Do You still think coding speed is the bottleneck?

Coding Speed is not the Constraint. Context is.

With Cursor, Windsurf, Roo Code, Claude Code, GitHub CoPilot, we are able to generate entire files, refactor codebases, and autocomplete faster than we could ever imaged. P&L leaders expects that speed will ripple across software development. Yet why haven't we seen ROI increases in most organizations?

Because the bottleneck has moved.

Those AI coding assistants improve the same thing: how quickly code gets written once you already know what you’re building.

The actual constraint in software delivery is context -- the domain business domain context and enterprise proprietary knowledge.

Commonly, the context required to work effectively are fragmented. API contracts live in one place, authentication rules in another. Business workflows exist as diagrams. Articles in Confluence are incomplete, mixed with outdated versions or scattered in different projects. Slack threads, Zoom meetings. Legacy code bases. The list goes on.

Developers spend most time reconstructing, understanding the context than producing code. They require support from product managers. This cognitive overhead compounds with every new service, team, and dependency.

With no sufficient context, it is hard if not possible to turn vibe coding into economic gains in enterprise software delivery pipelines.

I built a RAG as a second brain

I work in software development. On my typical day I go from meeting to meeting and review lots of API contracts and design diagrams. The other day I simply couldn't recall something in a group discussion (I guess my brain was overloaded).

Then it hit me: Why don't I build an app to house all stuff I have gone through so I could ask it for anything whenever? Works like the Pensieve in Harry Potter Dumbledore stores and retrieves memories. 🧙‍♂️ 🪄 It is like my second brain.

So I vibe-coded Second Brain -- a private #RAG to serve as a digital twin for your personal and/or professional knowledge base.

This is a submission for the New Year, New You Portfolio Challenge Presented by Google AI

About Me

Developer by heart and Product Manager in brain

Portfolio

WHUT Weather Reporting System is a fully functional weather reporting platform that leverages Google Cloud AI and modern cloud-native technologies to fully autonomously generate, store, and deliver weather forecasts with text, audio narration, and visual imagery. The system uses a team of AI agents to create professional weather reports and serves them through a modern web interface, with no human intervention.

System In action: https://weather-station-951067725786.us-central1.run.app

How I Built It

Tech Details

What I'm Most Proud Of

Fully autonomous system. Demonstrate a multi-modal and multi-agent system can complete an operational function of a typical weather reporting organization
Cutting-edge AI technologies. Leverage Multi-modal Gemini & Imagen, ADK Multi-Agent, MCP server, and Google managed serverless services (Cloud Run, CloudSql)
Extensible platform. Easily add additional functions of a news reporting organization
Extreme Cost Efficiency: One report production costs less than 50 cents, end-to-end. The content is generated on-demand in response to viewer requests.

Thanks for hosting this challenge!
