WORK EXPERIENCE:

Confidential, San Jose, CA

Sr. Software Engineer

Responsibilities:

• Designed Selective Print application to conduct new print and mail claims documents process. 3-tiers design: ASP.NET MVC front-end, Claims Service Stack RESTful APIs and Claims SQL Server DB. The application allows to cut waste of paper by significant margin. It tracks pending and fulfilled orders, allows to re-print fulfilled order on demand and has potential to replace print-and-mail part of the process with print-and-secure-email with minimum effort.
• Designed Predictive Model system, which replaced existing various client risk analysis forms and services, uniformed source and output data formats as well as eliminated manual data entry when calculating client scores and premium adjustments. Multi-tiers design: 2 Service Stack RESTful APIs, Client data source, Predictive Model (DB) component.
• Designed hierarchy of physical directory structure to hold new .NET projects when converting them from Delhi, as well as projects of new development. The structure matches TFS as well as Web or App part of directory structure when deployed on IIS or as Windows Services. .NET and DB project placements as well as placements of shared libraries are standardized by intent and/or scope.
• Developed APIs and database tables and stored procedures as well as took part in front-end development of Selective Print application. Developed Claims Print Server based on Foxit Print Server Manager API.
• Developed Predictive Model services and modeling components: Actuary APIs - to initiate modeling, Bravo data access - to get client data, Vendors internal APIs - to get scores from vendors external WS (presently Valen only), and Predictive Model DB, including: tables, stored procedures, etc. to run models.
• Fixed bugs in Bravo Insurance system

Confidential, San Francisco, CA

Sr. Software Engineer

Responsibilities:

• Designed new Search 2.0 web page for Call Scape, which allowed to search for Confidential by provided values of specialized fields. In addition, designed three different types of CTN searches, which resulted in 3 separate pilot projects. All four searches generated the same result and differed only in way how search criteria was formed.
• Relevance search - keywords based, allowed to build search criteria by analyzing relevancy of words in proximity.
• Parameterized search - canonical command line approach, where option preceded expected value.
• Scope - fields search, where fields were presented as options, availability of which depended on provided content.
• Designed Call Scoring data storage to accumulate call quality data as result of evaluation of call recording, location, etc.
• Old access control of Call Scape was limited to user in single role. I created new security model supporting multi-roles, resulted in simplifying development, achieving high quality of access control and improvement of message relevance.
• Took part in redesigning Call Recording to make it HIPAA compliant. Back-end and Service Stack APIs development.
• Developed new Call Scape Search 2.0 web page and 3 pilot applications: Parameterized, Relevance and Scope searches. New search had flexibility of adding new data sources as a specialized Confidential . Both search and result pages implemented Responsive Design, and were optimized for different screen resolutions: PC browser, iPad and mobile phone.
• Implemented new security model in Call Scape. New access control made use of new custom attribute applied on each MVC Controllers’ Actions. The attribute clearly and unambiguously identified user access based on user role(s) before application thread entered Controller’s Action, and ether allowed access, threw exception or returned HTTP response of configured Response Status Code with configured message. Redesign also allowed to implement access matrix in full.
• Extended application authentication and access control flows to accept CMR user as authorized user in Call Scape. Before that, only Call Scape user was authorized. I extended the same custom attribute to distinguish user types based on origin of login. Also, I implemented handshake between CMR portal and Call Scape apps to authenticate CMR user.
• Reworked back-end of Spam/Unspam Caller Phone Number to support multiple association types of CTN. Implemented fault-tolerant flows and numerous edge-cases. Refactored and moved all business logic code into common utilities Confidential .
• Developed Test Ground branch of webpages to serve as single site for developing and testing new javascript controls and frameworks, UI widgets, ASP.NET UI controls, etc. Test Ground was also designed as online documentation site. UI controls and widgets were specific to telephony, cross-browser compatible and implemented three predefined themes.
• Created about two dozen user controls; both ASP.NET and javascript, as well as documented “How To” use them, as well as full description of available parameters, options and common examples. Here some of them:
• Context menu - configurable to show buttons, links, 2 and 3-states checkboxes as well as title and group titles on it.
• Responsive design Table - extended Footable table with sorting, filtering, server-side pagination, search criteria, etc.
• Highly configurable Highcharts based Charts control with data grid and additional panels for extra titles and data.
• Developed UI widgets: CTN, Charts and Recording Playback. Later on, CTN and Charts widgets were used by Call Scape as well as by other YP applications, which consumed Call Cloud APIs. Also well documented and with examples:
• CTN widget - UI widget to show and update CTN properties; configurable, had user role validation on front-end.
• Charts widget - specialized UI widget to draw 8 data types of Pie and Stacked Area charts and optional data tables.
• Recording Playback - based on jQuery’s jPlayer. Embeddable playback control; wav, mp3 and ogg audio streaming.
• Created about a dozen specialized javascript frameworks. Here some of them:
• Navigate Back - replacement of browser’s Navigate Back for Ember and Get/Postback/Ember mixed navigation.
• Sharing page link - configure a web page to email URL and values of required UI controls on it by single click.
• Parse CMD - specialized configurable extendable javascript framework for validating CMD commands and options.
• Rewrote Visual Provision web pages to use Google Maps instead of Bing Maps as well as CTN provision flows on them.
• Designed and developed CMD web page; similar to VT100 terminal L&F and command line style interactive behavior. Idea was to create a way to apply minimum UI development effort to access Call Cloud APIs with maximum efficiency.
• Developed Financial Report and later on refined it several times. The report consisted of complex analysis of estimated YP payments per telephone line and usage. Heavy back-end development and complex Data analysis.
