Flight Log
Batch ETL Pipeline with Airflow & PostgreSQL
2025
- Python · Apache Airflow · PostgreSQL · Docker · CoinGecko API
- Built a batch ETL pipeline extracting daily cryptocurrency data from the CoinGecko API, transforming with Pandas, and loading into a PostgreSQL star schema (fact_prices, dim_coins, dim_date).
- Orchestrated with Airflow DAGs including retries, idempotency checks, and failure alerts; containerized with Docker Compose.
Web Scraping Pipeline with CDC & FastAPI
2025
- Python · Scrapy · FastAPI · PostgreSQL · Airflow · MinIO
- Built an automated scraping pipeline detecting changes over time via Change Data Capture, implementing SCD Type 2 in PostgreSQL and exposing trend data through a FastAPI REST API.
Job Application Tracking Platform
2024
- FastAPI · PostgreSQL · SQLAlchemy · JWT · pytest · GitHub Actions
- Built a REST API backend for tracking job applications with JWT auth, role-based access, and a normalized PostgreSQL schema via SQLAlchemy ORM.
- Added pytest test coverage and configured GitHub Actions CI/CD for automated testing and deployment on every push.
RAG-Based Document Q&A Research Assistant
2024
- FastAPI · LangChain · pgvector · OpenAI/HuggingFace
- Built a Retrieval-Augmented Generation system for natural language Q&A over uploaded documents using pgvector similarity search and LangChain retrieval chains.
