Hi, I'm Pranav Chavan πŸ‘‹

Applied AI / Data Science Engineer | Computer Vision | Industrial AI

I work at the intersection of data science, machine learning, computer vision, and deployment-oriented AI systems. My strongest experience comes from industrial AI projects, where I developed and evaluated anomaly detection pipelines for real-world inspection data, including a weld-seam surface inspection workflow that achieved AUROC 0.966 and was benchmarked against commercial HALCON software.

I am currently building my portfolio toward data science, operational analytics, LLM/RAG systems, and production-aware computer vision applications.


What I focus on

  • Turning raw data into structured analysis, model inputs, and decision-ready insights
  • Building reproducible workflows for data preparation, model evaluation, and benchmarking
  • Developing computer vision pipelines for defect detection, anomaly localization, and quality inspection
  • Designing AI systems with deployment in mind: Docker, APIs, cloud storage, logging, and monitoring
  • Expanding into LLM/RAG systems for knowledge retrieval, automation, and decision support

Technical stack

Featured projects

πŸ” E-commerce Operational Analytics & A/B Test Analysis

SQL-driven analysis of marketplace order data to understand delivery performance, customer satisfaction, and operational bottlenecks.

What this project shows

  • End-to-end analysis using SQL and Python
  • Root-cause investigation of fulfilment delays and late deliveries
  • Hypothesis testing and A/B-style analysis to estimate business impact
  • Clear communication of insights through metrics, visualizations, and recommendations

🏭 Industrial Anomaly Detection β€” Welding Seam Inspection

Methodology and case-study repository based on my Master's thesis and industrial work at Automation W+R GmbH.
The original code and data are proprietary, so this repository documents the architecture, experimental design, evaluation strategy, and deployment-oriented thinking behind the project.

What this project shows

  • Computer vision pipeline for industrial 2D/3D weld-seam surface data
  • Autoencoder-based unsupervised anomaly detection and defect localization
  • Benchmarking against HALCON with AUROC 0.966
  • Evaluation using AUROC, precision, recall, F1-score, SSIM, MSE, and failure-case analysis
  • Deployment-oriented workflow using Docker, AWS EC2/S3, REST API concepts, Git/GitHub Actions, and Python-based logging

Computer Vision Anomaly Detection OpenCV Autoencoders TensorFlow/PyTorch HALCON Docker AWS

NDA-safe methodology repository based on my Master's thesis at Automation W+R GmbH.
Documents the problem setup, dataset preparation, autoencoder-based anomaly detection, HALCON benchmarking, failure analysis, and deployment-oriented design for industrial 2D/3D weld-seam inspection.

Currently working on

πŸ€– LLM/RAG Knowledge Assistant

I am currently building a retrieval-augmented generation project for domain-specific question answering. The goal is to create a reliable assistant that retrieves relevant context, answers with grounded information, and evaluates response quality using a curated question set.

Current focus

  • Document ingestion and chunking
  • Embeddings and vector search
  • Retrieval-augmented generation pipeline
  • Response quality evaluation
  • Docker-based local deployment

LLM RAG Embeddings Vector Search LangChain Python Docker


Background
