aryanshah295/devtalks ? reverse-engineered prompt

Build me an app called DevTalks that lets people search conference talks by meaning, not just by exact words.

It should pull in talks from channels like KubeCon, Google Cloud Next, and Spring I O, transcribe the videos, turn the transcripts into semantic embeddings with Vertex AI, and let users search through the results through a fast gRPC streaming API. I want this to feel like a real cloud native learning project, so use Kotlin for the services and make it something that could run on GCP with Cloud Run and Pub Sub.

Please also include a simple frontend so I can try the search and see matching talks, titles, and transcript snippets. If anything is unclear, look up current docs online and make sensible choices. Keep it working end to end, with the ingestion flow, search flow, and basic deployment setup all connected.
