    Technical Project Manager

    United States - Last active: 4 months ago - Tests: 2 - Portfolio: 2

    I'm a technical project manager, focusing primarily on agile software development. I've been handling web and video-related projects for over 4 years, with an additional 12 years' experience as a systems engineer. I've been managing teams of up to 6 people on projects lasting 3-9 months. My responsibilities include: communicating with the client to have a good understanding of the business requirements; verifying that the feature requests are achievable under the time/budget restraints; creating a quotation to specify cost and estimate timeline; choosing the right team for the project; creating a functional specification to ensure that the client and my team are on the same page; supervising the development to help and motivate my team in achieving set goals on time; presenting the results to the client and classifying any discrepancies as either bugs/faults or new feature requests; deploying the systems and supporting the client. Some of my technical achievements include: writing a Sony-specific EBU-STL to SRT subtitle conversion script in python; creating STB-compatible MPEG2-TS profiles for VOD (w/subtitles); deploying a custom Alfresco implementation in JBoss using AMPs for backend modifications and a unique front-end based on a stripped-down version of Share.
