Context

The challenge

Making high-volume review fast and workable.

The platform had to keep application review, interviews, and administration workable for more than 1,000 applicants and more than 50 interviewers. That meant the data path and the reviewer interface both had to support a high-volume recruitment workflow.

Krishang's role

  • Collaborated within a 50-plus-person team on the applications portal.
  • Optimized the CockroachDB schema and Redis caching path.
  • Built the browser-like reviewer workspace and an App Router administration dashboard with Server Actions, Prisma, and PostHog.

Choices

Engineering decisions

What shaped the build.

01

Design around reviewer context

The reviewer surface uses tabs and browser-like multitasking to keep several application tasks within one workspace.

02

Optimize the shared data path

Schema work and Redis caching targeted the query path used across the recruitment workflow.

03

Keep administration in the same web stack

The admin dashboard uses App Router, Server Actions, and Prisma rather than introducing a separate administration application.
