🎯 Auth Service MVP - 90-Day Implementation Plan

Executive Summary

Transform the Rust Security Platform into a focused Auth-as-a-Service MVP competing directly with Auth0/Okta, leveraging Rust's performance and memory safety advantages.

Target Launch Date: 90 days from start Primary Market: Startups and SMBs needing OAuth2/JWT authentication Revenue Model: SaaS ($29-$500/month tiers)

Phase 1: Foundation & Consolidation (Days 1-30)

Week 1: Architecture Simplification ⚡ Critical Priority

Workspace Consolidation

# Current: 21 Cargo.toml files → Target: 3 core crates
auth-service/     # Main service (keep)
common/           # Shared utilities (keep) 
mvp-tools/        # Essential tooling only (new)

# Archive for later (move to /enterprise folder)
policy-service/   → /enterprise/policy-service/
compliance-tools/ → /enterprise/compliance-tools/

Feature Flag Reduction

# Current: 50+ feature flags → Target: 5 essential flags
[features]
default = ["security-essential"]
security-essential = ["crypto", "rate-limiting"]
redis-sessions = ["dep:redis", "dep:deadpool-redis"]
postgres = ["dep:sqlx"]
metrics = ["dep:prometheus"]

Dependencies Audit

# Remove unused dependencies (target 30% reduction)
cargo machete                    # Find unused deps
cargo tree --duplicates         # Consolidate versions
du -sh target/                   # Measure before/after

Deliverables Week 1

  • Consolidated workspace (3 crates max)
  • Feature flags reduced to 5 essential
  • Dependencies cleaned (30% reduction)
  • Build time improved (target: <2 minutes clean build)

Week 2: Test Infrastructure Implementation 🧪 High Priority
