We value what you've built far more than what's on your resume.

We're hiring a Python Developer in Jaipur.

Not looking for someone who can recite design patterns. Looking for someone who can open a Django codebase, figure out what's broken,

 and fix it by end of day. 3-4 years. Django / Flask / FastAPI. REST APIs. PostgreSQL. If you've maintained production code (not just built tutorial projects) — this is your role.
