✨ Hello, I'm
Full Stack & Backend Engineer — Python · FastAPI · Distributed Systems · AI Platforms · Cloud-Native Architecture
11+ years building high-concurrency backend systems and AI-enabled platforms — scaling a POS platform to 700+ brands, architecting multi-GB ETL pipelines, and shipping real-time WebSocket systems in production.
I'm a Principal Backend Engineer with 11+ years of experience designing and scaling distributed, cloud-native backend systems and AI-enabled platforms. I work primarily in Python, FastAPI, SQLAlchemy, Pydantic v2 and AsyncIO, building multi-tenant platforms, high-concurrency services, event-driven architectures and real-time systems on PostgreSQL, MongoDB and AWS.
Over my career I've scaled a POS platform to support 700+ brands with 60% faster load times, architected an ETL pipeline processing 1GB+ of daily data across 30+ toll plazas, and built real-time WebSocket systems handling hundreds of concurrent connections with sub-100ms latency. I also lead teams — mentoring engineers, driving code reviews, and owning system architecture end-to-end.

"Yuvraj led our POS platform rebuild with real ownership — sub-100ms WebSocket latency and zero-downtime releases became the norm on his watch."
"One of the strongest FastAPI engineers I've worked with. His code reviews consistently raised the bar for the whole team."
"Yuvraj scaled our platform to 700+ brands and cut load times by 60%. He thinks in systems, not just tickets."
Fresh notes on what I'm shipping and learning — check back often.
Rolled out a WebSocket-based live analytics module for a POS client, reducing dashboard refresh latency from 5s to under 300ms.
