Summary

01

Subhajit has spent the last two-plus years at Webskitters India developing, testing, and maintaining full-stack web applications end to end — from Eloquent models and API contracts to the Vue interfaces that consume them.

His work centers on the parts of a SaaS product that are easy to get wrong: keeping one tenant's data from ever touching another's, keeping queries fast as data grows, and keeping permissions precise enough that "admin" doesn't quietly mean "everything."
