MLOps Project
Course project applying end-to-end MLOps practices (reproducibility, CI, Docker, deployment, monitoring) to a machine-learning pipeline, with the tabular CNN baseline being replaced by an MLP.
- • Structured an MLOps repository with configs, data splits, tests, reports, and documentation
- • Set up reproducible environments and dependency management for ML workflows
- • Versioned data and experiments for traceability and rollback

Image Analysis - Jupiter
Processed Juno Advanced Stellar Compass images to calibrate/denoise frames, detect Jupiter’s limb, map stars to a catalogue, and estimate camera attitude with validation against SPICE geometry.
- • Radiometric calibration for CCD imagery: dark-frame subtraction and removal of fixed-pattern/column-correlated artifacts
- • Radiation/cosmic-ray style artifact suppression with conditional (gradient-based) filtering that preserves PSF-like stars and limb edges
- • Despinning interleaved odd/even fields by modeling spacecraft rotation in the camera frame and remapping via bilinear interpolation
