## The Showcase — Ten Interactive Systems

Content integrity: these are original Brian Moreno engineering showcases running entirely on fictional, clearly non-sensitive demo data. They are not live client products and make no revenue, user-count or production-usage claims. Each demonstrates real software architecture, interface design, workflows and implementation patterns.

- Brian Moreno Operations (/work/operations) — Multi-tenant business operations SaaS: overview dashboard, customers, team, projects and tasks, approvals, invoices, reports and a full audit log, with organization switching and role-based access control.
- Nexa Market (/work/marketplace) — Multi-sided services marketplace: search and discovery with rich filters, provider profiles, availability calendars, booking simulation, favorites, messaging, reviews, and customer/provider/admin views.
- Axiom AI Workspace (/work/ai-workspace) — Production-oriented AI workspace: chat with model selection, editable system prompts, context and tools panels, agent runs with inspectable tool calls, human-in-the-loop approvals and token/cost display — fully simulated locally.
- InsightOS (/work/analytics) — Business intelligence platform: executive overview, revenue and customer trends, conversion funnel, forecasting, alerts, report builder, AI-generated summaries and a natural-language question box.
- FlowGrid (/work/automation) — Visual workflow automation builder: drag nodes onto a canvas, connect triggers, conditions, API requests, AI actions, approvals and error handlers, then run simulated executions with retries and inspect the logs.
- CommerceCore (/work/commerce) — Commerce administration platform: catalog with variants, inventory, an order state machine with fulfillment and simulated refunds, customers, discounts, abandoned carts and revenue analytics.
- CareFlow (/work/healthcare) — Healthcare operations concept: patient and provider directories, appointment scheduling, validated intake forms, notes and documents, role-specific views and a full audit history. Not a certified medical system.
- PropertyGrid (/work/real-estate) — Property discovery and operations: search with rich filters, map-style and list views, saved properties, tour scheduling, a lead pipeline CRM, mortgage estimates and side-by-side comparison.
- TalentOS (/work/talent) — Applicant tracking system: job openings, a drag-between-stages candidate pipeline, rich profiles, interview scheduling, scorecards, simulated AI candidate summaries and reporting.
- Forge Developer Cloud (/work/developer-platform) — Developer platform experience: API dashboard, key management, docs, request playground, webhooks with replay, logs, rate limits, environments, deployments, feature flags and service health.
