Our Work

Real Projects Built at PK Rain Technologies, Chennai

We are not a slide-deck training institute. Every course at our Anna Nagar West centre is taught by engineers who ship production AI, cyber security and robotics systems for real clients. These are some of them — and our students build alongside us.

AI Resume Screening System

Bulk resume parsing with a human-in-the-loop correction desk.

Recruiters upload hundreds of resumes; the system extracts structured candidate data, scores fit against the job requirement, and routes low-confidence extractions to a human review screen instead of silently guessing.

  • FastAPI
  • NLP pipelines
  • PostgreSQL
  • VPS deployment

In production for an operations & maintenance services company.
