Software Design & Engineering

Long-term frontend support — implementation, testing, and quality — for the core business system of a commercial-vehicle leasing operator. For the multi-tenant rollout that opened the system to dealer partners, proposed and implemented a frontend design that unified tenant-specific validations, API endpoints, and response shapes behind a React Context + TenantConfig pattern. Alongside this, introduced a frontend testing strategy with Vitest and Playwright and authored implementation guides in GitHub Instructions so that the extended development team could move forward without friction.
