Hi, I'm Huy

I'm a senior full-stack software engineer building realtime and AI products end to end — from Django/FastAPI backends and React frontends to Kubernetes infrastructure — and the author of open source libraries like chanx, fast-channels, nplus1, and drf-auth-kit. This blog is where I write about what I learn along the way.

• Python API Framework Benchmark: FastAPI vs Litestar vs DRF vs Django Ninja vs Django Bolt - Real Database Queries and JWT Cookie Auth

  9 Aug, 2026

  Ten framework and server configs benchmarked on real PostgreSQL workloads and JWT httpOnly cookie authentication. The 37x JSON gap collapses to 1.8x on authenticated queries, auth itself costs about 10%, and tail latency reorders the leaderboard completely.

• Streaming Agents with Pydantic AI over Typed WebSockets: Tools, Approvals, and a Generated Client

  6 Aug, 2026

  Building a production-style AI agent server with Pydantic AI + FastAPI + chanx: streaming structured output and human-in-the-loop tool approvals over a typed WebSocket contract, background runs broadcast to conversation groups (multi-tab, refresh-proof, approve from any device), AsyncAPI-generated TypeScript clients, and offline tests without an LLM.

• Schema-First API Development with DRF + React: OpenAPI as the Contract

  11 Jul, 2026

  How my team ships DRF + React features without ever hitting a mistyped param or outdated API call: drf-spectacular as the source of truth, generated zod clients, auto-generated forms, and strict typing on both sides.

• Python API Framework Benchmark: FastAPI vs Django vs Litestar on Real Database Workloads

  23 Jan, 2026

  I benchmarked the major Python web frameworks against real PostgreSQL workloads. The 20x performance gap you see in JSON benchmarks collapses to 1.3x once the database gets involved.

• ChanX: Structured, Type-Safe WebSockets for Django and FastAPI

  10 Oct, 2025

  A batteries-included WebSocket framework: automatic message routing with Pydantic, mypy/pyright type safety, auto-generated AsyncAPI docs, and testing utilities — one codebase for Django Channels and FastAPI.
