FULL-STACK PLATFORM ENGINEERING

Constraint Modeling Platform (ECT / ACC)

React 19 + TypeScript (info site) Angular + TypeScript (methods site) .NET 10 Web API Neo4j MongoDB Node.js MCP Server

https://github.com/gcshubert/ECT-ACC

https://github.com/gcshubert/ECT

Full-stack analytical platform implementing two published research frameworks (ECT and ACC) with DOI-registered papers on OSF. Computes control-deficit analyses across scenarios accommodating values of astronomical magnitude (10^100,000+), displayed using scientific notation to avoid floating-point precision loss.

●.NET 10 multi-service REST API architecture (ECT.ACC.Api + ECT.Graph.Api) — modular domain services, graph mediation layer, Neo4j-backed parameter topology, and MongoDB document store for analysis snapshots and transformation records

●Two-frontend architecture: React 19 + TypeScript (Vite, Tailwind CSS, shadcn/ui) for the public-facing information site; Angular + TypeScript for ECT.Methods — the analytical platform with ScenarioMode-aware step tree UI, role badges, and hierarchical parameter management

●Companion to two peer-reviewed framework papers (ECT and ACC) with registered DOIs on Open Science Framework

●Built with AI-assisted engineering workflows; emphasis on clean architecture, separation of concerns, and extensibility

Resonance Mode Energy Transfer Model

Python Jupyter

https://github.com/gcshubert/Jupyter-Notebook

Computational modeling project exploring resonance-driven energy transfer dynamics.

●Parameterized simulations implemented in Python

●Reproducible experimental modeling via Jupyter

●Iterative refinement of computational experiments
