    "summary": "Backend engineer with 10+ years of experience across startups and scale-ups–greenfield builds, legacy migrations, developer tooling, and cross-team delivery. From Android and Rails to Elixir and now Rust, I’ve consistently adapted to new stacks and owned features end-to-end. I thrive where clarity, autonomy, and system thinking matter more than hype. I’ve scaled platforms to 20M+ monthly bookings, spoken at conferences, contributed to open source, and led engineering initiatives from CI pipelines to observability rollouts. Currently focused on Rust–building tools, systems, and AI agents–looking to join a team solving real technical problems with modern systems.",
