My previous job: I was a member of data engineering team that designed Big Data tools and infrastructure for the project that included collecting, processing and analyzing large amounts of (un)structured data mostly from web APIs and different data storages which were in most cases associated with visitor behavior, clickstreaming, marketing, etc. The main idea was to build a platform that provides a data set of all needed online data for businesses and use that data for APIs to improve product recommendations, conversion rate, ads, etc. Responsibilities: 1. Implementing and designing data pipelines. 2. Scala back-end development of microservices. 3. Monitor performance of the project and integrate big data tools. 4. Doing code review, work with other teams including DevOps team, thus improved my skills in this area too.

Before my previous job I took internship at a company, where I was studying Data Engineering, Scala, akka and other tools and concepts for building highload and distributed systems. Also participated in the final project there, which was basically an analyzer to estimate impact of news on cryptocurrency prices for given time frame in the future with given prediction frequency. As a result, it was a system that monitored sources and evaluated the importance and impact of the news. Based on this it predicted the consequences in short and long time interval. My responsibilities were: 1. Giving and collecting data for data scientists from various resources like,, 2. Building a REST API on Scala. Also. I made some personal projects, like: 1. Admin panel for monitoring orders from hardware stores. It was a university course project which was basically a web-app for monitoring orders from various stores, finding stores nearest to the customers, collecting basic info from employees, store owners, orders' status etc. Designed microservices architecture of the app, implemented backend and frontend, build containerized network of created modules. 2. Project for building a system for cafe without queues. The idea was to build a system for a cafe without cashier attracts queue. My part of the job was to develop a backend part of the system. Moreover, I have certificates from my internship and also from some online courses. like Coursera.

Worked with different Scala and Java projects. Low level (platform that communicates via network with small devices, detectors and so on) and high level web apps. With synchronous and reactive behaviours. REST and messaging based commucation. Etc... Latest experience: casino platform with Scala, Lagom, Play, Akka, Kubernetes, Cassandra, Kafka, ElasticSearch, GraphQL.

Full time or part time, preferably remote. Or if office - preferably flexible with possibility to take some day-offs (1+ days non office work). I prefer Scala projects. Would be a plus to have ownership over the code: not only code, but be tester and devops for it. So, having tasks to work with infrastucture also. Woud be be a plus if there is need to work with frontend (React for example). Would be great if you need 2 Scala devs. I have a colleguage with who we want apply to same project.
