Compares Ookla's self-selected speed tests against RURA's full subscriber census, then models the probability a location enters the crowdsourced sample to correct for it. Thirty quarters of measurements, terrain, and technology mix pulled from 28 regulator PDFs feed an out-of-fold calibration step.
An end-to-end pipeline that simulates live transaction traffic and scores it in-flight. Predictions split two ways: Postgres for a low-latency Streamlit dashboard, HDFS as a data lake for batch analytics and retraining.
A fully containerized clickstream pipeline that predicts whether a shopping session will end in a purchase while the session is still in flight, surfaced on a live dashboard. Built with a five-person team for AUCA's Big Data Essentials course.
Ingestion and analytics pipeline for smart-grid sensor data. Devices publish over MQTT through EMQX into a Postgres/TimescaleDB store, surfaced through Grafana boards and an interactive Streamlit dashboard.
A Master's-level benchmark comparing MapReduce against Spark on the IEEE-CIS fraud dataset (590,540 transactions, 394 columns), measuring performance and implementation complexity, not just output.
Where the data work meets a real product: deployed for actual users, not just a notebook.
