Delphi
Vehicle diagnostics platform for the automotive industry — migrated from a legacy system to a modern Next.js architecture, improving performance, maintainability, and scalability.
Delphi is a vehicle diagnostics and parts platform serving the automotive industry. I led the migration from a legacy monolithic frontend to a modern Next.js architecture.
The existing system was built on an aging stack with no type safety, slow build times, and a poor developer experience. The goal was to modernize the frontend while maintaining 100% feature parity and zero downtime for existing customers.
I introduced TypeScript throughout, restructured the component hierarchy for reusability, and implemented proper data-fetching patterns using Next.js App Router. Performance improved significantly — Core Web Vitals scores went from poor to good across all pages.
The result was a faster, more maintainable codebase that the team could confidently iterate on. Page load times dropped by over 40% and the build pipeline went from 8 minutes to under 2.
