year: 4th (Final Year)
thesis: RAG Pipelines & LLM Evaluation
focus:
- Fullstack web engineering (Next.js, Node.js, PostgreSQL)
- LLM products with grounding, evals & usage budgets
- Desktop apps for real clients (Electron, SQLite)
- Real-time systems & production deployments (Docker, Vercel, Render)
status: Always learning- 🎯 Job Hunt Copilot — LLM app that scores a job ad against your CV, backs every claimed match with a verbatim CV quote, and writes a cover letter that addresses the biggest gap instead of hiding it
- 🔧 Repair Shop Management App — freelance Electron desktop app delivered to a real business, replacing a legacy MS Access database (offline-first, PIN-locked, Excel/Access import)
- 🔬 Thesis — developing & evaluating RAG pipelines for LLM performance at UMacedonia
