@vanshitajain
Backend engineer specializing in distributed systems, performance, and multi-tenant SaaS.
IndiaWhat I'm looking for
I am a backend engineer with 2.5+ years building production systems at scale, focused on distributed systems, multi-tenant architectures, and performance engineering. I have shipped high-concurrency APIs and async pipelines serving 20K+ users while maintaining zero downtime and zero incidents.
I've driven measurable impact: reduced API P95 from ~1.2s to ~240ms (5× improvement), improved classification accuracy from 61% to 91%, and raised test coverage from near-zero to 90%+ across critical booking modules. I architect fault-tolerant Celery pipelines, design identity and RBAC layers for multi-tenant platforms, and optimize DB performance with indexing and caching.
I work primarily in Python with Django/DRF and FastAPI, and I bring a pragmatic, test-first approach to shipping reliable systems—emphasizing observability, maintainability, and safe production rollouts that onboard partners with zero data leakage.
