PROFILE
Szymon Dziedzic
Over a three-month period, contributed to the expo/eas-cli repository by delivering seventeen new features focused on remote session management, automation, and developer experience. Work included building cross-platform remote simulator control, integrating GraphQL APIs for remote configuration, and optimizing device run session workflows. Leveraged TypeScript, Node.js, and CLI development skills to implement features such as dynamic TURN server fetching, JSON output modes for automation, and server-side validation for session duration controls. Emphasized reliability and flexibility through robust error handling, fallback mechanisms, and consistent environment management, enabling faster iteration, improved CI/CD automation, and enhanced usability for both iOS and Android development workflows.

3 Commits • 3 Features
Jun 1, 2026June 2026 (expo/eas-cli): Focused on performance, reliability, and usage control. Delivered three key features with robust fallbacks and server-side validation: Agent-Device Daemon Startup Optimization, Dynamic TURN Server Fetch for Remote Sessions, and EAS Simulator Start: Max Duration Flag. These changes reduce startup latency, improve remote session reliability, and give users explicit session duration control for paid plans. Implemented cross-checks and fallbacks to ensure sessions proceed even when auxiliary services are unavailable, and demonstrated strong TypeScript/CLI design, Bun integration, and server coordination.

May 1, 2026May 2026 (2026-05) focused on reliability, platform parity, and automation for expo/eas-cli. Key work spanned device run session lifecycle improvements, cross-platform remote sessions, API-driven remote configuration, and enhanced simulator workflows. Notable outcomes include end-to-end remote session capabilities across macOS and Android workers, a GraphQL-backed remote configuration pipeline, a Cloudflare-tunnel-based serve-sim flow, web preview URLs for previews, and machine-readable JSON outputs to streamline automation. These changes reduce operational risk, improve developer UX, and enable broader CI/CD automation with consistent behavior across platforms.
