I’m Polo, blending a passion for data pipelines, automation, and algorithmic trading with hands-on Python projects. Whether it’s wrangling messy datasets or testing trading strategies, I’m driven by curiosity and the thrill of solving complex problems.
A personal reflection on how I transitioned from manually crunching numbers in Excel to building pipelines with Python and Pandas. I share what clicked, what didn’t, and how I’m learning to think like a data engineer — one script at a time.
I walk through how I built my first algorithmic trading bot using Python. From selecting indicators like EMAs and RSI, to setting up backtesting with pandas and yfinance — this article is for anyone curious about the logic behind the code.
Relational or document-based? In this article, I explore the key differences between SQL and NoSQL through hands-on experiments, and how each plays a role in building efficient, scalable data systems.
