Confidential

Sr. Software Engineer

Responsibilities:

• Developed NMS support for adaptive TDMA carrier technology of efficient Confidential utilization in Confidential 3. 2-X product series, including database, server side, and client side design and development. The quality of the work was recognized by the internal award of Confidential .
• I created the ETL tool for troubleshooting and fixing customers’ corrupted data structure in Group QoS database (MySQL). The software is based on Perl OOD and generalization.
• Worked with Confidential DevOps department for fixing product build process issues that includes Perk and Python scripting
• During 5 years supported all NMS enhancement with new Protocol Processor, Network and VSAT features and types, addressing scalability problems and proxy servers (SNMP).
• All alone conducted and supported Confidential iLicense server - Web application for sale licenses of Confidential Product lines.
• The Ilicense server-client was designed as SPA client on Apache-Tomcat 6, encluded mainly Java and XML development, and MySQL design, ETL, and structure enhancement (J2EE, Jboss, JBPM, Apache, GWT/ Google Web Toolkit, Django, Hibernate)
• Currently, having been designing and developing open-source a web front end tool for big data projects: JavaScript for custom dynamic web controls - tree navigator, extended functionality grid, configurable context menus, and others. Server side includes Hadoop, Cassandra, MapReduce, Stark, Storm, Kafka, as well as programming languages - python and scala

Confidential

Software Engineer

Responsibilities:

• Leading a team of 4 software engineers, designed the high performance server-side soft-real-time framework for NMS system, achieving 1,000 times higher scalable solution than previous (1,000 → 1,000,000 VSAT devices).
• In the project I contributed design of effective parallelism via thread-per-core multi-threading and light-weight synchronization of shared big tree data structure, using of Linux kernel (2.6.24-26) soft real-time scheduling, an original newly created data locking state machine, and multidimensional queuing concept.
• For achieving high performance and scalability, re-factored Network Real-time Data archive - nrd archive is Confidential repository of satellite-based IP communication statistics, exploring Hadoop cluster for big data archive, utilizing analytics with Hadoop for historical requests and custom client reports.
• Integrated described above development into the Agile project management process, improving of development by staging completeness.

Confidential

Sr. Software Engineer

Responsibilities:

• Designing and developing open structure support (OSS) server for future usage in web based NMS.
• I implemented real-time streaming through SOAP protocol between client and server communication.
• Usage of gSOAP tool provided generic programming methodology in design and development of wide range of configuration and monitoring tasks.
• That allowed to increase stability and reliability of replication process from a master server to secondary one(s), and made possible to provide flexible configuration for replication process including several backup servers (C/C++ programming, shell scripting).
• One of my first assignments was improvement of availability of NMS. The common idea of making system more reliable based on replication process of MySQL and servers’ cache in-memory synchronization across primary and hot-ready backup NMS server groups.
