Overview

AfterQuery supplies human-built datasets that AI labs and enterprises use to fine-tune their models, and the applications you ship here feed straight into that pipeline. Each build, whether a dashboard, a workflow tool or a data platform, becomes a training example for a production-grade system. You work in Next.js alongside Redis and a SQL database, adding authentication, reporting and real-time behavior that has to hold up under real use. The stack stays constant while the business domains keep changing, so expect to shift context often.

What You'll Do8

  • Build complete applications from an empty repo through to a working product, covering the path from database schema to interface.
  • Ship dashboards, management systems, workflow tools and data-driven platforms, each carrying its own feature set and architectural shape.
  • Wire in sign-in and access control, data management, live updates, reporting and whatever business rules a given app demands.
  • Configure Redis for caching, session storage and real-time data so pages hold up under load.
  • Design SQL schemas, write queries and model the relationships between tables.
  • Compose responsive interfaces with Tailwind CSS over server-rendered Next.js routes.
  • Track data flow across frontend, cache and database, then correct the spots that slow response times.
  • Record the patterns behind each build so the example carries clear signal for model training.

Requirements8

  • Five or more years working as a software engineer.
  • Strong Next.js background, including server-side rendering and API routes.
  • Hands-on Redis work across caching, session handling and real-time data.
  • SQL depth with PostgreSQL, MySQL or a comparable system: schema design, relationships, joins and query tuning.
  • Evidence of running Next.js, Redis and SQL together in a production environment.
  • Comfort with Tailwind CSS and utility-first styling for custom, responsive interfaces.
  • Ability to trace a request from browser to cache to database and keep latency low.
  • Independence to take a blank project to a finished product without a written spec.

Who Should Apply

A senior engineer with five or more years behind them who can turn an empty repo into a working product. You know Next.js, Redis and SQL well enough to combine all three in production, and you pay attention to how data moves between them.

Salary Insight

The listing posts $140.00 per hour. That lands near the top of senior full-stack contract rates in the US market, which commonly run from $80 to $150 per hour, and it fits a candidate with five or more years of production work across Next.js, Redis and SQL.
