Brightpmk/README.md

Computer Engineering student at Chulalongkorn University
Focused on building scalable ETL pipelines and AI-powered analytics systems.

🛠 Tech Stack

Data Engineering & Analytics:
Python SQL Pandas PostgreSQL SQLite Power BI Plotly

AI & App Development:
Streamlit OpenAI

Core Engineering & Tools:
Java C++ Docker AWS Git

🏆 Flagship Project

🚀 Olist E-commerce Analytics Platform

An end-to-end data platform unifying ETL, Star Schema Modeling, and LLM-powered Insights.

I integrated my previous work on data cleaning, strategic analysis, and AI development into one comprehensive ecosystem. This project demonstrates my ability to handle the entire data lifecycle.

Key Achievements:

  • 🏗️ Robust ETL Pipeline: Built modular Python/Pandas workflows to extract and validate 100k+ records from raw Brazilian e-commerce data into PostgreSQL.
  • 📊 Architectural Modeling: Designed an analytical Star Schema (Fact & Dimension tables) to optimize complex revenue queries and RFM segmentation.
  • 🛡️ Secure AI Assistant: Integrated OpenAI API with Streamlit to convert natural language to SQL, featuring a safety validation layer to prevent destructive commands (DROP/DELETE).
  • 📈 Actionable Insights: Automated the generation of business KPIs and interactive Plotly visualizations directly from chat prompts.

Tech Stack: Python · PostgreSQL · Streamlit · OpenAI · SQLAlchemy · Pandas

🔎 Professional Focus

  • Data Engineering: Incremental loading, performance optimization, and pipeline orchestration.
  • Data Modeling: Designing efficient relational schemas (OLAP) for business intelligence.
  • AI Integration: Building safe and reliable LLM-based interfaces for data exploration.

🎯 Current Goals & Learning

  • ☁️ Scaling data workloads using AWS (EC2/S3).
  • 🔄 Mastering workflow orchestration with Apache Airflow.
  • 🐧 Strengthening Linux systems administration and deployment.
"Transforming raw data into strategic assets."
