PROFESSIONAL EXPERIENCE:

Confidential, Walnut creek, CA

Responsibilities:

• Worked on developing products from a proof - of-concept to product development to final deployment. Developed prototypes of dashboards to display data in tabular and chart formats. Designed and implemented the application, with reusability in-mind, such that it can be integrated in several performance tools. Achieved this by identifying and decoupling functionality rooted in legacy systems; streamlined the format of the results generated by reporting engines; created the data model for metadata used by the application; implemented dashboards with enhanced features to meet the latest responsive look and feel. Used Spring, JPA, Restful webservices, Angularjs, jQuery and HighCharts.
• Redesigned and developed parts of LTE performance tools to measure capacity issues, service and usage trends and their impact on various networks(LTE, Motoral, Nortel)
• Automated daily data feeders to collect data from multiple data sources; developed automation around parsing, processing, and loading information to landing zones to provide access to external clients. Developing this tool required working closely with RF domain experts and network engineers to narrow down the data process issues; helped to cleanup data within the data models ; filtered data unrelated to the reports; saved filtered data for later usage which can be used to identify and fix the network element structure data.
• Provided ongoing support in bug fixes and optimization of the performance tools.
