Cloud Architecture
AWS, Azure, GCP, hybrid, multi-cloud, infrastructure as code, landing zones, observability, and portability planning.
Founded in 2026. Built on decades of experience.
CoreFeld
Engineering that works so well your users never notice.
We guide, design, and build cloud, AI, security, resilience, performance, and software systems using evidence, not hype, quotas, or vendor loyalty.
Guide first. Build second.
Start with the problem, not the platform.
CoreFeld helps organizations make clear technical decisions before they commit to a migration, rewrite, AI system, cloud provider, or architecture path. Paid building work should follow honest analysis.
Services
Senior engineering across the hard parts of modern systems.
AI Engineering
AI fit assessment, custom AI applications, enterprise assistants, RAG, workflow automation, model evaluation, and governance.

Technical Leadership
Fractional CTO, chief architect, technical strategy, due diligence, vendor evaluation, architecture governance, and mentoring.
Approach
Every major recommendation should survive measurement.
01
Understand
Clarify the business problem, users, constraints, risks, and success criteria.
02
Measure
Use benchmarks, cost models, threat models, failure testing, and operational review.
03
Decide
Compare realistic paths, including simpler options and doing nothing when that is best.
04
Build
Implement systems that are documented, observable, secure, testable, and operable.
Evidence-based engineering
The right technology, not the loudest technology.
We do not recommend AI when conventional software, automation, process change, or no software is the better answer.
We do not push AWS, Azure, GCP, on-premises, hybrid, or multi-cloud designs without a reason the client can inspect.
We optimize total cost, not merely the cloud bill.
Entry offers
Start with a bounded assessment.
Architecture Review
Current state, risks, options, recommended path, and roadmap.
AI Fit Assessment
Workflow analysis, data and security review, AI and non-AI options.
Security Architecture Review
Threat model, cloud/repository/CI/CD findings, and remediation plan.
DR Readiness Assessment
RTO/RPO gaps, dependency map, backup review, restore path, and runbooks.
Cost and Performance Review
Billing, architecture, performance, licensing, and TCO opportunities.
Technical Due Diligence
Architecture, delivery, security, cost, and operational risk review.
About CoreFeld
A new company with experienced judgment.
CoreFeld was founded in 2026 in Minnesota. The company is new. The experience behind it is not.
Our team brings decades of hands-on experience across multiple generations of technology. That perspective helps us distinguish durable innovation from hype.
CoreFeld is founder-led at launch and can scale through employees, trusted specialists, and subcontractors when a client problem requires more capacity or specialized expertise.
