Main experience:

3/2016-10/12/2018, C#.NET Software Developer, BeyondTrust, Aliso Viejo, CA 

  • Back-end: already validated all available Vulnerability Audit Backend Product use cases with exact error positions and detail reasons (thousands). No code bug found yet.
  • Front-end: Finished all eleven (11) Vulnerability OpenXML Word Reports (can be up to thousands of pages): PCI Compliance, Summary, Vulnerability Export, Regulatory Compliance, Discovery, NonCompliant, IAVA, Remediation, Access, and so on. No code bug found yet.
  • Audit Backend Syntaxes: Found and corrected several Wiki documentation errors; suggested many Wiki additions and updates; prepared a list (classification) of all use cases together.
  • TFS Source control: checking-in, merging up and down almost daily.
  • Flexible: when changed from front-end to back-end, quickly enhanced assignment-related-only skills: Vulnerability Audit Data Syntaxes, Wiki, MVC 5.0, Regular Expressions, SQL Servers, Python, Entity Frameworks, related PowerShell, C#, ASP.NET, and so on.
  • More flexible now: after completing both the back-end validation project for all available Vulnerability Audit Product use cases and the front-end project.
  • Created and made assigned HTML Reports work well with dynamic sorting (clicking a header to sort a column without any re-scan for sorting. and so on).

For example, I had “old school” HTML more than 10 years ago; in 2017, I took 6 out of 7 latest WWW html related certificate exams (HTML, CSS, JavaScript, jQuery, Bootsrap, and XML) with average score 90/100, the highest score is HTML. I skipped PHP certificate since it is unrelated to our products at all.
