Mark Frost
Senior Software Engineer · Ruby on Rails · AI/MCP platforms
Backend engineer with 10+ years in Ruby on Rails (since 2014) and 4 years on a multi-tenant data platform for commercial real estate: ETL from 11 property-management and accounting systems, a PDF/Excel reporting engine, and an AI layer (in-product MCP server, LLM assistant, AI report widgets). I like owning a module end to end: R&D, data model, API contract, migrations, and the boring reliability work that keeps it running.
