- For 8 weeks implemented from scratch an HTTP proxy for a 3-rd party web service. It was a pilot go-swagger integration. - During a week along with other tasks had rewritten ASN.1 parser from Perl to Python. - For 2 months implemented back end part of in-app subscriptions and consumables. Both, for ios and android. To ensure reliability it was done using the saga pattern.
Managing and tuning any aspect of a software development process. Goal-oriented, of course. The scripting language of my choice is Python. So Ruby/Perl/PHP/Lua in read-only mode, please. Another dedicated specialist to delegate this works too. Skype/mobile/telegram - at your request.

On my previous job I developed several projects which I very proud: - Continue watching system for video streaming platform: From the very beginning I myself analyzed and thought out a system for storing and processing time stamps that contain information on the time each video was viewed by users on the platform. I thought about how to store these timestamps and in which of the database. How to transfer information to frontend clients. How to make the system resistant to high loads and to make it so it was easily to develop by other developers. - On another project, we started split the monolith into microservices. I integrated Apache Kafka into the system to synchronize part of the information through the kafka. It was error sensitive information that could not be lost, that's why we use Kafka instead http. Also If we used http we ddos our own system. This system began to be used by other projects in this company. and more interesting projects...:)
Looking for interesting projects, challenging task, new opportunity, various language and various technologies. Always wondering to develop big distributed application.

The last project was creating payment gateways for crypto currencies. During my careerer I worked in outsource, product, state companies and startups. I have experience managing a small team (5-7 members). I won a large number of international hackathons (Germany, Singapore, USA). I write technical articles, speak at international conferences and work as lectura in universities (HSE, Moscow and VSU, Voronezh). I'm interested in projects which improve business processes or provide new technologies to customers. As a professional I'm more interesting in growing as solution architect and team lead than simple developer.
Winner of more than 10 international hackathons. Successfully launched high security project in very short term with small team without full set of requirements.
Not interested in work in CIS. I'm looking for the company with interesting projects in a friendly atmosphere.
