Responsible Health Tools for Real-World Conditions.
Local-first screening, clinical trial data tools, and modular electronic medical records — built with explicit data ownership, encrypted exports, offline workflows, and secure backend boundaries.
CommScreener
A screening, BIA assessment, and wellness-report prototype. Its intended use, data protection, device behavior, and deployment controls require verification before operational use.
The implementation explores React, TypeScript, IndexedDB, and a serverless backend boundary. No public claim of complete offline operation, synchronization, or production security is made without recorded test evidence.
Offline-First Sync
Patient data syncs to IndexedDB first, then seamlessly to Cloudflare D1 when online. Rate-limited financial sync runs at most twice per day per device.
Secure Admin Setup
First-run administrator registration replaces hardcoded defaults, providing robust device-independent credentials alongside existing staff sign-in.
Multi-Device Install
Fully installable PWA designed for offline preparation. Staff devices can execute screenings flawlessly without a network and sync via cloud or secure JSON backup later.
Study Design & Protocols
Structured protocol authoring with detailed intervention periods, measurement schedules, and precise participant criteria.
Trial Execution Engine
An advanced participant state machine comprehensively managing enrollment, intervention periods, data windows, and trial completion.
Simulation Lab
Powerful feasibility simulation tools strictly designed for stress-testing trial configurations prior to field deployment.
GS Trials
A constrained research prototype exploring structured study design, participant workflows, observation, analysis, and feasibility testing. Scientific validation, governance, device/offline testing, and hosted security remain required.
Built using a rigorous local-first approach — adopting IndexedDB as the primary authority for offline field data, while securing sensitive trial records with encrypted export capabilities.
GS-EMR
A modular electronic medical record specification and architecture direction. Intended use, clinical safety, terminology, consent, privacy, patient matching, and jurisdiction approval must be defined before implementation or institutional delivery.
The proposed architecture separates a browser runtime from an authoritative backend API. Security, disaster recovery, and operational controls remain requirements rather than verified production capabilities.
Browser Runtime
The primary clinical working application featuring rich offline capability, modular clinical workflows, and definitive local data authority.
Backend API
A server-authoritative API governing authentication, strict authorization, encrypted sync, audit logs, and multi-user facility coordination.
Licensing & Compliance
Licensing, security control matrices, privacy controls, and operational runbooks are required before any production-readiness claim.
Health Data Principles
Explicit Ownership
Patient and research records remain isolated in product-specific databases. No casual sharing across deployment boundaries.
Encrypted Exports
All data transfers containing identity or sensitive clinical records use strictly encrypted, versioned export/import packages.
Secure Boundaries
Multi-user authentication, authorization rules, cryptographic audit logs, and disaster recovery are universally server-authoritative.
Classification Required
Every application meticulously classifies its data, documents authority protocols, and rigorously tests offline workflows.
