My tasks were to write scripts to work with a large amount of data in Cassandra and ElasticSearch. The amount of data in Cassandra alone reached 300GB, it was required that the scripts work fast enough and did not take several days.Participated in a cross-review.Participated in the release process.Converted business requirements into technical documentation.I worked with AWS, almost all the infrastructure was there.Conducted interviews for developers.Achievements:* Improved the script for transferring and updating data from cassandra to elasticSearch. First, I implemented its work in multi instance mode using Kafka, which significantly accelerated the script's work on big data (from ~ 1 day to several hours). After that, I optimized the algorithm, which reduced the operating time by another 2-4 times.* Improved the service for running scripts processing data in Cassandra. I also switched them to multi instance mode using Kafka.

Worked on 3 different projects.1) An entertainment system, the essence of which is to create a video clip of a customer's race in a go-kart center. My main task was to develop a web application on the MEAN stack, which had a major role in this system: it collects and processes streams from video cameras installed on the track; monitors kart state; assembles client videos from templates and collects statistics on them; and sends clients their videos. I have been working on the project for more than six months, and for the last 2 months I have been solely responsible for its transformation. I've modified video processing algorithms, communication algorithms, the video build system and redesigned the front. I have made this system stable and minified amount of errors.2) Video analytics system. I have modified analytics core written on C++ for integration with the web interface and took part in developing web-interface including web-socket connection to the core, rest api, visualizing reports. 3) Face Recognition System. Spent a lot of time testing is. Modified sources to work with intercom.
