Khalid Obaide

Senior Full-Stack Engineer building large-scale cloud and AI infrastructure.

Currently at NexGenCloud, where I design and ship the platform behind a GPU cloud — inventory and orchestration systems managing 20,000+ NVIDIA GPUs, serving 1M+ monthly users on a platform generating $30M+/month.

What I work with

  • Core: Python, TypeScript, Go, C++
  • Web: Django, Next.js, React, Node.js, GraphQL
  • Infrastructure: Kubernetes, Docker, PostgreSQL, Redis, AWS/GCP, CI/CD

Selected work

  • pgchat - Chat with your PostgreSQL databases in plain English — a hardened, read-only text-to-SQL tool that generates SQL, auto-charts results, and provably never runs a write.
  • proxima - A from-scratch HNSW vector-search engine in modern C++ with Python bindings — approximate-nearest-neighbor search that benchmarks within striking distance of hnswlib, built to understand the algorithm, not just call it.
  • uplift-rag - Quantifying how much RAG actually improves LLM answers, end to end.
