PXX SPARK.

The Overview

PXX SPARK is a fully autonomous AI agent designed to manage internal knowledge sharing. Unlike standard chatbots, SPARK features a self-optimizing "Reinforcement Learning" loop that analyzes user engagement (reactions & comments) to dynamically adjust its future content strategy without human intervention.

The Architecture

Instead of a single prompt, I architected a chain of specialized AI agents to ensure reliability and autonomy:

• Generator AgentDrafts 3 unique tips based on the selected topic using Google Gemini 2.5 Flash.
• Validator Agent (L2)Acts as a quality gatekeeper, reviewing drafts against strict guardrails (tone, length, policy) and selecting the single best version to publish.
• Learner Agent (RLHF)Analyzes post-performance metrics (upvotes/downvotes) to update the database state, prioritizing successful topics for future generation.

Infrastructure & Impact

To ensure data privacy and security, I containerized the entire application using Docker and deployed it on a self-hosted on-premise server. I also designed a custom PostgreSQL schema to track historical performance and prevent content repetition. Since deployment, the agent has maintained 100% uptime and successfully automated the weekly knowledge-sharing workflow.
