Social Quantum Kiev (AvenueGames studio)

Dates of Employment: Jan 2014 - Jun 2016

Position: Team Leader/ Lead server side developer.

Managing team of 3 developers.

Developing HTTP game server for online game Wild West. We were starting with old solution on Ruby 1.8.7 with Postgres 8 which we migrated to Ruby 1.9.2 and later 1.9.3 to provide support for latest PostgreSQL. While working with old server we were continuously improving and reorganizing entire application. So at the end we had almost brand new server that hold up to 3000 active users per instance. According to Ruby GIL limitation we were faced the necessity to run multiple processes of game servers which became our advantage that our system was able to be scaled to 500 instances running on different servers. Working in group of multiple feature teams.
Working on gathering statistics closely with game designers. Writing ruby scripts to collect and make sense of data. Collecting data from production database to teach artificial user for testing purposes. Writing Python socket server to control multiple testing bots. We used Python 3.2 with web sockets to achieve as many bots as possible. Our stress test were run on 10000 bots and it was fine. Writing and teaching Bayesian network based artificial user. We used Adobe Air to be able to run on any
given device as well as take some configs from real game client written on Action Script 3. We successfully achieved our goal of mimic median user in his behaviour.
Feature ownership on neighborhoods. We made a system of 3 server application running and communicating with one another providing user an interacting experience of socket connection on the basis of HTTP server side. Writing an extension to SmartFoxServer on Java 1.7. We had to have some logic on our socket server that is in sync with real game configs so we made a script that generates property files from YAML and then applied them in extension. We did chat message storing to provide user that joins the room with 50 last messages as well as system event storage. We stored rooms and their properties to PostgreSQL and were storing chat to Mongo DB. Writing NodeJS application as agent between Ruby game server and SmartFoxServer for online interactions. We were using Express as HTTP request handler with PBKF2 auth and SmartFox JS library. Application was made with multiple environment configuration to work with multiple env game server. Configuring Capistrano deploy for all application to Unix server. Writing good covered code with Rspec autotests. Using isolation with Mock and Stub to test different parts of game logic.

For the most part we were using Adobe Flash for UI and were developing AS3 code for all game logic Integration of applications to Facebook, VK, OD, Mail.ru Developing AS3 applications for POGO.COM with basically re-creating Java 1.6 game to modern looking and smooth running application Developing game server on PHP for role play game with almost no interaction between users. Providing content through static file transferring with Nginx. Authentication with social network and game logic. Developing AS3 game client for isometric farming simulator. Using Iso3d engine to handle graphics and Interactive PNG to get it all smooth looking. Making cutscenes with Adobe Flash and importing them to game client. Developing Java 1.7 server for farming simulator. We were using Spring for request controlling and Hibernate for database support. We were writing it from scratch to finish with JSON requests and responses Developing game servers with Ruby 1.8 and Ruby 1.9 for farming simulator and city builder simulator. Starting as content developer working on YAML and AS3 look I them became a leader of core team that worked on basic game mechanics as well as optimization of existing server. Optimization of Ruby Sprout deployment of AS3 application which caused us to override Sprout gem to run with our needs.

Freelance

Dates of Employment: Jun 2008 - Jun 2010

Position: Programmer

Responsible:

  • Developing casual mobile games.
  • Developing training application on desktop and mobile
  • Developing casual mobile games with Java 1.6 mobile. Using free images from internet and built in J2ME modules programming games from scratch to finish.
  • Developing Delphi 7 application to speed up learning process for students. Providing complex solutions for mostly mathematical tasks.
  • Indie development of mobile versions of programs that solves mathematical tasks that students could and did use for speeding their homework and mostly for cheating on exams.

Achievements: Developing high load server application for SocialQuantum games. We started basically from scratch and built server that holds tremendous DAU. We used Ruby with Thin and created well optimized game server that handles all game logic for applications. Because oj GIL we had to use multiple instances so our server
is built on idea complete independence of each instance and communication between them was achieved through memcached and async jobs monitoring crucial points.
Working with highly sharded and spreaded database (up to 64 shards) and maintaining ability to interact between users from different shard. We used PostgreSQL and did the best we could with it. Collecting statistical data on users through writing heavy and optimized SQL requests. Constructing async event system to collect and view data on users in system for SocialQuantum and then replicating and polishing it for ABB. I used Sidekiq as async system to perform sending events to stats database. And i constructed entire new application to make sense of the data (it was done at ABB as for SQ had their own) Creating artificial user to test social interactions between real users. We were choosing between deep neural networks and Bayesian network which we choose last. We achieved pretty accurate mimic of users behaviour through playing the game. To train the network we used real data from our stats database. We build a system server on Python that control up to 10000 bots at a time. We built our bots with Adobe Air as it can be executed regardless of platform so it really can be much more of AU doing their job of interacting with each other.
Working and improving e-commerce API to connect low cost airlines with each other to provide lowest price possible to customer. I am feature owner of a module for providing data on airline’s special services like wifi or meals for airlines that aren't actually having those data themselves. Like China West A or KLM international. We used Rails 4 for application, Active Admin for admin panel. We had built controllers that parse NDC XML from airline request and provide with correct NDC response depending on such variables as flight number, origin, destination, frequent flier etc. Setting up full stack application on Unix web server. Usually it is Ubuntu with Nginx, RVM, Git, Eye, PostgreSQL and Capistrano. Also done with Node JS and NPM, SmartFoxServer and Java. Working with Amazon Web Server. Deploying ABB application through VM on cloud service (docker) Feature owning of neighborhoods for SocialQuantum. Setting up SmartFoxServer for immediate
interactions between users. Writing Java extension for controlling and securing user operations on server. Writing Node JS application as agent between HTML Ruby game server and SmartFoxServer socket server. We used Express for Node JS and SmartFoxServer js api (which we mostly rewritten by ourselves to work smoothly). Process of connecting user to neighborhood was like connecting to game server via HTTP and doing authentication, then getting list of not overloaded (below 85% loaded) SmarFoxServer shards, then client chooses best ping and connects to chat with PBKF2 auth. Continuous integration deployment with TeamCity. Setting up and managing all deployment with TeamCity CI and capistrano.
