Professional Experience
Wells Fargo Home Mortgage, St. Louis Park, MNOct 2014/Present
Project overview: Configuration team has been writing business rules in the web application EarlyResolution (CeleritiFinTech) for several years. This application supports default-servicing portfolio: loss mitigation workflow and collections web portal. Code vendor (CeleritiFinTech) provides multiple virtual environments: production, UAT1-4 and warranty. Business logic is expanding; human mistakes occur more frequently. Configuration team needs to build several tools that would streamline business rule audit and production deployment processes. Code vendor’s backlog is large, but the team needs new tools urgently.

Application Developer (Consultant at TEKsystems)
• Administer proprietary projects for configuration team using TFS. Average project size: 5,000 LOC
• Lead software development process, manage lifecycles, provide training to team members:
o Gazelle (C#/Windows forms): compares domain logic between any two environments
o GazelleTree (WPF/XAML): converts rule table into its tree-like representation
o Tracker (C# script): daily email notifications about updates to business logic
o ArGENTum (Loan Workgroup/SPOC Re-Assignment AGENT):150,000 production loans
o Oreo (ASP.NET): user-friendly online service for constructing business scenarios (XML)
• Perform rule-based configuration in the web application EarlyResolution (ER) application
• Support SDLC by attending BRD and FSD walkthroughs to identify gaps in the requirements
• Connected configuration team to Wells Fargo’s TFS
• Conceptualized cross-environmental comparison and analysis of domain logic
• Integrated two web browser controls on Windows form
• Used OOP, event-driven programming and set theory concepts to analyze business rules
• Built web-scraping engine using HtmlAgilityPack (XPath) to process each rule table into DataTable
• Wrote LINQ expressions which return differences between two DataTable instances
• Achieved significant cuts in time/effort when comparing rules between any two ER environments
• Helped deploy rule, valid value and role task/queue permission tables to production and UAT
• Used Test Driven Development (TDD) approach during creation of new features
• Communicated with unmanaged code library (user32.dll) using DllImport attribute
• Researched PInvoke signatures that can close pop-up messages in the integrated web browser control in Windows form (ArGENTum)
• Applied extreme programming and SOLID principles to absorb changes in requirements
• Used Grid View control to display data
• Built buttons to export results into CSV and/or Excel files
• Added rule-tagging functionality
• Worked with tree, linked list, hashsets and dictionaries
• Analyzed cyclomatic and time complexities in designed algorithms
• Used logging to monitor application performance and write exception handlers
• Communicate with CeleritiFinTech about code updates to each virtual environment and web portal
• Run frequent smoke tests after each code drop to a virtual environment
• Troubleshoot defects raised by QA team during testing cycles. Use HP ALM to track all defects
• Design SQL queries to locate specific loans for system testing in MS Access database
• Use MSP system (Black Knight Financial Services) to modify loan data
• Used Attachmate.Extra library to update loan data programmatically in MSP
• Wrote Technical Approach Documentation (TAD) and user manual for each tool
• Used SharePoint to keep track of active documents
• Application retirement (ArGENTum): moved its source code to archive repository
• Decompiled existing .NET tools using ILSpy in order to perform code reviews
• Interview candidates who would take over my responsibilities in future development cycles

Starkey Hearing Technologies, Eden Prairie, MNMar 2014/Sep 2014
Project overview: Software engineering group splits into two teams – CurrentGen and NextGen.
NextGen team needs to convert existing CurrentGen codebase into its loosely coupled variation. Audiologists and existing customers would like to have efficient signal-processing logic inside hearing aids. Project manager advises to form white-box testing team that would help identify various low-level defects.

Software Engineer – Tester (White-Box)
• Collaborated with the white-box testing team in Agile-SCRUM environment
• Created series of tests using C#.NET: exhaustive, smoke, integration
• Wrote LINQ expressions to compare serialized output of parameters from hearing aids
• Test automation: developed and implemented firmware upgrade test for all types of hearing aids
• Discovered memory leak in integration branch using JetBrains (dotMemory) and perfmon
• Demoed test results to the team and release coordinator at the end of every other sprint
• Used ReSharper to analyze and refactor code
• Discovered front-end defects in company’s software application for audiologists (Starkey Inspire)
• Created email notification system that processes defect report from a nightly “UT farm” run.
Implemented .NET interoperability service to export results into MS Excel workbook
• Applied AAA methodology in my test scripts
• Tested gated check-ins in the Whitebox solution
• Used NUnit and NCrunch for testing
• Executed daily system test: installed Inspire with the latest build version, then tested hearing aids
• Participated in daily stand-ups, sprint review and sprint retrospective meetings
• Submitted conceptual design of the accent transformation technology on the Patent Day
