Independent and open source

Selected independent and open-source work.

A small collection of software whose source or public artifact can be inspected directly. Employment and client work are summarized on the resume.

Featured project

PHR · Personal Health Record

An open-source, self-hosted personal health record system for structured clinical records, source documents, DICOM medical imaging, interoperability imports and exports, and AI-assisted document extraction.

Deployment model: the source code is public and intended for self-hosting. No public hosted signup is offered.

PHR is not offered as a HIPAA-compliant service. Organizations considering regulated use must conduct their own security, privacy, and compliance assessment.

Interactive product work · Public source

Browser games

A collection of browser games sharing one application shell and authenticated cloud saves. A different kind of product work: something you can understand by playing it, with the account and persistence details still treated as engineering problems.

Rules-based computation · TypeScript and PHP

Tax-advantaged account parameters

A shared dataset of US retirement-account limits with native TypeScript and PHP engines over it. The engineering interest is consistent behaviour across two runtimes and explicit treatment of missing facts, unsupported periods, and indeterminate results.

Shared building blocks

Recurring problems that earned a reusable implementation. These support the applications above; they are not a claim that those applications are one platform.

  • genai-laravel

    Provider-agnostic generative-AI client for Laravel, with one interface that does not pretend the providers behind it are identical.

  • auth-laravel

    Shared authentication, OAuth, passkey, and account-security services. This site is one of its consumers.

  • mcp-laravel-bridge

    MCP served over an existing REST API, so tools inherit the authorization the application already enforces.

  • eloquent-privacy-policy

    An early, reviewable take on SQL-first privacy-policy enforcement for Eloquent models. Published to be read and argued with, not recommended as a production security control.
