Fusion | Built with Google Gemini: Writing Challenge

Source: Dev.to

Overview

This is a submission for the Built with Google Gemini: Writing Challenge.
At Cal Hacks 12.0, I built Fusion, an all‑in‑one platform dedicated to helping engineering managers manage multiple tools—including GitHub, Slack, Notion, and Jira. Powered by Gemini, Fusion allows users to use natural language to perform actions across these platforms, reducing context switching.

Features

• Read Notion documents & databases
• Create and review GitHub pull‑request requests
• Create tasks on Jira
• Read, summarize, and send messages via Slack

What I Learned

• Integrating many platforms required deep dives into each platform’s documentation. This highlighted the importance of clear, detailed docs—not only for using APIs but also for creating my own documentation.
• I had never used Gemini’s tool‑calling before, so learning and implementing it was both fun and educational.
• I encountered several roadblocks outside my control, which taught me how to navigate unexpected issues and plan contingently.
• The Gemini API and function calling were straightforward to work with; the main limitation we faced was rate limiting on the free plan.
