Sibylline Internal Tools, Automation, and Security
Built public and internal web tools, analyst data interfaces, Microsoft 365 administration, endpoint policies, workflow automation, and employee security training for a remote intelligence organization.
- Role
- Technical Developer
- Context
- Web development, internal tools, Microsoft administration, and security.
Challenge
The organization needed custom web development and analyst tools alongside reliable remote-work administration and security. Those needs overlapped: onboarding affected identities and devices, analyst tools depended on accessible data, and security controls had to fit how employees worked.
My role
My responsibilities expanded from frontend development into full-stack tools, Microsoft 365 and Intune administration, Power Platform automation, and employee security operations.
Constraints
The work supported remote staff, analyst delivery, device and application management, and ongoing security needs in an established Microsoft environment. Each change had to fit the way employees already worked.
What I changed
- Built and maintained the company's public website and supporting web infrastructure.
- Developed a MERN application for filtering, mapping, and exporting UK crime data.
- Created responsive interfaces for internal tools.
- Designed and rolled out Microsoft Intune policies for device and application management.
- Built Power Platform apps and automations for onboarding, offboarding, and office processes.
- Ran phishing simulations and developed employee security training.
- Administered Microsoft 365, Entra ID, Intune, SharePoint, Teams, Exchange, and related Azure services.
Key decision
I used the platform that fit each problem: custom MERN applications for specialized data tools, Intune and Entra ID for device and identity policy, and Power Platform for business-process automation.
Results
- Gave analysts an interactive way to filter, map, and export UK crime data.
- Standardized parts of onboarding and offboarding through reusable automation.
- Expanded device and application policy management for remote staff.
- Established repeatable phishing simulations and employee security training.
What I learned
This role taught me to treat software, administration, and security as parts of the same employee and analyst experience instead of isolated technical responsibilities.
