> SYSTEM_OVERVIEW

Mayko Reports is an internal Single Page Application (SPA) serving as the operational heart of a performance marketing agency. It solves the problem of data fragmentation by aggregating SEO, Google Ads, and time-tracking data into a single source of truth. The system offers real-time profitability analysis (ROS), automated client reporting, and AI-driven insights, replacing dozens of disconnected spreadsheets.

Core Architectures

Multi-Channel Aggregation

Normalizes data from disparate ecosystems: SEO (GSC, GA4), Performance (Ads, TikTok, Meta), and Work Logs (Teamwork API). It creates a unified view of agency health.

Profitability Engine

The core financial module. It calculates 'Burn Rate' and Margin in real-time, factoring in dynamic employee hourly rates, fixed costs (links), and media spend.

AI Analysis (GPT-4o)

Automated intelligence that cleans raw work logs for client reports, detects 'Content Decay' in SEO data, and writes narrative summaries of monthly performance.

Security & RBAC

Enterprise-grade security. Row Level Security (RLS) ensures users only see their projects. Role-based access (Admin, Specialist, Client) is mapped automatically via API.

ERR_01

Token Rotation & Session Continuity

Google OAuth tokens expire every hour. Implemented a 'Silent Refresh' strategy using Supabase and serverless functions to maintain uninterrupted sessions without forcing user re-login.

ERR_02

Performance at Scale

Fetching history for 50+ projects caused bottlenecks. Solved via JSONB Caching in Supabase and 'Optimistic UI' updates, giving users instant feedback while data syncs in the background.

ERR_03

Client-Side Security

To protect API keys in a client-side Vite app, all sensitive operations (token exchange, payment logic) were moved to serverless edge functions, protected by strict RLS policies.
