What I build with

The tools, models, and infrastructure I reach for daily. Not aspirational, just what's actually in production.

AI / LLMs

  • Claude (Opus, Sonnet 4.x)

    Primary lane for planning, code review, and agent sessions. Anthropic SDK + prompt caching.

  • GPT-5 family

    Heavy execution and migrations via Codex CLI.

  • Kimi k3

    1M context for whole-repo sweeps, judging other agents' work, and mass fan-out.

  • Gemini

    Vision tasks where Gemini's perception is strongest.

  • Local models via Ollama

    gpt-oss 20B general, qwen3-coder 30B code, qwen3 4B triage, nomic-embed-text embeddings. Runs on a 48GB Mac mini, zero API spend.

Agent Frameworks & Orchestration

  • Multi-CLI orchestration

    Claude Code, Codex CLI, Kimi Code CLI, and Cursor coordinated across the estate, each on the lane it is strongest at.

  • MCP servers

    Tool protocol for code intelligence, shared memory, and semantic RAG across every CLI.

  • AgentSwarm

    Mass parallel fan-out for bulk audits, sweeps, and codegen.

  • OpenClaw

    Multi-agent swarm framework I run my personal automations on.

  • PairChat

    My own local agentic coworker. Delegated grunt work at zero API cost.

  • GitNexus

    Code knowledge graph for blast-radius analysis before any refactor.

  • Tool calling (native)

    JSON-schema tool definitions; preferred over framework abstractions when latency matters.

Frontend

  • Next.js (App Router)

    SSR, server components, server actions. This site, Huadini, blog.

  • React 18 + TypeScript

    Strict mode, no any escape hatches in product code.

  • React Native (Expo)

    Mobile clients for Expired Solutions and StylePilot.

  • Tailwind CSS + shadcn/ui

    Design system as primitives + composition. Avoiding heavy component libraries.

  • Framer Motion

    Used sparingly. Perf cost is real.

Backend & APIs

  • Python 3.11 + FastAPI

    ML inference services, agent runtimes, batch jobs.

  • Node.js + TypeScript

    Edge functions, BFFs, MCP servers.

  • PostgreSQL + pgvector

    Embeddings, RAG indexes, transactional data.

  • Firebase (Firestore + Auth)

    This site's blog, chatbot session store, Huadini auth.

  • Cosmos DB

    Expired Solutions production data store on Azure.

Infrastructure & Cloud

  • Vercel

    This site (Next.js), edge functions, OG image generation, preview deploys.

  • Azure

    Expired Solutions backend (App Service, Cosmos, Blob, ML pipelines).

  • AWS

    StylePilot (Lambda, S3, RDS). Migrated cost down 85% via right-sizing + caching.

  • Cloudflare

    DNS, edge caching, rate limiting.

  • GitHub Actions

    CI/CD, scheduled jobs, deploy gates.

  • Self-hosted CI on owned hardware

    MacBook Air + Mac mini runners for the jobs that should stay on my own machines.

ML / Computer Vision

  • OpenCV

    Pre-/post-processing for produce quality detection.

  • PyTorch

    Custom CV models (Expired Solutions produce classification).

  • Hugging Face

    Pretrained model hub. Embeddings, transcription, segmentation.

  • CLIP

    Embedding-based product/style similarity (StylePilot.ai).

  • VADER

    Fast sentiment analysis when LLM overhead isn't justified.

  • Azure ML

    Training + inference pipelines for production CV.

DevEx & Tooling

  • Claude Code

    Primary IDE-adjacent agent. This site shipped via Claude Code sessions.

  • Cursor

    Inline autocomplete + multi-file edits.

  • pnpm + Turborepo

    Monorepo + fast installs.

  • Playwright

    E2E testing on real product surfaces.

Hardware

  • Mac mini (M4 Pro, 48GB)

    Daily driver. Main dev box, local models via Ollama, always-on agents.

  • MacBook Air

    Runs the self-hosted CI runners.

  • iPhone 15 Pro

    Test device for React Native builds (TestFlight).

Agent skills

  • Skills Log

    The reusable agent skills I write and publish weekly, sanitized and open.
