A FastAPI service that scrapes SEC Form 4 insider trading data from openinsider.com, stores it in SQLite, and serves it through a secured, rate-limited REST API — built as a backend data layer for my trade journal.

Last week, I finally received the replacement for USB / HDMI Adapter from SunFounder, and I also got a NVMe SSD a couple weeks ago. And now, I can complete the full assemble of my Pi's new house.

I’ve been meaning to write about dates for a while, but somehow never got around to it. While building my Trade Journal Analysis Web App, I ran into a classic developer headache: timezones. I was pulling stock data from Yahoo Finance and displaying ticker information over a date range.

I migrated my Raspberry Pi 5 from its small case to the Pironman 5 case, which offers more space, better airflow, and easier access to all the ports.

About Redis, it only took me ~3 hours to re-deploy FastAPI app with redis, lol.
