PROFILE

Vedran Mendelski

Vedran engineered robust CI/CD pipelines and cross-platform build systems across repositories such as status-im/status-go and status-im/status-desktop, focusing on automation, reliability, and secure release workflows. He implemented automated benchmarking, mobile library builds for Android and iOS, and enhanced code signing using Jenkins, Makefile, and Python scripting. By upgrading build environments with Nix and integrating translation freshness checks, Vedran reduced build failures and improved localization quality. His work included optimizing dependency management, introducing Discord webhook notifications for CI failures, and refining deployment logic, resulting in faster feedback loops, consistent release processes, and improved observability for both desktop and mobile development teams.

Month: 2025-10 — Implemented an automated Translation File Freshness check in the CI pipeline for status-im/status-desktop. Added a dedicated CI stage that runs make update-translations and fails the build if translation files are out of date (uncommitted changes detected), with actionable guidance on remediation. This change tightens localization quality gates, reduces drift between source and translated assets, and accelerates release readiness.
