Background

About Arthur Neves

I’m a Staff+ engineer focused on AI platforms and agentic developer products.At GitHub, I lead architecture and execution across Copilot Code Review (agentic CCR), Copilot Coding Agent integrations, and Agent HQ / Agents Platform initiatives. My role is usually the same pattern: build or shape early prototypes, define architecture, and drive cross-team execution to production.I previously served as principal technical leader for Autofix, helping take it from concept to production and establishing reusable platform capabilities (including LLM capacity optimization, caching, and rate limiting) that support multiple product surfaces across GitHub Advanced Security and Copilot workflows.Over nearly a decade at GitHub, I’ve worked at the intersection of product and platform—shipping systems that can be reused across teams, not just one-off features. I’ve also led major integration work for Dependabot and Semmle into GitHub’s architecture, with a focus on scale, reliability, and long-term platform alignment.Earlier at Shopify, I contributed to core infrastructure during hypergrowth, including database sharding work. I’m also a long-time open-source contributor, including top Rails contributions and maintaining twirp-ruby.
