Charles Sieg
Architecting the future of tech

I have a consulting practice, Vantalect, through which I provide consulting services to a wide variety of Fortune 1000 clients. I specialize in cloud governance and compliance, cost-effective scalable and resilient cloud architectures, data and machine learning pipelines, and operational automation.

I started Acumen Defensive, an organization focused on cybersecurity and compliance. Acumen Defensive provides comprehensive audits of cloud infrastructure for the purposes of achieving HIPAA, GDPR, GxP, NIST, PCI-DSS, and SOC2 compliance. Acumen Defensive is also partnering to help clients reach compliance readiness for FedRAMP, StateRAMP, HITRUST, and other frameworks.

I am an expert in building scalable and highly-available infrastructure, primarily in the AWS cloud. I am highly proficient in Python, JavaScript, Golang, Swift, and C#, with particular focus on Terraform-based infrastructure automation, containerization, CI/CD pipelines, and data engineering.

I am an AWS Certified Solutions Architect - Professional and an AWS Certified DevOps Engineer - Professional. I also have several specialized certifications including Advanced Networking and Security. I participate in creating new AWS certification exams and am an authorized AWS instructor.

I am actively exploring the intersection of generative AI and software development. I write about AI coding tools, cloud architecture, and remote work as the editor of the Remote Technologist publication on Medium. I also maintain GitHub repos for the articles I write and a collection of CloudFormation and Terraform resources for provisioning AWS infrastructure.

I am the founder and president of Renkara Media Group. Renkara created AccelaStudy, an accelerated learning platform with millions of users. AccelaStudy was launched in 2008 and was one of the first 500 apps in Apple's new App Store. It has been in the App Store continually for over 15 years and serves over 30,000 student sessions every month.

At Renkara, I invented AVIAN (Adaptive Vector Intelligence and Network), a novel framework for modeling knowledge and optimizing learning performance. On October 27th, 2025, AVIAN was submitted to the United State Patent and Trademark Office as a family of 13 related patents. AVIAN is now patent pending (Application #63/906,341) and is a critical part of the upcoming AccelaStudy AI adaptive learning platform.

I design, build, and sell limited-edition furniture through Burl & Beam. I also have interest in several other startups: Apex Predictive, Verumdare, Static, and Heroic Machines.
