Data Engineer2018 - 2020Quartesian
- Created a model to remove the background from images. Wrote a RabbitMQ worker to process the images to make the model available for mobile apps.
- Developed a financial-data webserver able to accept financial statements and perform queries upon them. Used Neo4j to store interconnections.
- Created a facial-recognition system able to remember up to 150,000 unique people and classify them with a low-error rate. I used different types of workers, a few databases, and a few data sources.
- Wrote a module for Android and iOS apps to have onboard-neural networks able to detect, crop, and encode faces to significantly speed up the back-end processing.
- Developed load testing and profiling tools to identify issues and ensure consistency across different devices and services.
- Deployed services using DigitalOcean and wrote custom deployment scripts.
- Developed a custom dashboard to monitor ETL tasks and face recognition data processing.
- Created a service to visualize the WHO Drug database to quickly find medical data by drugs and symptoms.
