Client had an emergency situation regarding a custom Windows .NET application that was an online store, a CRM system, an enterprise shipping/printing management system, and an employee management system.

Was able to immediately identify key security issues and attack vectors to stop ongoing attacks.

Assisted legal teams/law enforcement with chain of evidence and reports. Worked with legacy system code/server and client’s IT team to identify further weaknesses in system.

Led teams in multi-year process to modularize and replace legacy infrastructure without impacting business continuity. Upgrades included:

• Adding PCI compliance,
• Adding revision-control systems (git),
• Training staff in using git and revistion control
• Virtualization of servers, firewalls, and networks (Infrastructure as a Service)
• Haproxy over SSL for redundancy and security
• Scaling up services via virtualization and an elastic cloud for peak service times.
• Creating a full DEV(N)-TEST-PROD architecture 
• Seamless integration with hubspot (a 3rd party marketing program).
• Rebuilding client’s mobile project. Mobile Upgrades include:
  • re-coded project,
  • automated integration of mobile application into sales portal via federation (SAML).
  • Moving mobile ap from Python/MongoDB to MariaDB/PHP 
• Implementing ecommerce for digital technologies (PDFs, Video)
• Migrating from MySQL to MariaDB later.
