I build, secure and run the systems businesses can't afford to lose.

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

I learned the whole board, not just one square.

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.

  • how systems are designed
  • how infrastructure is managed
  • how applications move from development to production
  • how deployment pipelines work
  • how cloud environments on AWS and Azure operate
  • how security teams think
  • how web applications are structured
  • how modern engineering teams collaborate

What I do

Four seats. One operator who can fill any of them.

01 · Application Support

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.

  • IIS
  • SQL Server
  • Microsoft 365
  • OAuth2
02 · IT Management

Lead the infrastructure and the people running it

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.

  • Infrastructure
  • Vendor & budget
  • DR / BC
  • ISO 27001
03 · Cybersecurity

Find the gap before an attacker does

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.

  • Incident response
  • VAPT
  • Hardening
  • Web app security
04 · DevOps

Ship faster, break less

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.

  • CI/CD
  • Azure
  • AWS
  • Automation

Selected work

Real problems, owned end to end.

Infrastructure · IT

Windows Server & SQL Server build on dedicated hardware

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.

  • Windows Server
  • SQL Server
  • Hardening

Security · Incident Response

WordPress malware scanner during a live breach

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.

  • PowerShell
  • Forensics
  • IR

DevOps · Automation

CI/CD pipelines with Jenkins & GitHub Actions

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.

  • Jenkins
  • GitHub Actions
  • IIS

Security · Compliance

VAPT for classification-society certification

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.

  • Acunetix
  • VAPT
  • ISO 27001

Application Support · Security

OAuth2 gateway with Azure Key Vault

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.

  • Entra ID
  • Key Vault
  • OAuth2

Infrastructure · IT

Backup & disaster recovery automation

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.

  • Rclone
  • AWS S3
  • DR

Credentials

Certified where it counts, always training beyond it.

Your move.

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.
