What I'm looking for

I’m looking for a hands-on AWS Cloud Architect role where I can lead cross-functional delivery, build secure multi-account platforms, and use automation and Secure-by-Design to improve resilience, scalability, and cost—then partner closely with security and stakeholders.

I’m a CloudArchitect with 10+ years of software engineering experience, including 4+ years designing enterprise AWS platforms for Global Pharma and Fortune 500 clients. I design multi-account AWS architectures that balance resilience, scalability, and cost optimization.

I lead cross-functional teams while staying hands-on in architecture, technical design, implementation, and stakeholder communication. I integrate security and compliance through Secure-by-Design practices, IAM governance, encryption, and risk reviews in regulated environments.

Across regulated and high-traffic environments, I build event-driven and serverless systems, platform integrations, and infrastructure automation using Infrastructure as Code. I embed automated security checks and data-protection guardrails into Terraform and CI/CD workflows to reduce production defects and accelerate delivery.

I hold all active AWS certifications and am an AWS Golden Jacket holder. I combine deep AWS expertise with an MBA perspective to align architecture decisions with delivery, cost, and business priorities.
