Machine Learning Engineer · NLP · Agentic AI · Applied ML

I build and evaluate machine learning systems across transformer-based NLP, semantic retrieval, agentic AI and scientific data analysis. My work focuses on reproducible experimentation, measurable model performance and reliable ML engineering.

Featured Work

  • CareerMatch Agent — Explainable agentic AI job-search system combining FastAPI, LangGraph, semantic ranking, deterministic filtering and evidence-grounded LLM evaluation.
  • Predictive Maintenance ML — End-to-end supervised ML pipeline with model comparison, threshold optimization, calibration, uncertainty analysis and error analysis.
  • DESI-MSI Clustering — Scientific ML workflow using PCA and K-means for high-dimensional mass-spectrometry imaging data.
  • GPU-Accelerated Satellite Simulation — C++/CUDA simulation with CPU/GPU consistency testing and reproducible performance benchmarks.
