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.

02 projects

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.

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.

view repo →
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.

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.
