-
Data Foundations & Dark Data Landscape
4 weeksGoals
- Understand what dark data is, why it accumulates, and the business case for analyzing it
- Build fluency in Python for data manipulation and SQL for structured querying
- Learn to navigate cloud storage systems (S3, Azure Blob, GCS) and identify data types
Resources
- IBM Research: 'Dark Data - What It Is and Why It Matters' (whitepaper)
- Python for Data Analysis (Wes McKinney) - pandas fundamentals
- Mode Analytics SQL Tutorial (free)
- AWS S3 / Azure Blob Storage documentation and free-tier labs
- Coursera: 'Introduction to Data Engineering' by Duke University
MilestoneYou can inventory a sample data lake, classify data by structure type, and write Python scripts to profile file formats and metadata.
-
Unstructured Data & NLP Essentials
5 weeksGoals
- Master core NLP techniques: tokenization, NER, TF-IDF, topic modeling, and summarization
- Learn to parse documents, emails, PDFs, and logs using Python libraries and OCR tools
- Gain hands-on experience with HuggingFace Transformers for text classification and extraction
Resources
- HuggingFace NLP Course (free, comprehensive)
- spaCy documentation and tutorial notebooks
- AWS Textract / Azure Form Recognizer quickstart labs
- Real Python: 'Working with PDFs in Python'
- Kaggle: NLP competitions (disaster tweets, feedback prizes)
MilestoneYou can ingest a mixed corpus of PDFs, emails, and log files, extract structured entities, and build a topic model that summarizes the content.
-
LLM-Powered Analysis & RAG Pipelines
5 weeksGoals
- Learn prompt engineering patterns for data extraction, summarization, and classification
- Build a RAG pipeline using LangChain or LlamaIndex with a vector database backend
- Understand embedding models, chunking strategies, and retrieval quality evaluation
Resources
- LangChain documentation and cookbook examples
- LlamaIndex documentation (formerly GPT Index)
- DeepLearning.AI: 'Building and Evaluating Advanced RAG' (short course)
- Pinecone learning center: vector search fundamentals
- OpenAI Cookbook: embeddings and retrieval use cases
MilestoneYou can build a working RAG system over a dark data corpus that answers natural-language questions with source citations and confidence scores.
-
Pipeline Engineering & Data Governance
4 weeksGoals
- Design automated ingestion and enrichment pipelines using Airflow or Prefect
- Implement data quality checks with Great Expectations and maintain a dark data catalog
- Learn GDPR, CCPA, and HIPAA fundamentals relevant to dark data handling
Resources
- Apache Airflow official tutorial and best-practices guide
- Great Expectations documentation and example suites
- Prefect 2.x tutorials
- IAPP: 'GDPR for Data Professionals' (free primer)
- dbt Learn (free course) for transformation best practices
MilestoneYou can deploy a production-quality pipeline that ingests, validates, enriches, and catalogs dark data on a scheduled basis with automated quality alerts.
-
Portfolio, Specialization & Job Readiness
4 weeksGoals
- Complete 2-3 end-to-end dark data analysis projects and publish them on GitHub
- Specialize in one vertical (healthcare, finance, legal, manufacturing) and learn its data regulations
- Practice interviewing, build a portfolio site, and contribute to open-source dark data tooling
Resources
- GitHub portfolio best practices for data professionals
- Industry-specific datasets (MIMIC-III for health, Enron emails for legal/finance analysis)
- Open-source contributions: LangChain, HuggingFace, Great Expectations issue boards
- Mock interview platforms: Pramp, Interviewing.io
- Personal blog or Medium publication for case studies
MilestoneYou have a polished portfolio with 3 deployed dark data projects, a vertical specialization narrative, and can confidently interview for AI Dark Data Analyst roles.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Dark Data Discovery Dashboard for a Public Dataset Lake
BeginnerIngest a large public dataset repository (e.g., a Kaggle dataset dump or AWS Open Data), profile all files by type, size, format, and estimated content, and build an interactive dashboard that visualizes the 'dark' vs. 'active' data ratio.
Email Archive Intelligence: NER and Sentiment Analysis on the Enron Corpus
IntermediateProcess the Enron email corpus using NLP - extract named entities (people, organizations, dates, financial amounts), classify sentiment, build a communication network graph, and surface the most anomalous communication patterns using topic modeling.
RAG-Powered Dark Data Query System for a Simulated Corporate Knowledge Base
IntermediateBuild a LangChain/LlamaIndex RAG system over a mixed corpus of PDFs, markdown files, and CSV reports. Implement chunking strategies, embed with OpenAI or open-source embeddings, store in Chroma or Pinecone, and create a conversational interface with source citations.
Predictive Maintenance Signal Detection from IoT Sensor Logs
AdvancedWork with a large-scale IoT sensor dataset (e.g., NASA Turbofan Engine Degradation). Build feature engineering pipelines on raw sensor time-series, train unsupervised anomaly detection models (isolation forest, autoencoders), and create an alerting system that predicts failure events before they occur.
Enterprise Dark Data Monetization Proof-of-Concept
AdvancedDesign and implement an end-to-end dark data product: ingest a multi-source dark data corpus (text, images, tables), build a unified searchable index using hybrid search (keyword + semantic), create a data quality and lineage tracking system with Great Expectations and dbt, expose an API for querying, and draft a data product spec with pricing tiers.
