Building machine intelligence with a clear signal.

I design and build practical AI systems — from machine learning experiments and RAG pipelines to data-driven products that turn messy information into usable decisions.

Selected Work

Projects with working models, not decorative buzzwords.

P/001
RAG Vector DB LLMs

Document Intelligence Assistant

A retrieval-augmented assistant that answers questions from uploaded PDFs with citations, chunk inspection, semantic search, and confidence-aware responses.

P/002
CV PyTorch

Visual Defect Classifier

Image classification pipeline for detecting visual anomalies using transfer learning, augmentation, confusion-matrix analysis, and lightweight deployment.

P/003
NLP Transformers API

Sentiment & Intent API

A compact NLP service that classifies sentiment and user intent, exposing clean endpoints, logging, validation, and a simple evaluation dashboard.

P/004
Forecasting Pandas MLflow

Time-Series Forecast Lab

A forecasting playground comparing baseline models, feature engineering strategies, cross-validation windows, and experiment tracking for reproducible results.

03

Data Products

Dashboards, APIs, and interfaces that make model outputs understandable.

04

Model Evaluation

Metrics, error analysis, reproducibility, and honest measurement.

Blog / Notes

Short notes from experiments, failures, and rebuilds.

What makes a RAG answer trustworthy?

Notes on citations, retrieval quality, chunking, and why confident language can hide weak context.

Read note

My model failed. The dataset explained why.

A practical debugging checklist for noisy labels, leakage, imbalance, and misleading accuracy.

Read note

From notebook to small API.

How I wrap experiments into endpoints with validation, logging, and a deployment-friendly structure.

Let’s build something that learns clearly.

I’m interested in AI engineering roles, ML projects, research collaborations, and product ideas where machine learning needs to be useful, measured, and shipped.
