Paylogix, LLC Westbury, NY

Senior Software Developer

September 2014-November 2021

●Senior software developer for Paylogix LLC, an employee benefit consolidation and administration service.

●Coded multiple insurance application exports. Utilized Microsoft’s Schema Definition Tool for Schema Object Model (SOM) generation. Mapped Paylogix object model to SOM through customized c# code. Xml export file generated through a single call to Microsoft’s XmlSerializer class. Task required use of asp.net, c#, sql, linq and PetaPoco.

●Developed asp.net customer service portal. Added customer service role to user authorization attributes. Many edits to asp.net buttons, JQuery dialogs and repeater controls. End user visual cues implemented through css selection of disabled elements. Performance enhancements include transfer of server side asp.net select control to client side asynchronous ajax. Additional enhancement moved frequently used datasets to local HTML5 storage.

●Provided administrative support for web and sql server relocation. Built temporary IIS web site for “Site Under Construction” web page. Consolidated and configured ip addresses on Barracuda link balancer. Other tasks included DNS registration, DMZ configuration and firewall certificate installations.

●Coded user interface for insurance application submission: System features state driven Asp.net forms sequence, Knockout javascript MVVM, Knockout Computed Observables, Observable arrays, Asynchronous ajax transmission of Pocos objects and Underscore.js for object manipulation and processing.

●Developed HIPAA 834 compliant benefit enrollment and maintenance export. Successfully passed Cigna’s X12N 5010 834 Enrollment Validation test. Reduced web server to database round trips by preloading subscription data in Pocos collections. Collections then queried with Linq for individual transaction processing. Required creation of Sql Server Server stored procedures and c# StreamWriter class. Code thoroughly tested for a seamless release. Customer emailed the following comment: “Yes, that works fine for the tiering. Thank you for making the changes so quickly. WOW! What a difference a day makes!”.

●Built Microsoft Windows Server 2012 R2 test web server. IIS 7.0 configuration included SSL certificates, Bindings and Application pools. Created Sql Server 2008 test database from production copy. Developed T-SQL stored procedure for sensitive data removal and size reduction. Added visual cue to notify end users of test environment with css styling and ninety degree text rotation. Repaired “Keys out of order on page” database consistency check with DBCC CHECKDB. Setup SSIS maintenance plan for database backup, verification and notification. Authored multiple sql server jobs.

●Added date range filtering to ftp server directory listing. Features javascript execution of Asp.net web method. Method returns an IP*Works! SSL IEnumerable collection of directory elements. Elements are then filtered with linq and sent to the browser in serialized json collection. Utilized knockout extender for data entry validation. Added csv export capability through execution of an .ashx generic handler. Handler launches Excel spreadsheet by returning mime type “application content”.

●Migrated customer facing websites from asp.net 2 to 4. Asp.net’s updated request validation required addition of client side javascript to escape fields populated by TinyMce WYSIWYG editor. An alternate solution might have been to turn off Asp.net 4’s updated validation, however that would have increased the surface area available for cross-site scripting (XSS) attacks. Each web site’s application pool was reconfigured to run .net framework 4.0 and each web.config required manual edits.

●Debugged federated identity authentication issue. ComponentSpace SAML v2.0 provides federated identity api for cross domain logins. Browser session launched in IFrame through Paylogix hosted .ashx generic handler. Generic handler populates user identification and enrollment data in transmittal attributes. Messages signed with x.509 certificate and sent to the service provider through http post SAML binding.

●Developed web based credit card payment application. Network Merchants, LLC (nmi.com) Three Step Redirect API™ provided secure data transmission and stored sensitive payment information. knockoutJs provides client side infrastructure for a pageable statement grid. View Model transmitted to client in Json and stored in IIS session variable for post back validations. Bootstrap framework provided styling for phones, tablets and desktops. Android, Windows Phone, iPhone and iPad tested with BrowserStack (www.browserstack.com). Tables styled with table-responsive class providing horizontal scrolling on iPhone devices. Transactional integrity implemented through use of Microsoft’s SqlTransaction object. Credit card integrity check provided by JQuery Validation Plugin (http://jqueryvalidation.org/).

●Coded six exports for Bill and Melinda Gates Foundation. Export data formats include Ansi 834, comma delimited text and xml. Datatable written to serialized data stream using Microsoft’s System.Xml.Linq class. XML elements created with XElement Constructor and added to xml data stream with Add method.Utilized Linq’s concatenation method to group results from multiple SQL stored procedure calls. Required extensive coordinated testing between multiple organizations.

●Utilized Boston Mutual’s web bridge api for benefit enrollment. Object model created by adding Web Service Definition file to Visual Studio 2013’s web references. Paylogix business layer updated to include multiple active tiered subscriptions, requiring changes in T-SQL stored procedures and Linq. Customer enrollment data entered through Paylogix hosted iframe sourced to Boston Mutual’s website. Boston Mutual then executed predefined callbacks to update subscription data in the Paylogix database. Dynamic enrollment configuration parameters created using Code Project’s Fast Lightweight Expression Evaluation Control, allowing formulas containing dynamically compiled c# to be embedded in configuration data.

●Coded csv file export for insurance provider. Added DataRowExtensions class to strongly type pre-existing .net datatables. Same tables Linq enabled through addition of AsEnumerable method. Participant Age Band definitions implemented using c# collection initializers. Csv data assembled in C# StringBuilder object and later presented by StreamWriter object.

●Converted Classic ASP pages to .Net. Data access Adodb recordsets converted to PetaPoco and Linq. Task required line by line analysis and modification of existing inline vb.net server tags. T-SQL performance enhancement converted row based raw t-sql column queries to left joins. Enhancements extensively tested.

●Coded Ansi 834 benefit enrollment export for BlueCross BlueShield. Built reusable object library using Gang of Four (GOF) factory pattern. Dependency Inversion Principle implemented by parameterization of factory object with organization and provider keys. Keys queried during object creation to compose unique 834 document implementations.

●Coded TLS 1.2 security enhancement. Microsoft System .NET transport layer replaced with Nsoftware IPWorks SSL. Task necessitated due to Windows 2008 server lacking native TLS 1.2. Code utilizes GOF (“Gang Of Four”) singleton pattern for shared transport instances across multiple asp.net web pages. C# lock keyword protected critical sections of code during singleton instantiation. Server SSL certificates verified in code through registration of event handler delegate.
