Marc W.

Certified AWS Solutions Architect/Security & Cloud Expert

Highly experienced IT professional and top-ranked AWS consultant on Upwork, specializing in AWS cloud architecture, networking, security, infrastructure, DevOps, migrations, cost optimization, AI/ML, and complex AWS troubleshooting. I'm an AWS Certified Solutions Architect and AWS Certified Security – Specialty professional with extensive experience designing, securing, optimizing, and troubleshooting AWS environments. I help organizations build secure, highly available, and cost-efficient cloud infrastructure that meets compliance requirements including HIPAA and SOC 2, supported by a small US-based team of experienced cloud and security specialists. I also bring over 15 years of enterprise IT consulting experience, including working with major investment banks in London, Sydney and New York. My work ranges from designing new AWS environments and migrating existing infrastructure to solving difficult networking, security, IAM, database and performance problems in established AWS estates. I regularly work with organizations that need senior-level AWS expertise without hiring a full-time cloud architect. Whether you're planning a migration, reviewing the security of an existing AWS environment, reducing AWS costs, implementing a complex network architecture, building an AI platform, or troubleshooting an issue your team can't solve, I can help.
