Portfolio
Things I have built and studied — at work, at university and on my own.
Personal project
Data Vizz publishes bar-chart-race videos on YouTube and Facebook. A daily Python pipeline uploads every new video to both platforms with its title, description, tags and a topic thumbnail, and cuts a vertical Short / Reel from it with ffmpeg.
Personal project
This site: all text kept in one content file, rendered to static pages by a small Node script with no framework or dependencies, and served by Cloudflare Workers, in light and dark themes.
SELISE · for a European IT distributor
Maintained Power Automate and Power Query pipelines that turn Dynamics 365 purchase-order data into automated tracking and reminder reports, and traced faults in multi-step refresh chains back to their source data.
Uppsala University · group project
Modelled an assembly line, justified the warm-up period, identified bottlenecks and interpreted the Pareto-front results of a multi-objective optimization.
Published2nd IEOM World Congress · conference paper
Predicts ER waiting times from 5,000 patient encounters, comparing linear models, tree-based ensembles and support vector machines; a tuned stacked ensemble reached R² = 0.9473.
PublishedPLoS One · co-author
Trained and compared KNN, SVM, ANN, Random Forest, XGBoost, AutoML and deep-learning ensembles on original and synthetic datasets, showing how ensembles and synthetic data improve diagnostic accuracy.
Ready for publicationResearch paper
Combines fuzzy AHP, Bayesian Belief Networks and machine learning in a user-friendly interface; the model picks the most suitable supplier with over 95% accuracy.
Ready for publicationResearch paper
Compares ML classifiers on the UCI Heart Disease data — AutoML came out best — then assesses heart-disease risk for predicted cases with a Bayesian Belief Network.
LandQuire
Built automated bots and web-scraping scripts in Python to collect and structure external data, including lead collection.
LandQuire
A project plan for investors in Excel whose Gantt chart builds itself from the plan.
With Rokibul Hasan Parvez
A WordPress site built from custom HTML blocks, CSS and JavaScript, with SEO in mind.
British American Tobacco Bangladesh · internship
Developed a management-trainee platform in Power Apps for the Technical & Training Department.
Personal project
Computes tolerances, tolerance grades and clearances from a basic size and deviations, and generates Go / Not-Go gauge designs.
Personal project
A TCP chat application, a file-transfer tool with a GUI and a relay-server file-transfer system, tested over LAN and VPN.
