Next.js Full-Stack Maintenance Expert

I run a growing web-development agency in Bengaluru and need a reliable full-stack engineer who can jump straight into an existing Next.js 15 (App Router) code-base, keep it healthy, and steadily improve it. For at least the first three to six months you will concentrate on maintaining and optimizing existing code rather than building green-field features. That means tracking down bugs, tightening database queries written with Prisma ORM against MySQL 8.0, cleaning up React 19 components, and squeezing more speed out of TailwindCSS-styled pages served behind Nginx. Time commitment starts at 10–15 hours per month; if we work well together I expect that to grow toward 40–60 hours monthly. You will work remotely and independently, but the workflow is structured—Git branches, concise pull-request descriptions, and occasional video check-ins. Initial focus areas • Bug fixing and regression testing across both frontend and backend • Performance tuning (query optimisation, bundle size reduction, caching strategies) • Light CMS support and refactors that modernise older patterns to current best practices Acceptance criteria for each ticket • All automated tests and CI checks pass • No new ESLint, type or Lighthouse errors introduced • Clear, commented commits and a short hand-over note If you are confident with Next.js 15, React 19, Prisma, MySQL, TailwindCSS and Nginx, and you enjoy polishing existing products until they shine, I’d like to hear from you.
