Hi, I'm Yuvraj Garg

AI Systems & GPU Infrastructure Engineer. Production ML, vLLM, KubeRay, LangGraph

I engineer production-scale AI infrastructure, low-latency GPU serving pipelines, and robust multi-agent orchestration systems.

I own the translation layer from research to codebases people pay for, driving model cost and cold starts down, debugging GPU memory limits when clusters break, and ensuring 99.9% reliability.

Core Engineering Values

Plan Before Coding

Draft specifications, dependencies, and baseline benchmarks first. Compare models on price, latency, and quality, never assumptions.

Manage Compute Wisely

Profile cold starts and measure hosting dollars. Actively migrating workloads off unoptimized vendors saves significant capital.

Ship Proofs Rapidly

Build operational end-to-end prototypes immediately (e.g. 12 days for budget-tracked chatbots) to validate architecture before scaling.

Own the Full Stack

Solve blockages wherever they occur, writing Streamlit/React tools, configuring API Gateways, or optimizing CDN caching to deliver results.

Projects

Systems built for scale and active usage.

Production-ready tools, self-hosted orchestrations, and cloud stacks serving real requests, not academic homework.
