Hello! I am Oluwaseun Alausa, a Principal Cloud Network and DevSecOps Engineer focused on high-availability cloud networking, security, and infrastructure automation at scale.
I build and secure the core systems that other teams depend on. Multi-account architecture across AWS, advanced serverless governance with Step Functions and Lambda, and scalable GitOps infrastructure. The goal is to keep enterprise systems predictable and cost-optimised: recently designed a self-scaling GitLab CI execution plane with GitLab AutoScaler and a Docker executor, leveraging AWS Spot Instances for Worker nodes, which cut compute costs by 65%.
I enforce detective controls at scale, having deployed over 400 custom AWS Config rules using Terraform, AWS Lambda, AWS Rule Development Kit (RDK), and Python Boto3, because infrastructure stability requires adequate security and must be observable.
Master’s in Computer Science. AWS Security Specialty, AWS Developer Associate, Terraform Associate, KCNA, and AWS AI Practitioner.
Building communities matters to me as much as building the platform. I run a DevOps YouTube channel with 3.4k+ Subscribers and have published a hands-on DevOps Course on Udemy with a 4.8 rating, taken by students from 50 countries.
