PROFILE

Jiri Zbytovsky

Worked on core build and front-end improvements across web-infra-dev/rspack and trezor/trezor-suite, focusing on type safety, cross-platform reliability, and user experience. Enhanced rspack’s optimization pipeline by refining TypeScript type definitions, reducing runtime errors and improving plugin interoperability. In trezor-suite, addressed Windows-specific build failures by normalizing thread entry file paths with Node.js utilities, ensuring consistent builds. Delivered a feature to streamline device connection UX by replacing the wallet switcher with a tooltip for multi-device scenarios, while refactoring Redux selectors and TypeScript imports to resolve conflicts and restore build stability. Work emphasized maintainability, robust configuration, and reliable JavaScript and TypeScript codebases.

In August 2025, delivered two high-impact changes for trezor-suite within the trezor/trezor-suite repo, focusing on stability, UX, and maintainability. Implemented a TypeScript import stabilization effort that resolved conflicting PRs and restored reliable builds, and enhanced the device connection UX by replacing the wallet switcher with a tooltip for multi-device scenarios. These changes included targeted refactors (suite reducer and authenticity checks selectors) to fix type errors and ensure correct module resolution, as well as simplifying the device connection flow and updating tests.

Month 2025-03: Focused on stabilizing cross-platform build reliability for trezor-suite. Delivered a critical bug fix to ensure reliable generation of thread entry files on Windows by applying proper Windows path handling with Node.js path utilities. This change strengthens suite-desktop-core build robustness, reduces Windows-specific build failures, and contributes to a smoother release pipeline across platforms.

January 2025 focused on strengthening type-safety in the core optimization pipeline of rspack. Implemented a targeted bug fix to the OptimizationSplitChunksNameFunction type signature, ensuring the function receives module, chunks, and cache group key information for accurate code generation and validation. The change improves build reliability, plugin interoperability, and developer experience, while aligning with ongoing quality goals. Work tracked under issue #8707 with a single commit.
