Situation
An insurance platform (ACA) ran on Angular 12 and Nx 13 with 12-minute build times and a 4.2s mobile LCP that hurt the user experience.
Task
Modernize the platform without stopping feature delivery and dramatically improve perceived performance.
Action
Orchestrated and executed the Angular 12→16 and Nx 13→17 migrations, optimized bundling with lazy loading, and established coding standards and code reviews across a 200k+ LOC codebase.
Result
Reduced the build from 12 to 3 minutes (75%) and LCP from 4.2s to 1.8s (57%). Sustained technical excellence contributed to extending the contract from 6 months to 2 years.
