Here are your four questions answered directly: 1. WHAT SIMILAR PRODUCTS HAVE I BUILT? • NicheQuiz (https://portfolio.mcpengage.com) — A guided quiz-based platform that walks users through structured flows with progress tracking, personalized recommendations, and dynamic content rendering. Built with React/Next.js, it handles multi-step journeys with resume-where-you-left-off behavior. • CRESyncFlow — A full-stack SaaS platform (React + Node.js) for commercial real estate teams. Features an AI-powered assistant, dashboard analytics, pipeline management, and integrations with CRM systems. Production-deployed with real client data. • E-commerce platform (https://ecomport.mcpengage.com) — Full-stack storefront with admin dashboard, inventory management, and automated workflows. 2. STRUCTURED FLOWS, DASHBOARDS, PROGRESS TRACKING, AI FEATURES? Yes to all: • Built multi-phase guided journeys with milestone tracking and conditional progression • Central dashboards showing real-time metrics, completion rates, and next-step recommendations • AI assistant integration using Claude API with agentic tool loops (5 rounds per request), streaming responses, and context-aware conversations • Admin systems for content management with CRUD operations and role-based access 3. HOW DO I USE AI TOOLS TO MOVE FASTER? AI is core to my development workflow: • Claude Code for architecture decisions, code generation, debugging, and test writing • I've built a 228-tool MCP server that lets AI agents interact with production APIs — so I don't just use AI tools, I build them • Automated code review, documentation generation, and deployment scripting through AI pipelines • Typical delivery speed: MVP in 2-3 weeks, full production in 6-8 weeks 4. WHY AM I THE RIGHT FIT? • I've shipped multiple production SaaS products as a solo full-stack developer • My stack (React/Next.js + Node.js + AI integration) maps exactly to what you're building • I understand the education/gamification space — structured journeys, milestone psychology, progress visualization • I make smart MVP tradeoffs: ship the core loop fast, iterate on polish • US-based, available immediately, can start this week DELIVERABLES: • Guided journey engine with phases, milestones, and progress tracking • Central dashboard with momentum metrics • AI business coach powered by Claude API • Admin CMS for content management • Full documentation and deployment Portfolio: https://portfolio.mcpengage.com
