I design architectures for regulated industries that satisfy auditors, scale efficiently, and don't break the budget. Deep expertise in .NET, Node.js, and serverless on AWS.
I help engineering teams in regulated industries get senior AWS architecture help without a full-time hire. Cost optimization, compliance readiness, serverless modernization, or just a second set of eyes on your architecture.
A senior architect embedded part-time with your team. Like having a principal architect on staff without the full-time commitment.
A typical month looks like:
I'll review your AWS bill and architecture, identify 3-5 quick wins. Most clients save $5K-50K/year.
Security, scalability, and cost analysis for your AWS setup.
Move .NET or Node.js apps to serverless or containers on AWS.
I'm Dan Guisinger, a cloud architect with 20+ years building enterprise applications, most of that time in highly regulated industries like healthcare and finance where security, compliance, and auditability aren't optional.
My core expertise is .NET on AWS: serverless architectures, DynamoDB data modeling, CI/CD automation, and the cost optimization patterns that make multi-tenant SaaS viable.
Working inside large regulated organizations taught me something that pure technologists often miss: the best architecture is the one that actually gets approved and deployed. I know how to build business cases, navigate compliance requirements, and deliver incremental improvements that compound over time.
I also work with Node.js and Python teams on AWS infrastructure and architecture. The cloud patterns translate across stacks, even when the runtime doesn't. Based in Minneapolis–St. Paul, I work with companies across the U.S.
Healthcare, finance, and other regulated environments.
Architectures that pass security reviews and satisfy auditors.
I write code, review PRs, and maintain open source in production.
I understand how enterprise decisions get made.
