customers — and measure it against a holdout group.

About

I didn't leave business. I gave it better tools.

I graduated with a BBA in Marketing from Bahria University in 2024, and spent two and a half years as a Marketing Specialist at traxccel, a data & AI consultancy. My job was to explain how data transforms companies. Somewhere along the way, explaining stopped being enough — I wanted to build.

So I started from the ground up: Python and Pandas for the mechanics, SQL for the questions, statistics for the honesty, Power BI for the story. Then machine learning, deep learning and generative AI for the predictions — and data engineering for the plumbing that makes any of it real.

The advantage of coming in from business is simple: I already know what a dashboard is for. I've sat in the meetings where the numbers had to change a decision. Now I'm learning to be the person who gets those numbers right.

Business fluency

I know the question.

Margins, funnels, retention, positioning — and how a decision actually gets made in a room.

Technical depth

I'm building the answer.

Python, SQL, statistics, ML and the pipelines that turn a one-off analysis into a system.

The overlap

The translation layer — where data becomes a decision.

Most projects fail in the gap between “the model says” and “so we should”. That gap is exactly where I want to work.

The journey so far

Business → Data → AI → Engineering. Click a stage.

Skills

A toolkit, not a badge wall.

Honest levels. “Confident” means I've shipped it in a project; “Building” means I'm using it weekly; “Exploring” means I'm early and say so.

Projects

Learning in public.

Personal projects built on public datasets — Kaggle, UCI, GroupLens and open government data. Each one starts with a business question and ends with a decision. Flip the switch to read the full story.

Playground

Data in motion.

Small interactive pieces I built to understand what I was learning — a dashboard, a theorem, a query, a network and a pipeline. Every one of them runs live in your browser.

This is why a 30-customer survey can still tell you something true about all customers — with a confidence interval you can defend.

A question, in SQL

Which states get the most late deliveries — and how do they rate us?

How a model makes a prediction

Three facts about a customer go in. A churn probability comes out.

Churn risk — move a slider to predict

Let's talk

Let's turn data into decisions.

I'm looking for data analyst and junior data scientist roles or internships — remote or in Karachi. If you have a messy dataset and a real question, I'd love to hear about it.
