The most amazing... I've built is a tool for mixing different Java ME apps into one multi-app with multitasking, allowing users to view multiple apps at once.


  • Senior Java Developer

    2011 - 2012
    • Member of a team working to implement a complex web project. The project included a variety of user services that were made accessible through a single account to provide a unified, user-friendly experience.
    • Contributed to the design and overall architecture/infrastructure of the project.
    • Designed and implemented the JSON over HTTP protocol for client-server communication. This included CDI integration, rich options for access control, security, and routing.
    • Included support for both for Java and ActionScript runtimes, dramatically boosting the productivity of both the Java and Flash teams.
    • Developed a fully automated ActionScript code generator to build a facade for the protocol. This included service interfaces, client factories, configuration, data transfer objects, type-aware (de)serialization, error handling, and queuing.
    • Optimized SQL code for complex queries.
    • Worked in management and maintenance of the infrastructure for the distributed app servers. Initiated and completed the migration from GlassFish to JBossAS 7.
    • Developed an extensive online storage system with filtering, access control, sharing, searching, and video/audio/image processing.
    • Wrote a majority of the code for every subsection of the project, including storage, social networking, private data management, and the notification system. Designed APIs for nearly every service developed.
    Technologies: Java Core, CDI, JPA, Servlets, JMS, ActionScript
  • Software Developer

    Alt-M Technologies LLC
    • Developed a platform for premium SMS services, including a backend system for SMS processing, provider/partner integration, billing, and reporting.
    • Created a LAMP based mobile entertainment site.
    • Created a mobile casino system with Java ME clients and a OSGI/PostgreSQL based backend.
    • Designed a TV show platform, including server-side (OSGI/PostgreSQL) services for player-interaction via SMS, support for Java ME clients, a mobile website, and a manager’s web interface.
    • Developed a service to enable customers to easily and reliably send SMS notifications. This involved a backend system (OSGI/PostgreSQL/CouchDB), integration with upstream SMPP-providers, message delivery and processing, scheduling, accounting, reporting, and a web based (JavaScript RIA) frontend for managing contacts and campaigns.
    Technologies: Java, OSGI, Java ME, PostgreSQL, MySQL, CouchDB, PHP, SMPP


  • MULTiME (Development)

    A worldwide-unique project that overcomes a major MIDP-1.0/MIDP-2.0 limitation that restricts the user to only running a single application (midlet) at a time. The project is a constructor for mixing several midlets into one - a “multi-midlet”, allowing for use of them simultaneously within an emulated multi-tasking environment.

  • [email protected] (Development)

    An “internet-to-sms” messaging project with mobile/web clients.

  • BomberField (Development)

    This is an online real-time multiplayer game that is currently under development.

  • WideUP (Development)

    A multifunctional platform for the online business sector and private space.

  • youdrive (Development)

    A driving-related Ukrainian site that is currently on hold.

  • View-First Java Web Framework (Other amazing things)

    A view-first framework for Java that was inspired by Lift. It is based on Java Servlets and integrates easily with CDI. It has not been open-sourced yet. It is user-friendly and runs efficiently, needing just a few ms to generate 500KB responses with 16+ concurrent requests.

  • Advanced UI framework for Java ME (Other amazing things)

    This is a Java ME framework that I've created and used to build a number of applications and games. It is not open-sourced and I have not continued to develop it since iPhone/Android have become relevant in the mobile market, but it is an elegant, efficient framework.
