Overview

AfterQuery produces human-written datasets that AI labs, enterprises and startups use to sharpen their models. This role sits on the data side of that work: each application you take from empty repo to working product becomes a training example for models in development. You will lean on Next.js, Redis and a SQL database such as PostgreSQL to ship dashboards, workflow tools and data-heavy platforms for a range of business domains. The bar is production-grade software with real authentication, real data handling and real business rules, not a demo.

What You'll Do6

Take complete applications from scratch to a finished, working product that someone could run today.
Cover a spread of product shapes: dashboards, management systems, workflow tools and platforms driven by data.
Connect Next.js server-side rendering and API routes to a Redis layer and a relational store so pages stay responsive under load.
Design SQL schemas, relationships and queries that match how the application actually reads and writes data.
Add the features a given build calls for, including authentication, data management, real-time updates, reporting and complex logic.
Vary the architecture between builds so the resulting code samples cover different patterns and feature sets.

Requirements6

At least 2 years building full stack software that reached production.
Strong command of Next.js, including server-side rendering, API routes and frontend performance.
Hands-on Redis work for caching, session handling and real-time data.
Solid SQL background with PostgreSQL, MySQL or a comparable engine: schema design, joins, query tuning.
Evidence of wiring frontend, cache and database into one data flow that holds up in production.
Comfort with Tailwind CSS and utility-first styling for responsive interfaces.

Who Should Apply

A mid level engineer with two or more years of production full stack work who moves between Next.js, Redis and SQL without hand-holding. You like starting from a blank repo and finishing with something that runs, and you can shift architecture from one build to the next.

Salary Insight

The listing posts $80.00/hr with no stated weekly commitment or engagement length. For a mid level engineer working across Next.js, Redis and SQL, that rate sits above many standard contract figures for the experience band, and it generally matches people who can deliver a full application without a team around them.
