Oluwatosin Jegede - Platform & Cloud Architect

About Me

Cloud & DevOps Engineer | Production-Grade Platforms | SRE & DevSecOps Practices

I am a Cloud and DevOps Engineer specialising in the design, automation, and governance of production-grade cloud platforms across AWS and GCP. I build resilient systems using Terraform-driven infrastructure, Kubernetes-based service delivery, and CI/CD pipelines designed for scale, security, and operational clarity.

I integrate SRE practices such as SLIs, SLOs, error budgets, and golden-signal monitoring to improve reliability, reduce operational load, and shorten incident response cycles. I leverage AI-assisted engineering workflows, including LLM-supported design exploration, infrastructure as code, code generation, testing, security analysis, and incident investigation, to accelerate delivery while preserving correctness, security, and compliance.

My work emphasises responsible automation, observability-first design, and cost-aware decision-making, ensuring that modern cloud and AI-enabled systems remain predictable, auditable, and sustainable in regulated and high-impact environments.

Trusted Architect Philosophy

I believe that trusted architects build systems that serve enterprise demands with unwavering excellence. My approach centers on creating platforms that can handle the pressure of high-frequency trading operations while meeting the compliance requirements of enterprise fintech - because the principles of reliability, security, and scale are fundamental to business success.

Architecture isn't just about technology - it's about understanding that every system decision impacts business outcomes, whether they're financial teams processing millions in transactions or development teams deploying critical applications. I focus on building platforms that are resilient-by-design, compliant-by-default, and scalable-from-conception. Every architectural choice balances technical excellence, business viability, and operational efficiency.
