Frontend engineer, open-source maintainer, and product builder.
I build developer tools, AI-assisted workflows, local-first apps, and practical resources through David Dias Digital.
I'm David Dias (he/him), a French-born 🇫🇷 Canadian 🇨🇦 with Portuguese 🇵🇹 heritage living in Toronto, Canada.
For 15+ years, I have worked across frontend architecture, accessibility, design systems, developer experience, and product engineering. My work tends to live where craft matters: interfaces people use repeatedly, tools developers depend on, and systems that need to stay understandable as they grow.

- Make quality operational. Good frontend work needs repeatable systems, not heroic cleanup at the end.
- Design for real workflows. I care about dense, useful interfaces that stay calm under repeated use.
- Respect accessibility, privacy, and maintainability. These are product decisions, not checkboxes.
- Build for humans and agents. Documentation, MCP surfaces, tests, and structured rules make software easier to inspect and improve.
