About

Builders, not a research lab.

MetisMesh is a small firm with a long memory. The person you talk to is the person who designs the system, writes a good share of the code, and answers when it pages at two in the morning.

The founder's story

In 2000 the plan was months of manual rework: six hundred screens of a Medicaid client to be reproduced by hand in a new architecture. I built a code generator instead. Schemas and metadata in, consistent data access, controllers and templates out. It became a reusable company asset and won an award, but the lesson mattered more than the trophy.

The first version was rough. I rebuilt it after watching it run. The second was leaner. That has been the discipline for nearly three decades across enterprise Java, federal modernization, cloud platforms and integration: do not solve the immediate task, solve the class of problem, then refine it on real feedback.

When I started building retrieval systems and agentic workflows, the same failure modes were everywhere. Remarkable models inside weak systems: no architecture, no provenance, no plan for the day the model is slower or wrong. Meanwhile the correctness-critical parts of the business, the calculations, the approvals, the money, were being handed to something probabilistic because it was fashionable.

MetisMesh is the result. Since June 2025 I have split my time between consulting engagements and products I design, build and operate myself. The consulting work spans a treasury knowledge system on Google Cloud, a controlled multimodal review platform in AWS GovCloud, an oncology knowledge assistant on Bedrock, and a provider-search agent integration in healthcare. The products are the six on this site. Both kinds of work keep me close to the whole system: the business problem, the data model, the security boundary, the implementation, the deploy, and what it costs to run.

We do not catch fish for people. We teach them to fish, and we leave behind something that keeps working after we have gone.

The arc

Twenty-eight years of building, four chapters.

Every chapter is hands-on. Architecture that stayed close to the code, and problems that only got harder.

  1. 2025 to present

    MetisMesh

    Principal Architect, Lead AI and Software Engineer

    Commercial consulting alongside products designed, built and operated in-house. Retrieval and agentic systems for a treasury knowledge base on GCP, a controlled multimodal architecture-review platform in AWS GovCloud, an oncology knowledge assistant on Bedrock, and a provider-search agent integration in healthcare, plus the six products on this site.

  2. 2015 to 2025

    DXC Technology

    Associate Partner, Cloud and Enterprise Architect

    Hands-on architecture across modernization, analytics, integration and platform programs: a KPI analytics platform on Azure in Go, an AWS microservices platform for bank integrations, federal modernization on Grants.gov under FedRAMP and FISMA, vehicle telemetry integration for LA Metro, operational services for New York MTA, legacy COBOL-derived Java brought from hours to minutes for Daito, and a metadata-driven partner integration layer for Mastercard.

  3. 2006 to 2015

    RIZ Consulting

    Senior Solutions Architect

    Federal modernization for EPA, VA, USDA and Grants.gov: secure Java mission systems, rules engines for benefits and claims, and developer tooling including a static-analysis tool that caught resource leaks and injection risks before they reached testing.

  4. 1997 to 2006

    CSC Consulting

    Senior Architect

    Large modernization and integration programs across financial services, telecom, retail, healthcare and assessment during the industry's move from client-server to enterprise Java. Built Codester, a metadata-driven generator that carried a 600-screen Medicaid migration and earned a Technical Excellence Award.

What we believe

Short, because it has to survive contact with a deadline.

  • Production first

    A system is finished when it is running well, not when the demo works.

  • Evidence over adjectives

    Every claim beside a real project, a real number or a real era of work.

  • Rules decide, intelligence proposes

    Correctness-critical logic stays deterministic. AI helps inside it.

  • Enablement, not dependency

    You should be able to run, change and extend what we build without us.
