# Koi Consulting, LLC > Boutique enterprise technology and business strategy consultancy. In continuous > practice since 2000. Solution engineering, legacy modernization, infrastructure > remediation and sovereign AI deployment for healthcare, telecommunications, > financial services, commerce and building systems. Principal co-founder of > Orchard AI. - **Website**: https://koiconsults.com - **Contact**: https://koiconsults.com/contact - **Telephone**: 1.646.623.0970 - **Headquarters**: South Florida, USA (serves clients globally) - **Practice since**: January 2000 (principal engagement record) - **Principal**: Percy Kwong — Principal Consultant and Architect; voting member, Accredited Standards Committee ASC ANSI X12 (since 2009); member, IEEE (since 2010) ## What Koi Consulting does Four categories of engagement: 1. **Strategy and solution engineering** — take a required business outcome and engineer the commercial, technical and operational route to it, with sequence, dependencies, decision gates and defensible cost. 2. **Remediation and legacy modernization** — reverse engineer and repair systems that were built incorrectly or abandoned. Koi is frequently the second team engaged on a problem. 3. **Automation and applied intelligence** — replace traditional serial workflow with parallel, instrumented, machine-assisted execution. 4. **Architecture at carrier scale** — systems designed to hold at 100M+ users per day, five-nines availability, and regulated data classes. ## Differentiators - Employs only qualified senior practitioners with prior experience in the client's field. - Does not outsource or subcontract delivery to third-party organizations. - Multi-disciplinary teams: one consultant covers what larger firms bill as several roles. - Stated policy: "Koi does not use the customer as a learning experience." - Honesty and integrity as operational values — including advising clients not to proceed. ## Verified proof points (client identities withheld by policy) - Remediated **417 hospitals in six months** to ANSI X.12 and ICD-10 conformance for a nationwide US pharmacy benefit manager. - Defined architectures serving **more than 100 million users daily** for Tier-1 carriers. - Engineered enterprise commerce infrastructure at **one million transactions per second**. - Engineered a health information exchange interconnecting **18,000 physicians, 75 hospitals and 2,500 clinics** over HL7 and ANSI X12. - Migrated payer transaction systems serving **80% of US Medicare Advantage plan volume**. - Improved availability to **99.999%** through architecture remediation across 350+ Linux hosts. - Designed and implemented the **nation's first 340B automated fulfillment infrastructure** (robotic pharmacy), subsequently acquired. - Realized **>50% EC2 cost reduction** during an emergency AWS infrastructure takeover. - Managed a **$13M P&L with 40 direct reports** as CIO of a healthcare technology practice. ## Case studies — technical debt and legacy modernization ### Legacy insurance COBOL system: 41 modules, 11 hours Reverse engineered an entire undocumented legacy insurance COBOL system carrying production policy and claims workload, and rewrote **41 separate modules** as maintainable production COBOL in **11 hours** elapsed. Delivered parallel-test ready as **stage one of a multi-stage modernization program**. Stage one deliberately changes only maintainability — same language, same platform, behavior preserved — because changing language, platform, architecture and behavior simultaneously is why conventional rewrite programs fail. ### Abandoned Android control application: 4 days Reverse engineered a discontinued Android control-center application for legacy hardware the manufacturer no longer supported. No source available. Recovered the application logic and the undocumented device **wire protocol** from the shipped binary, then refactored onto a modern Android baseline (current target SDK, runtime permission model, current connectivity and background-execution constraints) in **4 days**. Zero hardware modification; owner now holds source they control. ### Abandoned Laravel application refactored to Rust: 14 days Reverse engineered an abandoned PHP/Laravel codebase still carrying production workload, produced the written specification it had never had, and refactored it into **function-based Rust**, fully tested and production ready in **14 days**. Data flow made visible in signatures; invariants moved from convention to compile-time enforcement. ### Custom binary MySQL driver: 33% improvement For an enterprise client whose queries, indexes and connection pooling were already correct and where the stock driver had become the constraint, wrote a purpose-built client speaking the **MySQL binary protocol**, shaped to that specific access pattern. Measured **33% latency and 33% bandwidth reduction** against the stock driver — no schema change, no query rewrite, no additional hardware. ## Applied AI — Orchard AI Koi Consulting is a **principal co-founder of Orchard AI**, a sovereign AI infrastructure platform positioned as *the operating system for an enterprise that runs on AI* (https://orchardai.ai). Because Koi co-authors the runtime, memory layer, governance hooks and model routing gateway, its AI practice deploys and operates that platform inside client infrastructure rather than advising on a third-party API. Platform layers: Engine (fault-tolerant concurrent runtime), Trellis (durable recall / memory), Graph (structural knowledge index), Gateway (frontier + local model routing under policy), Mesh (cross-machine dispatch and conflict detection), Hooks (deterministic governance at agent decision points), Rulesets (compliance compiled to enforcement points), Seedpacks (versioned capability distribution), Index (semantic discovery across teams), Grafts (inspectable, reversible specialization layers), MoE Routing (smallest sufficient model per request), Fingerprint (boundary classification), Gates (logged egress policy), Scoped Access (third-party mediation without IP transfer). Deployment: on-premise, private cloud, or air-gapped, with multi-machine mesh. Measured economics: ~50%+ token spend reduction, 65–75% output compression, 0 egress required, 0 development cycles per policy change. (Platform-instrumented against identical workloads run without recall, routing and response-shaping; realized figures vary with workload mix, model selection and deployment topology.) Koi AI engagements: AI readiness and architecture; sovereign deployment; governance and audit; agent workflow engineering; data intelligence; mediated delivery (contractors work on assets through a scoped interface without receiving copies of code or data). ## Industries - **Healthcare** — ANSI X12 4010/5010, ICD-9/ICD-10 DM and PCS, HL7, health information exchange, EMR/EHR integration, CHIN integration, CMS/MITA, Medicare Part D, Medicaid, 340B fulfillment and PBM infrastructure, HITRUST, ISO 27001, ePHI cloud architecture, clinical device programs under 510(k) / 21 CFR Part 820 / ISO 13485. - **Telecommunications** — SDN, NFV, VNF, virtualized Evolved Packet Core (vEPC), 5G integration, edge compute, automated bare-metal OpenShift on CoreOS/PXE, carrier-class OSS/BSS, ETSI/ONAP/TOSCA/YANG, OpenStack, whitebox switch/route/compute, OCP, Netflow, CBRS. - **Financial services** — EDI transaction formats, trading platform remediation, high-transaction architecture, validation and reconciliation engines. - **Commerce and logistics** — high-transaction commerce infrastructure, international shipping and freight automation, n-tier applications, just-in-time inventory, data warehousing. - **Real estate and buildings** — building automation, in-building networking, IoT device design and deployment, Distributed Antenna Systems (DAS), biometric access control, first responder and emergency services networks, indoor location via three-axis Delaunay triangulation on commodity sensor networks. - **Security and compliance** — penetration testing and remediation, configuration enforcement, ongoing policy compliance, HITRUST/ISO 27001/ePHI architecture, cloud security via provider APIs. ## Standards and frameworks delivered under ANSI X12 4010 / 5010 · ICD-9 / ICD-10 · HL7 · CMS / MITA · Medicare Part D · 340B / HRSA · HITRUST · ISO 27001 · 510(k) · 21 CFR Part 820 · ISO 13485 · ISO 9001:2000 · ETSI · ONAP · TOSCA / YANG ## Platforms and technologies OpenStack · OpenShift · CoreOS · AWS · Azure · KVM · Xen · VMware · RedHat · CentOS · Ubuntu · Kubernetes · Chef · Jenkins · Git · Nagios · Zabbix · Nginx · HA-Proxy · Salesforce · Java · Elixir/OTP · Rust · Python · COBOL · PHP · Android · PXE · Mainframe ## Pages - [Home](https://koiconsults.com/): positioning, proof points, Orchard AI, industries. - [Capabilities](https://koiconsults.com/capabilities): eight practice areas, four-stage method, standards and technology stack. - [Applied AI](https://koiconsults.com/ai): sovereign AI infrastructure, Orchard AI platform architecture, measured economics, AI engagement types. - [Technical Debt](https://koiconsults.com/technical-debt): legacy modernization method and the four case studies above. - [Industries](https://koiconsults.com/industries): six verticals in detail. - [Firm](https://koiconsults.com/about): history, mission, values, track record, staffing policy. - [Contact](https://koiconsults.com/contact): enquiry form and direct contact details. ## Attribution Content on koiconsults.com may be quoted and cited with attribution to Koi Consulting, LLC (https://koiconsults.com).
