I'm building toward backend + software engineering roles, with a genuine curiosity for AI/ML on the side and a Power BI + outreach background that keeps me equally comfortable talking to data and to people. Still very much in build-and-break-things mode, and loving every part of it.

Most retrieval systems treat every question the same way — fixed context, hope for the best. AegisRAG doesn't. It classifies incoming queries first, then dynamically adjusts how much context it pulls in based on how complex the question actually is, before generating an answer from the source PDF.

• 🧠 Intelligent query classification before retrieval even happens
• 🎯 Dynamic retrieval depth — simple questions get lean context, complex ones get deep context
• 🔍 Semantic search across PDF content instead of dumb keyword matching
• 📄 Built for real document understanding, not just Q&A theater
