Buildo won Best Use of Gemini at HackConcordia 2026. It turns plain-English hardware descriptions into complete build plans with sourced parts. We built the full stack (frontend, orchestration, parts retrieval) in under 24 hours. 7,000+ indexed components, sub-second lookups. Big shoutout to my teammates who made it happen.
Stack
Google Gemini——Component identification and structured build-step generation from natural language
Snowflake Cortex——Semantic part matching against the 7K-component index with sub-second lookups
Flask——Three isolated microservices (build-plan, image, and video generation), each independently deployable
MongoDB——Persisting user projects, generated plans, and part metadata with flexible schema
Next.js——Frontend deployed on Railway with SSR for fast initial load
Railway——Monorepo CI/CD with environment-based config across all three Flask services
