Tobias Järvelöv
Worked extensively on the mullvad/mullvadvpn-app repository, delivering over 200 features and numerous bug fixes across desktop and cross-platform environments. Focused on modernizing the build system, strengthening security, and enhancing user experience through robust upgrade flows, improved localization, and streamlined UI components. Leveraged TypeScript, React, and Electron to implement features such as gRPC-based management interfaces, containerized build pipelines, and automated end-to-end testing. Addressed security vulnerabilities by upgrading dependencies and tightening sandboxing. Maintained high code quality through continuous refactoring, comprehensive testing, and CI/CD improvements, resulting in a more stable, maintainable, and scalable VPN application for diverse user platforms.

Apr 1, 2026April 2026 — Mullvad VPN app (mullvadvpn-app) monthly summary focusing on delivering secure, stable, and scalable improvements with measurable business value. Key outcomes: - Security hardening and vulnerability fixes: renderer sandbox tightened by routing installer-path verification via gRPC, preventing the renderer from launching arbitrary binaries; upgraded vulnerable dependencies to CVE-fixed versions (e.g., @xmldom/xmldom CVE-2026-34601; multiple Electron-related fixes). - Core dependency upgrades: alignment for security and performance (Vite 7.3.2, Node 22.22.1, @vitejs/plugin-react 5.1.4, vite-plugin-electron 0.29.1, vitest 4.1.4). - ARM container support: added conditional ARM host handling with explicit --platform linux/amd64 to enable containers on ARM-based systems. - Location UI enhancements: improved UX with recent servers listing and prevention of unwanted auto-scroll when recents are disabled; changelog updated to reflect recents work. - Testing/CI infrastructure improvements: enhanced E2E testing environment and CI reliability; updated test runner paths; npm tooling refresh and package-lock.json adjustments (npm 11.12.1). Impact and accomplishments: - Reduced security risk and improved defense-in-depth posture, enabling safer renderer interactions and up-to-date dependencies. - Expanded platform coverage with ARM container support, broadening deployment options. - Faster, more reliable releases driven by core tooling upgrades and stabilized CI/CD pipelines. - Improved user experience in location selection and more robust testing processes. Technologies/skills demonstrated: - Security engineering (sandboxing, gRPC verification, CVE/vendor patching). - Dependency and release management (Node, Vite, Electron, npm, package-lock). - Cross-platform/containerization (ARM support). - UI/UX improvements (Location UI). - CI/CD and E2E testing discipline (test infrastructure tweaks, mocking, and workflows).
