OVERVIEW
This project explores large-scale football data processing using distributed computing. The goal was to design and implement a pipeline capable of ingesting Bundesliga datasets, storing them across a distributed file system, and generating actionable insights on team and player performance through SQL-based analytical querying.
PROBLEM
Football datasets carry large volumes of structured information — match results, possession data, league standings, and multi-season trends. Traditional single-machine approaches become inefficient as this data grows, requiring a system built on distributed computing principles instead.
SYSTEM_ARCHITECTURE
Raw Bundesliga Dataset
Match results, team stats, historical records
Data Ingestion
Structured intake of raw football data
HDFS Storage Layer
Distributed storage across the file system
Data Processing Layer
Cleaning, transformation, aggregation
SQL Analytics
Analytical querying over distributed data
Insights & Reporting
Performance trends and team comparisons
KEY_FEATURES
Distributed data storage using HDFS
Large dataset processing
SQL-based analytical querying
Performance statistics generation
Team comparison analysis
Historical trend analysis
Scalable data workflow design
ANALYTICAL_QUESTIONS
Examples of the questions the pipeline was built to answer.
Which teams scored the most goals?
Offensive output ranked across squads using aggregated match-level data.
Which teams had the best defensive records?
Goals-against and clean-sheet frequency compared across the league table.
How did teams perform across seasons?
Season-over-season trend lines built from historical standings data.
What performance trends emerged over time?
Pattern detection across multi-season aggregates at the team level.
Which clubs demonstrated the most consistency?
Variance in season-to-season performance used as a consistency signal.
TECHNICAL_CHALLENGES
Distributed storage concepts
Understanding how HDFS partitions and replicates data across nodes, and what that means for query design.
Hadoop ecosystem fundamentals
Getting from zero to a working mental model of the Hadoop ecosystem and how its components fit together.
Efficient analytical queries
Designing SQL-style queries that stay performant as dataset size scales up.
Large structured datasets
Handling football data at a volume where naive, single-machine approaches stop working.
Data preprocessing workflows
Building a repeatable pipeline for cleaning and shaping raw data before analysis.
Big-data performance tradeoffs
Reasoning about the tradeoffs between storage layout, query design, and processing cost.
WHAT_I_LEARNED
OUTCOME
The project demonstrated how distributed computing can process and analyze large football datasets end to end. It provided hands-on experience with Hadoop, HDFS, and SQL-based analytics, reinforcing principles of scalable system design and data-driven decision making.
WHY_THIS_PROJECT_MATTERS
This project demonstrates my ability to move beyond frontend development into data engineering and analytics workflows. It reflects a growing interest in large-scale data systems, distributed computing, and AI-driven decision support — complementing my professional experience in frontend engineering and my MSc studies in Applied Data Science & Artificial Intelligence.
