VirtusLab rebuilt Metals - the Scala/Java language server - from the ground up to work at a 26-million-line monorepo scale, driving weekly-active editor adoption to 92% and cutting time-to-code-intelligence to under 9 seconds.
VirtusLab helped a global technology company move critical monorepo workloads to Bazel Remote Execution with EngFlow - cutting average PR testing costs by 20% and projecting more than $3M in annual savings. Tests excluded from RBE dropped from roughly 11,000 to under 3,000, the post-merge compilation job got 3x faster, and 100% of pull requests now run on RBE.
VirtusLab migrated a leading automotive consortium's fragmented, multi-language build infrastructure to Bazel and EngFlow — cutting build times by up to 81%, reducing CI machine time by 96%, and introducing a structured human-in-the-loop AI migration framework for safety-adjacent embedded software.
Our client, an international hospitality giant, decided to move their monorepo for JVM languages (Java, Kotlin, Scala) from Gradle to Bazel. Our engineers helped complete this migration, resulting in faster build times and improved developer experience.
