Data Analyst & Analytics Engineer
Ridwanllah Husain
I build the data layer underneath a business, then the reporting that runs on it. Most of my work comes down to finding where value quietly goes missing, and what it would cost to stop it.

I turn messy data into numbers a team can actually decide on.
I'm a data analyst and analytics engineer, and I work the whole way through a problem: getting data out of the systems it's stuck in, shaping it into something you can trust, then building the reports and dashboards a team checks every week. Most of the value sits in that middle part, where a number either survives being questioned or it doesn't.
I studied electrical engineering, so I usually want the reason behind a number rather than just the correlation, and I'll tell you where an analysis stops being reliable before anyone builds a decision on it. The pipelines matter for the same reason: scheduled ETL, a warehouse designed in SQL, loads that are safe to rerun, and checks that catch bad data before it reaches a report.
Available now for full-time analytics roles and freelance work: dashboard builds, one-off analyses, predictive models, and pipeline setup for teams that don't need a full-time data hire yet.

What I Build
Exploratory work, segmentation, cohort breakdowns and the recurring reports a team runs on. You get the numbers, the reasoning behind them, and a straight answer on what they do and don't tell you.
Interactive dashboards in Power BI, plus lighter app interfaces where a full dashboard would be overkill. Built around the questions people already ask, so they can find answers without coming through me.
Data modelled properly: clean tables, a sensible grain, and metric definitions written down. This is the layer that keeps every report consistent instead of each one quietly telling a different story.
Scheduled pipelines with retries, backfills and quality checks built in. When something breaks you hear about it that day, rather than finding out from a wrong number a week later.
Classification, scoring and forecasting models, tested on data the model hasn't seen and calibrated so the probabilities mean something. Handed over with a plain read on how well it performs and where it falls down.
Selected work
Featured Projects
All projects →Nigeria Electricity Grid Analytics
Every stage of the chain on one grain, from generation through to cash collected. ₦2.0 trillion of the ₦7.8 trillion billed never comes in, and the simulation puts metering ahead of new generation as the first fix.
CS $ stack · Python · Machine Learning · SQL Credit risk · Live app↗Credit Scoring Application
First-time borrowers default about eight times as often as returning ones, and a single pooled model was averaging that difference away. Scoring each group separately holds up at 0.76 AUC on later, unseen data.
EP $ stack · Python · Machine Learning · FastAPI Energy · Forecasting↗EnergiPredict — HVAC Consumption
The demand side of the grid work: predicting cooling load in large university halls so that setting a temperature comes with a visible cost attached. Five models compared, and the stacked ensemble came out ahead.
AF $ stack · Airflow · Redshift · Python Data engineering · Article↗Orchestrated ETL Pipeline
Pulling property data from the Zillow API through to Redshift on a schedule, with Airflow handling the ordering, the retries and the backfills so nobody has to babysit a run.
FD $ stack · Python · Machine Learning · FastAPI Fraud · Served API↗Fraud Detection API
Transaction scoring behind an HTTP endpoint, containerised and shipped through CI. The write-up includes the leakage checks I ran on the headline score, since a near-perfect result on fraud data usually means something is wrong.
LR $ stack · Python · Machine Learning · Pandas Machine learning↗Lagos Rent Predictor
Rent estimation for Lagos apartments, taken from collecting the listings through cleaning them to a model you can put a real property into.
