I require a secure, semi-custom web-based platform for internal coaching use. The platform will function as a performance profiling and longitudinal tracking system used with private clients. It will: • Collect validated assessment data (baseline) • Collect weekly tracking data • Compute composite performance indices • Detect performance drift via statistical logic • Display results in a secure client dashboard • Provide coach-only analytics and alerts This is not a public SaaS product. It is a private, invitation-only coaching instrument. Security, data integrity, and clean executive-level UI are critical. ⸻ CORE FUNCTIONALITY 1. Secure Client Portal • Individual client accounts • Secure authentication (OAuth or similar) • Role-based access (Client vs Coach) • GDPR-compliant data storage (EU-hosted preferred) ⸻ 2. Baseline Assessment Module Multi-part structured assessment intake (approx. 200+ items). Requirements: • Multi-step form structure • Save progress functionality • Ability to handle large validated questionnaire batteries • Structured scoring logic (server-side) • Store raw responses and computed values separately Baseline produces: • Five domain scores (0–100 scale) • Composite index • Stored baseline reference for longitudinal comparison ⸻ 3. Weekly Tracking Module Lightweight weekly submission form (8–12 minutes completion). Includes: • Numeric inputs • Slider scales (1–10) • Short free-text reflection prompts • Timestamped entries • Auto-calculated weekly domain scores • Rolling averages (4-week moving average) ⸻ 4. Scoring & Analytics Engine (Backend Logic) Server-side logic must: • Normalise inputs • Apply weighted scoring • Compute: • Domain indices • Composite index • % delta from baseline • Z-score vs rolling mean • Implement drift classification: • Stable • Mild drift • Systemic drift • Instability • Detect cross-domain correlation patterns • Trigger internal alerts when thresholds exceeded All scoring logic must be modular and editable. ⸻ 5. Dashboard (Client View) Clean executive-style interface. Screens required: A. Overview Screen • Composite performance score • Trend arrow • 4-week moving average • Zone status indicator • Domain summary B. Domain Radar View • Radar chart showing five domains • Baseline overlay vs current • % change indicators C. Performance Trajectory • Time-series line graph • Rolling average • Visual drift shading D. Domain Detail Pages For each domain: • Current score • Delta from baseline • Volatility metric • Coach notes (visible to client) No gamification. No leaderboard. No push notifications. ⸻ 6. Coach-Only Backend View Coach dashboard must include: • Raw psychometric breakdown • Subscale access • Z-scores • Correlation matrix • Drift trigger flags • Editable client notes (private) • Manual override of interventions Client must not see internal analytics layer. ⸻ 7. Alert System When drift exceeds defined thresholds: • Internal dashboard alert • Optional email notification to coach • Client sees neutral status update (not alarmist) ⸻ TECHNICAL REQUIREMENTS Preferred architecture: Frontend: • React / [login to view URL] (or equivalent modern JS framework) Backend: • Secure relational database (PostgreSQL preferred) • Supabase or equivalent backend-as-a-service acceptable Security: • Encrypted data storage • Role-based access control • Secure authentication • GDPR-compliant hosting Analytics: • Server-side computation (not client-side) • Modular scoring logic (future adjustable weighting) Charts: • Radar chart • Line graph • Moving average • Volatility band Must be performant and scalable for 20–100 concurrent users. ⸻ NON-FUNCTIONAL REQUIREMENTS • Executive-grade minimalist UI (dark theme preferred) • No bright consumer-style UX • Professional typography • Mobile responsive • Secure export capability (PDF performance summary) ⸻ DEVELOPMENT PHASES REQUESTED Please provide quote for: Phase 1: • Core system build • Baseline intake • Weekly tracking • Scoring engine • Dashboard Phase 2 (optional, quote separately): • Wearable API integration • Advanced correlation visualisation • Automated PDF reporting ⸻ DELIVERABLES • Fully deployed secure web application • Clean source code • Database schema documentation • Scoring logic documentation • Admin documentation • Deployment instructions ⸻

This private coaching platform involves sensitive data and complex metrics, so a secure, GDPR-compliant environment with clear separation of client and coach views is key. I recently built a similar internal tool for a health coach, handling multi-step large assessments with save-progress and server-driven scoring. We used React and PostgreSQL with encrypted storage, which aligns well here. To keep the scoring logic modular, I recommend building it as a microservice or using a plugin-friendly pattern in the backend so you can easily adjust weights and drift rules later. For drift detection, do you have defined statistical thresholds or should I suggest standard deviation/baseline z-score criteria based on the data distribution? Implementing rolling averages and volatility bands can be done efficiently with server-side batch processing to keep dashboards responsive for multiple users. I also suggest defining the alert email logic with throttling to avoid overload but ensure coaches are notified promptly. The dashboard will focus on executive simplicity with clear trend visuals and minimal color—dark mode will be straightforward with styled-components or CSS variables. I’m ready to start with Phase 1 and can provide a clear timeline and breakdown to get this secure performance profiling system deployed quickly.
