CCC-2022 T4A2 - Full Stack Application - Karl Alberto
N.B. Updated from original project here due to shift in tech stack.
Sindarin Translator Online is a web interface for the terminal application I created in Term 2 (2021) for the CCC course (T2A3). You can find more details about that project here.
Documentation and Development updates are available via Trello here, along with screenshots below.
Website is hosted on Amazon EC2; built with Python using the Flask web framework. Frontend is HTML5 with Pico.css framework. Amazon DynamoDB is used as a cache for translations, with a 24-hour Time-To-Live (TTL) setting. AWS IAM and AWS Parameter Store are used for account management and secret key storage, respectively. Version control is handled by Github.

- Easy to use, responsive website

- English-to-Orcish
- Output text in Tengwar (Elvish) script
