Privacy-preserving biometric authentication.

Fottorama is Brazil's leading photo booth software provider. We are currently a one-man development team. Hence, I am responsible for every technical activity in the company. We have a desktop app (C++, Python, Qt, OpenCV), a mobile app (Flutter), and a couple web apps / APIs (Ruby on Rails, Vue.js, Fabric.js, PostgreSQL) which manage user accounts, licenses, payments, and integrations with social networks. Our infrastructure is hosted on AWS (RDS, EC2, S3, SES, SQS, Lambda, Elasticsearch, Route 53, CloudWatch) and DigitalOcean (Docker containerized apps). At the present time, we are testing a new product that employs face recognition (PyTorch, ONNX) to deliver event photos to guests.
