01 about

I started out obsessed with aircraft and ended up obsessed with the data they generate — and everything else worth measuring. These days I work across the stack: exploratory analysis, machine learning models, and the orchestration that keeps data moving in production.

Recent work includes deep-learning detectors for AI-generated imagery, LLM-based multi-agent systems, and Airflow environments automating real administrative workloads. I like problems where research meets deployment — where the model has to actually survive contact with the real world.

◉fine-tuningedge AIIoT

Scinfaxi — AI-Image Detection

A fine-tuned detector for AI-generated imagery that explains itself: every verdict ships as a JSON breakdown across 8 criteria for why an image reads Real or AI. Runs on-device — validated on Snapdragon X Elite, Snapdragon Gen 5, and a Rubik Pi 3's Adreno GPU — or via Hugging Face and llama.cpp.

⣿roboticspython

Picrawler Assistant

A quadruped robot crawler wired up as an interactive assistant — perception, control, and conversational commands running on a Raspberry Pi.

▣computer visionedge

Watchdog — Vehicle Sentry

A DIY 'sentry mode' for vehicles that never shipped with one. Object detection on a mobile compute unit acting as a dashcam watchdog for non-IoT cars.

⇌MLflowdrift detectiondocker

MLOps — Drift Detection & Mitigation

A dockerized MLflow environment (MinIO, Postgres) that simulates drift in a live pipeline and triggers the right response — full retrain, doubly-robust reweighting, or incremental SGD updates. An experiment in drift-resistant pipelines and algorithmic bias.

⇶airflowautomation

GAIA — Production Orchestration

A live Airflow environment automating recurring administrative and data tasks at Purdue. DAG design, scheduling, and the unglamorous reliability work that makes automation stick.

🔒 private — Purdue infrastructure
☁AWS GlueRedshift

AWS Glue Pipeline

Orchestrated migration of data from S3 into Redshift with Glue, plus downstream visualization. Includes the scripts and queries used to validate every stage.

⛴dockersparkhadoop

Dockerized Airflow Pipeline

A processing pipeline orchestrated by Airflow and deployed via Docker, moving data through S3, Spark, and Hadoop end to end.

∿deep learningtime seriesgeospatial

Census-Tract Unemployment Forecasting

A bidirectional LSTM forecasting weekly unemployment claims across Indiana census tracts, mapped with choropleths and heatmaps. Took 2nd place in Purdue's IronHacks data science competition.

Airspace Density & COVID-19

Quantitative comparison of airspace density over major US airports before and during COVID-19 — measuring exactly how hard the pandemic grounded air travel.

σsix sigmaDMAICprocess improvement

Six Sigma — Honors College Lead Time

A DMAIC overhaul of a Purdue Honors College process that demanded manual review every semester. Mapped the key phases, isolated the bottlenecks, and cut lead time from 107 days to 21.
