I am a long-time open-source maintainer, published technical author, and enterprise technology leader based in Boston. For over twenty years, my work has centered on the craftsmanship of the web: establishing early front-end engineering standards, maintaining foundational open-source tooling, and architecting resilient enterprise platforms.

• HTML5 Boilerplate (@h5bp): Owner of the organization and primary maintainer across core repositories, including html5-boilerplate, create-html5-boilerplate, and main.css. (150k+ stars across the org and still shipping.)
• Front-end Developer Interview Questions: Longtime maintainer of the industry's default open-source resource for evaluating engineering talent across the stack.
• Assumptions & Constraints Manifest (ACM): Author and maintainer of the ACM specification and CLI tooling, designed to bring type-safe, auditable governance to AI-assisted code generation.
• Specialized Data Pipelines & Numeric Architecture: Building open TypeScript infrastructure, large-number/Googology tools, and schema architectures that model asset provenance, census tracking, and market velocity.

I have spent decades writing about web standards and architectural pragmatism as the platform evolved from browser wars to modern runtimes. Author of five technical titles across O'Reilly, Wiley, and Packt:

• The Uncertain Web (O'Reilly) — An architectural analysis of building resilient systems amidst platform churn.
• Mastering SVG (Packt) — Advanced, production-grade vector graphics, DOM integration, and programmatic rendering.
• Beginning HTML and CSS (Wrox/Wiley) & related core web standards titles.

Beyond the terminal, I operate Palatino Consulting, providing fractional CTO leadership, architectural modernization, and engineering governance to early-stage fintech startups, asset managers, and high-scale platforms.

Whether untangling legacy distributed systems, auditing build pipelines, or preparing codebases for institutional due diligence, I help teams balance fast execution with enterprise rigor.

• Advisory & Architecture: Navigating zero-build transitions, AI code governance, or high-throughput system bottlenecks? Reach out at rob.larsen@palatinoconsulting.com.
• H5BP & Open-Source Ideas: If you have an initiative or tool that belongs in the @h5bp ecosystem, open an issue or drop a PR.
• Craftsmanship & SVG Deep Dives: I still love getting down to the metal. If your platform has a brutal data-visualization bottleneck, complex canvas/SVG rendering challenge, or niche algorithmic problem, let's talk shop.
• Sponsorship: If you rely on H5BP or want to support independent, unpaid open-source maintenance, you can sponsor my work here.
