JAM3S is an AI-powered reputation and community system built around contribution, verification, trust and progression. I developed a working full-stack prototype using React, TypeScript, Node.js/Express and SQLite, including reputation scoring, rank progression, contribution tracking, ledger integrity checks and AI-assisted interactions. The project demonstrates product architecture, frontend and backend development, persistent data, AI integration and transparent reputation mechanics.

IRIS MiCase is an evidence-based decision-support application designed to help candidates and recruiters evaluate fit before committing. I developed the product concept, workflow and working prototype around structured evidence review, contextual evaluation and transparent decision support. The system includes candidate and recruiter experiences, case review workflows, dashboards and privacy-conscious information handling, demonstrating AI product design, full-stack application development, complex workflow architecture and human-centered decision tooling.

AMiLLiMATRiX is a modular digital ecosystem I designed and developed to connect AI-assisted applications, reputation systems, identity, evidence verification and interactive experiences within a shared architecture. The project demonstrates systems architecture, modular application design, AI integration, frontend development, data and workflow design, governance-aware engineering and the integration of independently developed services into a coherent platform.
