Role Cybersecurity Consultant

Team Size 3

Description: (C2C via undisclosed) As a cybersecurity consultant, IT specialist, and

software engineer, I have been engaged in an ongoing collaboration with a leading US

legal services provider, tasked with enhancing the security of their nationwide court

networks. My role encompasses a comprehensive suite of responsibilities, including

conducting thorough hardware and software audits, performing rigorous penetration

testing, and collaborating with third-party cybersecurity experts to exchange insights and

best practices. I have been instrumental in developing and executing detailed action plans

to address potential threats, crafting contingency strategies, and formulating long-term

risk mitigation approaches. My efforts have ensured the seamless execution of software

upgrades without service interruption, bolstering the security of data in transit and at

rest. On a day-to-day basis, I provide expert advice on various security concerns raised

by the network security team, ensuring the integrity and resilience of the network

infrastructure.

Initially, this partnership commenced as an intensive 40-60 hour per week engagement,

focusing primarily on cybersecurity enhancements. After the successful completion of the

initial cybersecurity objectives my involvement transitioned to a more flexible 10-40 hour

per week commitment. This adjusted schedule, primarily during evenings and weekends,

allows me to support the IT team with overflow tasks, develop custom ETL processes, and

facilitate the migration of internal tools. Additionally, I contribute to the modernization of

legacy systems, taking on roles in architecture, management, and implementation. This

ongoing relationship not only underscores my ability to adapt to evolving project needs

but also demonstrates my commitment to providing continuous support and expertise,

while maintaining the capacity to engage in parallel employment opportunities.

fulltime as a Software Engineer. Within approximately 6 months I was given the role of

Software Architect and proceeded in more wide-ranging application design and

implementation. Due to NDAs I am unable to go into many specifics on the projects I

worked on for SystemArchitecture.NET themselves and there were far too many to

mention in full, however as a high-level view of the project scopes:

Architecture, organization, and build-out of a versatile c# Windows Service to

replace legacy automation systems.

Deployment, management, and use of continuous integration environments.

Web application and portal design, implementation, and maintenance.

Legacy enterprise-scale VB6 maintenance programming.

Oracle+ArcGIS+c# applications ranging from desktop and services through web

portals in a largely SOAP-based architecture.

Windows Universal app development.

Website maintenance and design from c# and JavaScript through Wordpress.

Embedded development of handheld tablets and supporting backend database

systems.

Database design of schema, architecture, implementation, and programming

across Access, MySQL, Oracle, and Microsoft SQL servers.

Several ETL projects and database migrations at the enterprise scale requiring

extensive data analysis.

Tutoring and training of in-house and contract as well as client programmers.

Cryptographic system analysis and design.

Development support for penetration testing.

Office automation and other VBA scripting projects.

Reporting Services, and HTML/JavaScript.
