Welcome to the public engineering hub for Fast Dog Coding—my technical sandbox and independent consultancy. I’m Grant Lindsay, Principal Software Architect & Senior Full-Stack Developer.
This profile is a direct window into my active development, architectural patterns, and live production engines.
A live chat application that lets visitors ask an LLM about my skills and work experience, grounded in a MongoDB knowledge base and routed through OpenRouter.
- Stack: Express, EJS, MongoDB, OpenRouter.
- Core Focus: Conversational AI UX, knowledge-base prompting, session persistence, and rate-limited API delivery.

The codebase behind my official portfolio. A high-performance, ultra-minimalist web application designed with sharp, high-contrast geometry.
- Stack: Next.js, GraphQL, PostgreSQL.
- Architecture: Heavy business logic, sorting, and filtering stay in the API/backend layers so the frontend remains lightweight, predictable, and exceptionally fast.
- Live Ecosystem: 2 core public repositories running active production code (above).
- R&D & Patterns: 8 public repositories covering architectural primitives, API boilerplates, and sandbox tutorials.
- Proprietary Projects: 3 private repositories dedicated to active client infrastructure and specialized trading automation.
I build systems that value direct, clean, and highly localized execution. I prefer documented technical debt over premature, bloated systemic over-engineering, ensuring that code shipped today remains maintainable tomorrow.
