Own the app from deploy to uptime
Deploy, integrate and support business-critical applications so users never feel the seams: ASP.NET on IIS, SQL Server databases, Microsoft 365 and OAuth2 authentication for legacy systems.

Ready to step in as your Cybersecurity Engineer
I'm Musbaudeen Oyedeji. I take business-critical systems from the server rack to the release pipeline, and I move between infrastructure, support, security and DevOps the way a good player reads the whole board.
My story
For years, I worked across different technical teams: IT support, QA engineers, product managers, developers, DevOps engineers, security engineers and network engineers.
I was never the person writing production code every day. In fact, I never was. But I was always learning. I spent years understanding how technology works beyond the code.
For more than five years, I worked in an environment built heavily around C#, ASP.NET Core, enterprise systems and cross-functional engineering teams. And I paid attention to everything. I studied how every team worked, and I learned a little from everyone.
What I do
Deploy, integrate and support business-critical applications so users never feel the seams: ASP.NET on IIS, SQL Server databases, Microsoft 365 and OAuth2 authentication for legacy systems.
Run multi-site infrastructure, vendors, budgets, disaster recovery and compliance while keeping teams and SLAs on track. Comfortable owning both the rack and the roadmap.
Incident response, server and web-app hardening, vulnerability assessment and secure configuration. I've contained live compromises and built the tooling to catch what off-the-shelf scanners missed.
CI/CD pipelines, automation, cloud on Azure and AWS, and proper secrets management: the kind of setup that makes deployments and recoveries boring in the best possible way.
Selected work
Infrastructure · IT
Stood up and hardened a production Windows Server 2022 and SQL Server environment remotely via KVM, and cut licensing costs by roughly 85% through compliant pre-owned perpetual licences.
Security · Incident Response
When a server was hijacked into a spam botnet and off-the-shelf AV missed it, I wrote a custom PowerShell scanner that detected 50+ backdoor patterns, with automated quarantine and forensic reporting.
DevOps · Automation
Automated build and deploy for application branches: Jenkins pipelines and self-hosted GitHub Actions runners pushing straight to IIS-hosted environments, cutting manual release effort and risk.
Security · Compliance
Ran a full vulnerability assessment with Acunetix to satisfy a certification-body requirement, delivering the formal report that unblocked the product's compliance sign-off.
Application Support · Security
Built an OAuth2 email gateway on Azure AD (Entra ID) to bring modern authentication to a legacy app, with all client secrets and connection strings moved into Azure Key Vault.
Infrastructure · IT
Automated off-site backups of SQL databases and application files to SharePoint and AWS S3 using Rclone, PowerShell and Task Scheduler: redundant, geographically separate recovery copies.

I'm open to Enterprise Application Support, IT Management, Cybersecurity and DevOps roles: hybrid, remote, or relocation. If you've got a system that needs to stay up and stay secure, let's talk.
