The business challenge
As the product grew, new features kept shipping, but each one seemed to take longer than the last. Different parts of the application had implemented similar logic in slightly different ways, folder structures varied by feature, and there was no single source of truth for how API calls or TypeScript models should be written. The team wasn't lacking talent; they were fighting inconsistency that compounded with every new feature.
The approach & technical solution
I worked through the codebase systematically, refactoring shared UI components into one reusable set rather than several near-duplicates, and introducing a consistent folder structure and shared utilities that new features could build on instead of reinventing. API communication was centralized into a single layer instead of being scattered across components, and TypeScript models were standardized so the same data shape wasn't defined three different ways in three different files. Deployment workflows and environment configuration were also cleaned up, reducing manual steps and inconsistencies between environments.
Business outcome
The cleaner architecture reduced duplicated logic across the application and gave the team a consistent pattern to follow for new features, shortening the gap between starting a feature and shipping it. Just as importantly, it made the codebase easier for other engineers to onboard into, since the same conventions applied everywhere instead of varying feature by feature.
