01 / PRODUCT PROBLEM
Trading data розпорошені.
Корисний trading journal не може закінчуватися таблицею перемог і поразок. Продукт поєднує structured trades з exchange exports, screenshots, якістю виконання, емоціями, journal notes, playbook rules і retrospective analysis — а потім передає цей контекст в analytics та AI-assisted review.
02 / SOLO OWNERSHIP
One product.
End-to-end ownership.
Full-Stack
21 application views, 15 API route modules, authentication, CRUD, imports, uploads and account lifecycle.
Data / PostgreSQL
Supabase schema, RLS ownership, indexes, triggers, constraints and database-level free-tier enforcement.
AI Systems
Five authenticated OpenAI workflows grounded in trades, playbooks, journal entries and emotion data.
Analytics
Performance metrics, equity curve, behavioral feedback and a 200-path Monte Carlo-style projection.
SaaS / Billing
Stripe Checkout, Customer Portal, signed webhooks and server-side AI entitlement foundations.

Interactive Monte Carlo-style performance projection на основі historical win rate та average win/loss values. Simplified projection, а не market simulator чи predictive model.
08 / PRODUCT MATURITY
Complete beta product.
Known hardening work.
Forensic audit підтвердив широку end-to-end реалізацію та визначив наступну engineering phase: schema reconciliation, сильнішу trade-domain validation, AI contracts, billing lifecycle hardening, privacy alignment, automated tests, CI/CD та operational observability.
09 / OUTCOME
Від розрізнених trading artifacts до єдиної connected product system.
AurumTrade демонструє solo end-to-end product engineering у UX, full-stack architecture, data security, analytics, AI-assisted workflows та SaaS foundations — без зведення роботи до dashboard.
