What I'm looking for

I seek cloud/infrastructure roles where I can lead AWS architecture, drive cost and security improvements, mentor teams, and deliver reliable, compliant systems. I seek system and back end software development roles.

I am a senior cloud and infrastructure architect with decades of hands‑on experience designing, building, and operating complex systems across AWS and on‑prem environments. I combine deep technical expertise with a consultative approach, driving migrations, compliance, cost optimization, and operational maturity.

My background spans roles as a lead architect, technical account manager, and principal systems engineer where I led multi‑account automation, PCI/HIPAA compliance projects, large data migrations, and discovery engagements that identified millions in savings. I have a track record of delivering reliable, secure, and well‑documented solutions aligned to business goals.

I have held multiple AWS and Red Hat certifications and published tools and workflows (icalPal, Bitwarden Accelerators, LastPass Accelerator, mkstack). I focus on pragmatic engineering, knowledge transfer, and building scalable, maintainable infrastructure that minimizes cost and maximizes availability.
