Yash Jain

I'm a Python backend developer with 3+ years of experience building scalable, secure, data-intensive web applications with Django, Django REST Framework and FastAPI. I design REST APIs, tune PostgreSQL and MySQL queries, run background work with Celery and Redis, and deploy on AWS with Docker and CI/CD.

Most of my recent work is on IoT platforms: telemetry pipelines, webhooks and alerting over MQTT and InfluxDB. I care about APIs that stay fast under load, and code that ships with tests.

Based in Gurugram, India.
