Syntheos.

Hackathon-winning AI tool built in under 48 hours at the Brainrot Jia.Seed Hackathon. Syntheos ingests social media posts and runs them through a multi-stage Gemini AI pipeline — content analysis, audience targeting, and engagement scoring — then returns structured, actionable optimization suggestions in real-time. Designed the prompt chaining architecture to minimize hallucination and keep recommendations grounded in platform-specific best practices. Handled OAuth flows, Firebase session persistence, and streaming responses for instant feedback.
