The most amazing...
...work I've done was on a high-performance data pipeline with Spark and Python that processes hundreds of millions of unique data points every day.
Employment
Experience
- Metadroner (Development)http://metadroner.com
I built a search engine for drone and multicopter (mechanically simple aerial vehicle) parts, after getting involved with racing drones and getting frustrated with searching numerous stores for the hobby products I needed. This was built to serve a personal itch, and I'm proud to say that the small community received it quite well. It's grown to serve almost a thousand users.
This project was a solo endeavor, and included building the following:
• A Python-based web scraping infrastructure collecting data on over 25,000 products every day.
• An advanced search engine leveraging Elasticsearch and a Node.js back-end.
• A React single page app front-end.
