Hi, I'm Mariano 👋🏻

Software Developer with 5+ years building web products from UI to infrastructure.
Currently at A-SAFE Digital, working full-stack in a Rails + React monorepo.

Outside work I build and maintain open source, most of it circling the same question: what does day-to-day development actually look like when AI is part of the toolchain and human judgment still owns the architecture?

What your sponsorship maintains

  • Reactive Contracts - bidirectional API contracts that put the frontend in control: compiler, RPC layer and validation.
  • Auto Claude - a small, auditable bash loop that runs Claude Code unattended against a queue of tasks, gated by a verification command.
  • AI Workbench - a frontend-first AI engineering lab: streaming chat, tool calling, human-in-the-loop approvals, structured outputs, LLM observability and code-based evals.
  • WebMCP Lab - reference demos and eval fixtures for WebMCP, the proposed standard for exposing page tools to in-browser agents.
  • TopoJS, Formachine, Ollama TUI, Freelow, Create Stack, Liquid Glass - the smaller libraries and CLIs I keep releasing and supporting.

I also contribute upstream, where the leverage is highest: PixiJS, shadcn/ui, pmndrs/drei, react-email, Radix UI, Next.js docs, unavatar.

Why sponsor

Building the first version is the fun part. What sponsorship pays for is the rest: issues, releases, docs, dependency bumps, answering "does this work with X?" — plus writing up what I learn at marianoalvarez.dev instead of leaving it in private notes.

No tier gates anything. Every project stays open source and free to use; sponsoring just means the maintenance gets real hours.

Thanks for reading this far. ❤️
