I had made a small code contribution to RxSwift community.
I would like to take part in development of a large complex app being in a big team sharing my knowledges and learning new awesome practices and edge technologies. No old legacy code base, not micromanagement, please.

My previous jobs: 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. Then I was a part of Ukrainian product that simplifies time-consuming and complex interaction in B2B for restaurants and their suppliers. The main idea was to automate processes that take away the energy and resources of those companies, thereby to save time for their development and growth and to show that ordering automation saves time, reduces stock and prevents lost-sales for both the restaurant and the supplier. Responsibilities: 1. Scala back-end development and partly front-end. 2. Monitoring performance of the project and integrating new ways of analyzing data and processes, also negotiating with clients and implementing solutions that are convenient for them. 3. Implementing auto-ordering system that forms orders based on sales data and commodities balances from POS-systems.

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 cryptopanic.com, twitter.com, reddit.com. 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.

There is a desire to "switch" to Scala, but I haven't commercial development experience in this language. It would be nice to get into a project where involved in data processing - I’m interested in this kind of technology stack: spark, hadoop, kafka, akka, cassandra, mongodb, aws etc. But this is absolutely not necessary:) I am also pleased to consider vacancies related to FinTech. Also: - Paid sick leaves and vacation - Payment of medical insurance - English course - Ability to work remotely when needed and flexible schedule - Bookkeeping (taxes) - Professional growth - Informal atmosphere - Friendly staff Don't offer "full stack" positions. There isn`t desire to work with "front-end".

Design system from the ground up to working commercial system. Have an experience implementing microservices and designing the whole reactive system from the ground up. My primary technology stack in use now is Scala (not as a "better Java", but rather as "like an impure Haskell"). But I also have commercial experience on the lower level up to C and assembly in embedded. I had a commercial experience with Clojure and even Common Lisp, but left the land of dynamically typed languages for goodies that static typing may offer.

Implemented a DSL interpreter with type checking/type inference. Had made a couple of talks on local Scala related meetups and conferences.
Backend developer position where "bulletproof" software and architecture is preferred over "do it here and now and later will fix the mess". Or at least the consequence of this "later fill fix the mess" is understood well by all participants :) The more specs we push to the type level and make the compiler do the jobs - the fewer bug reports we'll get later. Readability and maintainability of the code go first, dirty hacks to speedup come only after the bottleneck is identified. Flexible working hours with remote work possibilities (both occasional time to time and full remote).
