LIBS Spectral Calibration MLOps Pipeline · 2026 – Present
A laser spectroscopy (LIBS) analyzer predicts mineral concentration from spectral data, and its calibration model was being retrained by hand in notebooks. I designed an Azure ML pipeline that retrains the model on a fixed schedule (feature selection + ElasticNet), with a versioned database that tracks and audits every model across sample types. A scheduled scoring service writes predictions back into the plant’s process information system. A tiered hot/cold storage design keeps long-term data growth under control.

Mineral Beneficiation Process Optimization · 2026
Built models to predict valuable-mineral losses in a beneficiation (ore concentration) circuit, as inputs for a downstream process optimizer. I built data pipelines that combine process historian, laboratory, pump, flotation, and filtration data. Feature engineering covered stable-period detection, upstream concentration and throughput signals, and process lag measured through cross-correlation. I compared linear and tree-based models and documented the training workflows for handover.

Predictive Pump-Failure Analytics Platform · 2025
Built an end-to-end predictive maintenance system for industrial slurry pumps that combines process sensor data with vibration telemetry. A configuration-driven deployment framework lets new assets be onboarded without code changes, with separate non-production and production endpoints. I also found and fixed a preprocessing bug in the legacy pipeline that had been discarding over 90% of training data.

Computer Vision for Haul Truck Monitoring · 2026
Proof-of-concept systems that use existing CCTV feeds to detect dump trucks and classify whether they are loaded or empty. I evaluated object detection and segmentation models against vision-language models for the classification step.

Root-Cause Analysis for Fertilizer Plants
Applied multivariate, time-lagged analysis to sensor data from urea and ANP plants to trace the process conditions behind production losses, and turned the findings into recommendations operators could act on.

VLM-Assisted Data Annotation for PPE Detection
Used vision-language models to generate annotations for a custom PPE detection dataset in-house, avoiding both manual labeling and public annotation tools for confidential images. Read the write-up →
