AV Design & Engineering Suite

An AV design workspace for engineers to create floor plans, signal diagrams, and rack layouts, then generate equipment lists and cable schedules.

My contribution:Built React Flow and TypeScript editors that connect equipment across design views and generate engineering documents.

One set of equipment data supports both the drawings and the documentation engineers use to deliver a project.

AI / Vendor pricing

Sheet Parser

An AI application that turns vendor price sheets into structured pricing data, keeps a shared vendor catalog, and organizes prices by project.

Project scope:Connects React and Node.js with OpenRouter LLMs for price-sheet parsing, with vendor and project data stored through Prisma in PostgreSQL.

Teams can organize pricing by project while retaining a shared view of vendor data across the workspace.

How I work

01

Start with the workflow

Understand who uses the product and what they need to do. Map the data and API boundaries before building the screens.

02

Build in small steps

Connect typed interfaces and APIs in small, reviewable changes. Use AI tools for implementation support, then review and test the result.

03

Follow through

Investigate slow queries and failed requests. Improve caching, error handling, and integrations as the product evolves.

Writing

How the implementation works.

Practical guides to AI-assisted development, React and Node.js architecture, and the system design decisions behind a price-sheet parser.
