Intermediate Next.js Application Benchmark Engineer

IXO is engaging specialists to evaluate complete web applications that serve as realistic software-engineering examples. Your contribution is technical work: make the reasoning inspectable, identify substantive errors and provide evidence that supports a reliable assessment.

Work you will do

• Build functional applications using Next.js, Redis and SQL, with appropriate frontend, API and database architecture.
• Implement authentication, data management, real-time behavior, reporting and business logic as the application requires.
• Use Tailwind for responsive interfaces and verify efficient data flow across the frontend, cache and database; document the design and implementation clearly.

Required background and routes

• Production proficiency in Next.js, including API routes and server rendering, Redis caching/session/realtime behavior, SQL schema/query/relationship optimization and Tailwind CSS.
• Connect frontend, cache and database layers coherently and design efficient application data flows. At least two years of relevant experience are required.

Deliverables

Submit the completed technical artifact or assessment with its supporting evidence, explicit assumptions, reproducible checks where applicable, and concise reasons for each material judgment. Address review findings within the agreed scope.
