Mid Level Full-Stack Engineer

What you'll do

Each application you build becomes part of an AI training dataset. The ad asks for complete, production-quality applications, written from scratch across varied business domains, using a fixed stack: Next.js, Redis and SQL databases. Examples named are dashboards, management systems, workflow tools and data-driven platforms. Each should include user authentication, data management, real-time features, reporting and complex business logic, and together they should show different architectural patterns.

The stack is narrow on purpose. This is closer to repeatable app-building across many domains than to long-lived product work.

Who fits

• Strong Next.js, including server-side rendering and API routes
• Redis for caching, sessions and real-time data
• Solid SQL design (PostgreSQL, MySQL or similar): schemas, queries, relationships, optimization
• Ability to architect all three together, with efficient data flow between frontend, cache and database
• Tailwind CSS for responsive, utility-first interfaces
• 2 or more years of experience

What it pays

The board shows $80/hr and the ad gives no range. The listing does not publish its payment terms or weekly hours.

Worth knowing

Good:

• A well-defined stack, so you know quickly whether you fit
• Builds a varied portfolio of complete applications
• Remote contract work

Less good:

• The stack is rigid; experience in other frameworks does not substitute
• The ad title says mid level and the URL says senior; the stated bar is 2 or more years
• Payment terms and hours are not stated
• Open since October 2025, so confirm it is still taking applicants
