Case studies
Projects
14 pieces of work, written up in full — the problem, what I designed and why, what changed, and what I would do differently. Nine of them use public datasets and can be shown end to end, screenshots and all.
Screenshots of live humanitarian systems are not published. Where visuals appear, they are illustrative rebuilds created with synthetic data that reproduce the structure and design of the original work without exposing any operational or personal information — on data-protection grounds.
Predicting Dengue from a Routine Blood Test
A screening model built on real hospital haematology from Jamalpur, tuned to catch 96% of dengue cases — because during an outbreak, a missed case costs more than a false alarm.
Retail Demand Forecasting & Decision-Support Dashboard
A Design Thinking build on a large public grocery-retail dataset: a tuned Random Forest demand model, benchmarked against XGBoost, delivered as a decision-ready Power BI dashboard and validated by expert heuristic evaluation.
RAMS — Registration Asset & Materials Management System
A Model-Driven Power App that became the single source of truth for registration stock, supply, procurement and vendor management across the Cox’s Bazar office and eight registration sites.
ID Card Project — Activity Tracking Application
Sixteen spreadsheets and fifty-plus users replaced by one Model-Driven Power App — turning a two-day manual reporting exercise into a thirty-minute one.
Registration Operations Dashboards
The reporting layer for the Biometric Identification Exercise and the ID Card Project — daily, weekly and monthly Power BI reporting to management, plus camp-wise reports for government counterparts.
E-Commerce Customer Analytics — RFM Segmentation & CLTV Prediction
Half a million transactions reduced to five customer segments, then a gradient-boosted model that predicts what each customer will spend over the following three months.
IBM HR Analytics — Employee Attrition Console
A four-page Power BI console that takes a flat HR file with no dates in it and still answers the three questions an HR director actually asks: who is leaving, why, and who is next.
Global Superstore — Performance & Profit Leakage
A four-page Power BI report over 51,290 order lines that answers a question the sales chart hides: revenue nearly doubled in four years, so why did margin go backwards?
Bangladesh Food Price Intelligence Dashboard
Twenty-six years of World Food Programme price data — 14,178 observations across 74 markets — turned into an interactive Power BI tool for tracking food inflation, regional disparity and supply-chain margin.
Bangladesh Police — Crime Analysis & Law Enforcement Effectiveness
A decade of national crime statistics — 1.09 million cases across eleven categories — analysed to test whether enforcement activity actually kept pace with crime.
Bangladesh District Population & Growth, 1991–2022
Thirty-one years of census data across all 64 districts, built in Tableau and published publicly — an interactive view of where Bangladesh actually grew.
Customer Lifetime Value & Marketing Campaign Analytics
A campaign programme running at a net loss per cycle, and the segmentation work that shows exactly which customers it should have been aimed at instead.
File Management System Overhaul
Leading a team of fourteen to clear a backlog of over a million physical refugee files and restructure the archive — an operations and team-leadership problem more than a technical one.
Large-Scale Registration Operations
Four concurrent registration exercises from 2018 to the present — joint verification, continuous registration, headcounting for new arrivals, and biometric identification.
