📊 ML Engineer Roadmap - Project Status Report

Date: November 5, 2025
Version: MVP Foundation
Status: ✅ Foundation Complete - Ready for Feature Development

🎯 Project Overview

An interactive, gamified learning platform for Machine Learning Engineers, AI Engineers, Data Scientists, and Software Engineers. Users can track their progress, take quizzes, access resources (PDFs, videos, links), and compete with their past selves through a comprehensive roadmap system.

Tech Stack:

Next.js 14 (App Router)
TypeScript (Strict Mode)
Prisma ORM
Supabase (PostgreSQL + Auth + Storage)
Tailwind CSS + shadcn/ui
Turborepo (Monorepo)

✅ Completed Components

1. Foundation & Architecture

✅ ARCHITECTURE.md - Complete system design (17 sections, 500+ lines)
✅ IMPLEMENTATION_GUIDE.md - Step-by-step completion guide
✅ README.dev.md - Developer quickstart
✅ Monorepo Structure - Turborepo with packages/apps separation

2. Database Layer

✅ Prisma Schema - Complete database models:
- User Management: users, profiles (with RBAC)
- Content Hierarchy: phase, topic, resource
- Quiz System: quiz, question, choice, quiz_attempt, quiz_answer
- User Progress: progress_item, bookmark
✅ Seed Script - Sample data (3 phases, 6 topics, resources, quizzes, users)
✅ Prisma Client - Singleton pattern with proper exports

3. Authentication & Authorization

✅ Supabase Integration - JWT-based auth
✅ Middleware - Route protection (public, protected, admin)
✅ RBAC - Role-based access control (student/admin)
✅ Auth Pages:
- Login page with redirect support
- Register page with profile creation
- Logout API endpoint
✅ Auth API Routes:
- /api/auth/login - Email/password login
- /api/auth/register - User registration
- /api/auth/logout - Session cleanup

4. Service Layer (Business Logic)

✅ ProgressService - Track user progress through topics
✅ QuizService - Quiz management and scoring
✅ BookmarkService - Save favorite topics
✅ ResourceService - Access learning materials
✅ Error Handling - AppError class with proper status codes
✅ Validators - Zod schemas for all inputs

5. Configuration & Tooling

✅ Turborepo Config - Build pipeline and caching
✅ TypeScript Config - Strict mode across workspace
✅ Tailwind Config - Design tokens and theme
✅ ESLint Config - Code quality
✅ Git Ignore - Proper ignore patterns

Phase 4: Content & UI (3-5 days)

□ Create 20+ MDX topic files (EN + TR)
□ Build reusable UI components
□ Configure next-intl for i18n
□ Add language switcher

Phase 5: Deployment (1 day)

□ Set up Supabase project
□ Configure environment variables

💡 Key Technical Decisions

1. Hybrid Content Model

Database: Metadata, structure, dynamic content
MDX Files: Long-form educational content
Why: Performance + Flexibility

2. Service Layer Pattern

All business logic in services
Never bypass service layer
Why: Maintainability + testability

3. Turborepo Monorepo

Shared packages (db, ui, config)
Independent versioning
Why: Code reuse + scalability

4. Supabase Auth

JWT-based authentication
RLS (Row Level Security)
Why: Security + simplicity
