The problem

Build performance, memory usage, dependencies and CI had systemic issues that slowed down the whole frontend team. I owned the initiative to find and fix them.

The approach

  • Build performance and memory: addressed the main sources of slow local builds and high memory use.
  • Dependencies: audited the packages in use and evaluated the tech stack the team relied on.
  • CI consistency: made test results consistent and stable in both local and CI environments.

The result

Local build time fell by up to 64.18%, average memory usage by about 49.15%, and vulnerabilities per audited package by roughly 42.2%. Tests behave the same locally and in CI.
