**Developer Advocate at GitHub**

Scaling developer experiences to 150M+ engineers worldwide

**Focus Areas:** Developer communities • Customer success • Open source • Enterprise scale

## About Me

**Transforming how enterprise teams adopt and scale developer technologies.** As a Senior Developer Advocate at GitHub, I bridge the gap between cutting-edge tools and real-world implementation, helping organizations unlock the full potential of their development workflows.

### Impact Metrics

- **100M+** Developers Reached
- **10+** Years Experience
- **100+** Speaking Engagements

My decade-plus journey in developer tools encompasses everything from Git workflows and DevOps practices to AI-assisted development. I specialize in translating complex technical concepts into actionable strategies that drive measurable business outcomes—whether that's reducing deployment times, improving security posture, or accelerating time-to-market.

### What sets me apart

My unconventional path from Army service and construction management to software engineering gives me a unique perspective on practical problem-solving. I understand both the technical challenges and the human dynamics that make or break technology adoption in large organizations.

Beyond client work, I'm an active voice in the developer community through conference speaking, technical writing, and creating open source developer tools. I've built projects like Team X-Ray, a VS Code extension that helps developers understand team expertise and collaboration patterns. I believe the best advocacy comes from real-world experience, which is why I stay hands-on with the tools and practices I recommend.

*Based in Florida with my Welsh partner, two sons, and two dogs. When I'm not advocating for better developer experiences, you'll find me mentoring emerging talent and contributing to the open source projects that power our industry.*

## Featured Projects

Open source tools I've created to solve real developer problems and enhance team collaboration.

### Agent Context System

*Context engineering fundamentals for AI coding agents*

**Status:** Open Source

Two markdown files that give every AI coding agent — and every subagent — shared project knowledge and session-to-session memory. AGENTS.md is your project's committed source of truth, always in the agent's prompt. .agents.local.md is your personal scratchpad, gitignored, growing as the agent logs what it learns. No plugins, no infrastructure — just files that work across every major coding agent.

**Key Features:**

- Cross-platform: works with Cursor, Copilot, Codex, Windsurf, Factory, and Claude Code
- Session-to-session memory via gitignored scratchpad that agents update automatically
- Instruction budget discipline — root file stays under 120 lines for optimal agent compliance
- Knowledge promotion pathway from personal scratchpad to shared project context
- Subagent-aware design — shared context for parallel agents that don't inherit conversation history

**Technologies:** Markdown, Bash, Context Engineering, Shell Scripts, Cross-Platform Agents

- Live Demo: https://agents.mainbranch.dev/

### Team X-Ray

*Stop being a stranger on your own team*

**Status:** Open Source

A VS Code extension that reveals team expertise through code analysis. Discover the humans behind your codebase, reveal hidden expertise, and understand how your teammates collaborate.

**Key Features:**

- File expert discovery by right-clicking files
- AI-powered team expertise overview
- Smart challenge matching to identify team members' strengths
- Integration with GitHub's Model Context Protocol (MCP)

**Technologies:** TypeScript, VS Code Extension, GitHub Models API, Git Analysis

**Links:**
- GitHub: https://github.com/AndreaGriffiths11/teamxray
- VS Code Marketplace: https://marketplace.visualstudio.com/items?itemName=AndreaGriffiths.teamxray

### Git History Cleaner

*Safe git history management made simple*

**Status:** Open Source

A web-based tool that helps developers generate customized bash scripts for clearing Git repository history while preserving current files. Features a user-friendly interface with built-in safety checks, automatic backup creation, and plain English explanations for each Git command.

**Key Features:**

- Safe script generation with automatic backup commands
- Plain English explanations for each Git operation
- Multiple output formats: clipboard copy, .sh download, inline viewing
- Input validation and repository name sanitization
- Customizable branch names and safety options
- Educational UX that emphasizes user responsibility

**Technologies:** React, TypeScript, Vite, Tailwind CSS, Radix UI

**Links:**
- GitHub: https://github.com/AndreaGriffiths11/git-history-cleaner
- Live Demo: https://andreagriffiths11.github.io/git-history-cleaner/

### Open Source Best Practices

*A comprehensive framework for launching and hardening sustainable open source projects*

**Status:** Open Source

An 8-phase framework designed for developers preparing projects for public release or improving existing repositories. Covers security (git history cleaning), legal and ownership, community governance, documentation, infrastructure setup, maintainer expectations, vulnerability reporting, and funding sustainability.

**Key Features:**

- 8-phase launch framework from security audit to funding sustainability
- File checklists for LICENSE, CONTRIBUTING, CODE_OF_CONDUCT, and SECURITY.md
- Governance structures and maintainer role definitions
- GitHub Sponsors setup and funding sustainability guidance
- Compatible with GitHub Copilot, Claude, and agentic AI workflows

**Technologies:** Markdown, Open Source, GitHub Actions, CI/CD, GitHub Sponsors
