Vue 3 & Nuxt
Loved Vue's single-file components and reactive primitives, but professional work favored React.
Next.js (App Router)
Platform lock-in around Vercel primitives, complex server action edge cases, and opaque caching rules. Shifted to Astro for content and Vite + TanStack for rich client apps.
iTerm2 & Alacritty
Alacritty was fast but lacked native macOS tabs; iTerm2 was feature-rich but felt heavy during high-throughput stdout. Ghostty solved both with GPU speed and native Cocoa tabs.
Cursor
Inline completions were useful, but Cursor's full-codebase indexing, multi-file agent diffs, and instant composer edits leapfrogged traditional single-line completions.
Poetry & pyenv
Slow lockfile resolution and brittle python version shims. uv resolves dependencies in milliseconds and manages isolated Python versions natively in Rust.
PostgreSQL + Prisma
Connection pooling overhead, heavy Docker containers for local dev, and Prisma's query engine binary. Turso + Drizzle offers instant edge libSQL with zero cold starts.
Node.js + pnpm
Managing separate runtimes, tsx loaders, vitest, and package managers created friction. Bun bundles runtime, package manager, and test runner into a single fast binary.
Zsh + Oh-My-Zsh
Bloated plugin setups caused noticeable startup lag on new shell windows. Fish provides instant out-of-the-box autosuggestions with zero configuration lag.
Notion
Cloud lock-in, slow electron startup, and offline unreliability. Obsidian keeps architecture decision records and notes in plain local markdown that I own forever.
Docker Desktop
Excessive background memory consumption and battery drain on macOS. Colima runs containers via lightweight Lima VMs using native Apple Virtualization.
Alfred
Alfred was solid for years, but Raycast's React-based extensions ecosystem, built-in window manager, and developer tooling integrations are far more capable.
Raw Claude & ChatGPT Web UI
Copy-pasting code into web chat tabs lost context and couldn't run tests or inspect files. Local agent harnesses with tool execution and skills keep the feedback loop local.
Microsoft Azure
Used it at an earlier org for enterprise VNET workloads and Azure OpenAI endpoints; current work has standardized on AWS.
Tooling philosophy
Fast feedback loops, low memory pressure, plain-text configuration, and zero lock-in. When a tool stops paying for its complexity, it moves to the graveyard.
