Analysed project’s architecture.

Migrated a project from Angular to ReactJS & Redux.
I have studied the specification that has been delivered to my team and I have raised some issues with the document.
Several important aspects of the required implementation were missed and this was a blocking issue since the development team and the testers could not produce and plan their work accordingly.
I had a leading role since I was the first one who read and investigated the abstract specification.

I redeveloped from scratch the backend for this prototype and the migration program. 
I joined a team of three that were mainly focusing on the client side (SWIFT / iOS).
I had to write from scratch the backend since it was missing best common practices and major functionality.
For example instead of using the events for S3 (write, update, delete) a poolling mechanism was in place that after a few hundred entries started not to perfom well.
Major re-write of the REST API was required with some new endpoints.
FInally a data migration was needed from the S3 to a relational database (MySQL/Aurora).
Most valuable IC (Individual Contributor) for three weeks (company-wise).

Designed and implemented a YouTube like application for Aurea’s private videos.
I have designed and implemented with a team of 3 (including the direct manager) a private YouTube system that was reading files from the Google Drive and transferring them to the Amazon's S3.
From there a conversion phase to a common video format and splitting each video to 250MB chunks before feeding them to the Amazon's Transcribing service.
The output (Json text of the video) was saved in MySQL Full text search service in order to serve the Angular UI and make it possible to the end users to locate the specific place of the video that they searched for.
Voting and bookmark sharing facilities have been developed.
This project was not driven by anexisting specification and I was one of the main contributors (brainstorming) about the project's vision/future.

It was a success since it has been used internally by many newcomers who were joining existing projects/teams. It made the knowledge transfer much quicker than usual saving time and money for many contractors.
