Project: SDVI Platform – infrastructure management for the media supply chain

• Built from scratch the core (main) and the job queue manager microservices of the SDVI Platform

• Wrote a few complex UI components, including a visual media verification expression editor

• Designed and implemented a multi-tenant access management backend infrastructure

• Wrote a set or REST services for communication between microservices

• Built a number of deployment scripts, including an object-oriented, easy to configure system data initialization script that supports multiple deployment environments

• Created connectors (third-party integration components) for several third-party media processing and transformation systems

Technologies: Python 3, Flask, SQLAlchemy, Celery, Bootstrap, AngularJS, Postgres, bash, Amazon AWS APIs, gunicorn, nginx, Docker, git, Linux

Project: Media Application Server – a complete media asset management solution

• Worked on a major redesign of the system, including transition to JBoss 7 from JBoss 4

• Improved performance, stability, and maintainability of the system by replacing a number of bash and Ruby scripts and an external RPC server with a shared library written in C and integrating it with the main Java application using JNA

• Redesigned and optimized the persistence layer, in some instances reducing execution time from O(n^2) to O(n log n)

• Wrote a distributed locking component to resolve sporadic issues with database deadlocks and file access race conditions under heavy load

• Built an implementation of FIMS Repository Service – the industry-wide standard API that allows seamless integration between heterogeneous media management solutions

• Added a transparent object-level security layer to the system using an advanced technique that involved intercepting, parsing, and augmenting incoming database queries

Technologies: Java EE, C/C++, bash shell scripting, JBoss, Ant, MySQL, Subversion, Linux

Project: Video Control Center (VCC) - a comprehensive enterprise video platform

• Did integration with a number of third-party digital video encoders, CDNs, transcoders, and a video conferencing solution

• Worked on rewriting the application for the JBoss / Spring / Hibernate tech stack

• Built a completely new UI for the application based on Dojo and Ajax

• Wrote Web service APIs

• Wrote the web management application for the appliance version of the system

Technologies: Java EE, JBoss, Spring, WebFlow, AJAX, JSON, Velocity, Javascript, Dojo, Struts, Ant, Oracle, MS SQL Server, DB2, Eclipse, Maven, Subversion
