👋 Hi, I'm Bob

Senior Full Stack Software Engineer

I build performant, serverless, cloud based web applications with conversational AI features like LLM chat assistants and tool calling, using TypeScript, React/Vue, Node, PostgreSQL, and AWS, working AI-first with Claude Code and spec-driven development.

How I Build

An AI-first workflow: every change starts as a spec, gets its tests first, and ships as a vertical slice built with Claude Code.
  1. 1. Write the spec
    Write the change as an OpenSpec proposal, so the requirements are agreed before any code exists.
  2. 2. Write the tests
    Turn the spec into failing tests, then write the code that makes them pass with test driven development.
  3. 3. Build with AI
    Implement one vertical slice at a time in its own git worktree, driven by Claude Code skills and agents.
  4. 4. Review and ship
    Check every change against its spec, with lint, typecheck, and tests gating CI in GitHub Actions.

AI Storefront
AI Chat AssistantOpenAI LLM
An AI shopping assistant that searches the catalogue, suggests cart changes, and drafts an order for you, though it never places one. The storefront around it is a full stack e-commerce template with search, promo codes, store-wide sales, digital products, and light and dark themes. Checkout is a request-an-order flow, so you submit the cart, the database prices every line, and staff and buyer each get an email.

AI Frontend Advisor
AI AdvisorOpenAI LLM
An AI advisor asks about your framework, bundle budget and accessibility bar, then names two or three UI libraries with the measurements behind each pick and links to its build page and live demo. It answers from a controlled comparison of eight React and Vue libraries that each built the same screen from one frozen spec, and it says so when a question goes past the data.

AI Chatbot Builder
AI RAGAI ChatbotOpenAI LLM
An AI support chatbot that answers your visitors from your own docs, cites the section it used, and says so when the docs do not cover a question. Upload a PDF, a URL or Markdown, set the bot's name, colors and tone, then paste one script tag into any site. The dashboard shows the conversations, ratings and unanswered questions, and the demo needs no account.
