Core923 Group is a boutique IT consulting firm. We're not trying to be the next Accenture. Every engagement gets the senior bench: principals, staff engineers, technical program leads who've shipped at Microsoft, Netflix, Salesforce, AWS, Tier-1 carriers, and Fortune 500 health systems. No bench-warming, no bait-and-switch.
We do four things differently from a Big-Four consulting firm:
The architect on your sales call is the architect on your engagement. We don't sell senior and deliver junior. If we can't field the right person, we tell you in the first conversation.
We work in your repos, your standups, your incident channels. Our engineers pair with yours. By the end of the engagement, your team owns the code and the operating discipline — we leave behind capability, not dependency.
No PoC theater. No "phase two will be the real one." Every phase ships something into production that you can take in-house if we ever part ways.
We deliberately stay small. Most engagements are 3–8 senior engineers, embedded for 6–18 months. We won't outgrow our quality bar to chase headcount.
The principles that shape every engagement.
Junior engineers add complexity to look smart. Senior engineers remove complexity to ship faster. We build systems your team can actually run on a Tuesday afternoon.
If a program is behind, we'll say so in the executive review — not in retrospect. Bad news early is cheap; bad news late is expensive.
We treat infrastructure, security controls, deployment pipelines, and detection rules as code with the same review rigor as application code. Reviewable, testable, versioned.
HIPAA, PCI, SOC 2 — these aren't policy documents. They're system properties. We engineer them in from day one so audit week becomes a sprint, not a quarter.
The best Kubernetes platform without postmortem culture will still fail. We bring the operational practices, not just the architectural diagrams.
If we can't help, we'll tell you in the first call. If a competitor would serve you better, we'll often refer you. Trust compounds; pitching erodes.
Three industries we know best — picked because they have the smallest margin for error and the highest engineering rigor.
HIPAA, HITRUST, FHIR, PHI pipelines. Hospital systems and digital-health vendors. Production engineering at clinical latency.
PCI DSS 4.0, SOX, banking platforms, payment processors. Real-time fraud, audit-grade ledgers, regulatory reporting.
5G core, OSS/BSS, real-time billing, carrier-grade observability. Tier-1 operator scale.
30-minute call. Senior architect on the line. We'll tell you on the first call whether this is a good fit.
