Executive Overview

Generate deterministic developer avatars as SVG via API, CLI, and web UI.

This README is written as a portfolio-grade project document: it explains the product idea, technical approach, architecture, workflows, setup process, engineering standards, and future roadmap so a reviewer can understand both the codebase and the thinking behind it.

Recruiter Quick Scan

What to look for	Why it matters
Deterministic avatar generation	Unique seed → same avatar, useful for consistent user identities
Multi-format output	SVG, JSON, QR code - flexible export options
CLI + API + Web UI	Three interfaces in one project shows full-stack thinking
Clean TypeScript architecture	Type-safe, readable codebase
Deterministic randomness	Uses seeded PRNG for reproducible outputs

Feature Depth Matrix

Layer	What reviewers should look for	Why it matters
Product	Clear user problem, target audience, and workflow	Shows product thinking beyond tutorial-level code
Interface	Screens, pages, commands, or hardware interaction points	Demonstrates how users actually experience the project
Logic	Validation, state transitions, service methods, processing flow	Proves the project can handle real use cases
Data	Local storage, database, files, APIs, or device input/output	Explains how information moves through the system
Quality	Tests, linting, setup clarity, and roadmap	Makes the project easier to trust, extend, and review

Conceptual Data / State Model

Entity / State	Purpose	Example fields or responsibilities
User input	Starts the main workflow	Form values, commands, uploaded files, device readings
Domain model	Represents the project-specific object	Transaction, note, shipment, event, avatar, prediction, song, or task
Service layer	Applies rules and coordinates actions	Validation, scoring, formatting, persistence, API calls
Storage/output	Keeps or presents the result	Database row, local cache, generated file, chart, dashboard, or device action
Feedback loop	Helps improve the next interaction	Status message, analytics, error handling, recommendations, roadmap item

Professional Differentiators

• Documentation-first presentation: A reviewer can understand the project without guessing the intent.
• Diagram-backed explanation: Architecture and workflow diagrams make the system easier to evaluate quickly.
• Real-world framing: The README describes users, outcomes, and operational flow rather than only listing files.
• Extension-ready roadmap: Future improvements are scoped so the project can keep growing cleanly.
• Portfolio alignment: The project is positioned as part of a consistent, professional GitHub portfolio.

Engineering Notes

• Separation of concerns: UI, business logic, data/services, and platform concerns are documented as separate layers.
• Scalability mindset: The project structure is ready for new screens, services, tests, and deployment improvements.
• Portfolio quality: README content is designed to communicate value before someone even opens the code.
• Maintainability: Naming, setup steps, and roadmap items make future work easier to plan and review.
• User-first framing: Features are described by the value they provide, not just the technology used.

Local Setup

# 1. Install dependencies
npm install

# 2. Start development server
npm run dev

# 3. Build or validate production output
npm run build
