I'm Rio Dwi Saputra. Most people just call me Ryo, a self-taught developer from Indonesia 📍. I started out building small games in C#/Unity, then moved into web scraping and reverse-engineering hidden APIs. These days I work across the data stack: ingesting messy real-world data, moving it through Airflow and Kafka, modeling it with dbt, and serving it through FastAPI, with IndoBERT and the Gemini API in the mix for AI-assisted processing.
- 🔭 Currently building: web-scraping engines and data pipelines that turn messy sources into clean, queryable data
- 🛠️ Side habit: turning annoyances into small libraries (see
APIRetrys,Dekimashita, andCathDbelow) - 💬 Ask me about: web scraping, hidden-API reverse engineering, or building pipelines with Airflow, Kafka, and dbt
- ⚡ Fun fact: I'd rather spend an hour automating a five-minute task than do it by hand twice
