Architecture diagrams, operational dashboards, and engineering plans on a work surface.

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.

Cloud Architecture

AWS, Azure, GCP, hybrid, multi-cloud, infrastructure as code, landing zones, observability, and portability planning.

AI Engineering

AI fit assessment, custom AI applications, enterprise assistants, RAG, workflow automation, model evaluation, and governance.

Security

Secure architecture, threat modeling, DevSecOps, repository protection, identity, secrets, encryption, and incident readiness.

Disaster Recovery

Business continuity, restore testing, ransomware recovery, multi-region planning, immutable backups, runbooks, RTO, and RPO.

Platform Engineering

CI/CD, developer platforms, golden paths, deployment safety, policy as code, secure build pipelines, and release automation.

Software Engineering

Custom applications, APIs, integrations, distributed systems, modernization, architecture reviews, and project rescue.

Performance

Profiling, load testing, benchmarking, latency, throughput, capacity planning, database tuning, and cost-performance decisions.

Cost Optimization

Cloud cost assessment, rightsizing, licensing, data transfer, storage, TCO, build-versus-buy, and expensive-default removal.

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.
