Graider

Grading at the speed of a classroom

My mom is an instructor. She grades a lot of papers. I built Graider for her workflow.

We design and build end-to-end — product thinking, interface craft, and the systems underneath.

Behind the work

Screenshots coming soon

Scroll for the full case study — what we built, why, and what shipped.

Grading runs as a wizard: pick a test, upload a stack, review matches, release results.

Preview is separate from commit — teachers verify before anything touches student records.

A dedicated worker service handles the heavy lifting, with health checks and proper queue semantics.

The story

What was built, and why it holds up

The constraints, decisions, and outcomes behind the work.

The challenge

Teachers grade in stacks. Most tools assume one page at a time, which falls apart with mixed orientations, multi-page answers, and batches due before Monday.

Approach

Grading runs as a wizard: pick a test, upload a stack, review matches, release results.
Preview is separate from commit — teachers verify before anything touches student records.
A dedicated worker service handles the heavy lifting, with health checks and proper queue semantics.
Mobile capture is built for the classroom, where grading actually happens.

Outcome

Teachers see what will happen before it happens. The heavy work runs in the background, and the UI stays straight about progress.
