<h1>About Me</h1>
<p class="sub">
<strong>Cloud & DevOps Engineer | SRE & Observability | DevSecOps | Google Professional Cloud Architect | AWS Certified DevOps Engineer – Professional</strong>
</p>
<p>
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.
</p>
<p>
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.
</p>
<p>
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.

<!-- Philosophy -->
<section>
<div class="container panel">
<div class="section-title">
<h2><i class="fas fa-seedling"></i> Trusted Architect Philosophy</h2>
</div>
<p>
I believe reliable platforms are built deliberately: clear SLOs, measurable signals, and automation that reduces toil without hiding risk. My approach fits regulated and high-throughput environments—especially fintech and data-sensitive workloads—where security, auditability, and uptime are non-negotiable.
</p>
<p>
Architecture is not only technology choices; it is how those choices affect incidents, cost, and delivery speed. I focus on resilient-by-design infrastructure, compliance-aware pipelines, and observability-first operations so teams can ship with confidence.
