_{Let’s build useful, explainable AI — fast.}

I build end‑to‑end, production‑ready AI systems — from robust data pipelines and feature engineering to model training, API deployment, and observability.
LLM/RAG applications, agentic AI, and MLOps are my jam: I turn real‑world problems into measurable impact.
- LLMs & RAG with LangChain + vector DBs (Neo4j) • explainability & evaluation
- Data engineering with Pandas/Spark • CI/CD for ML (GitHub Actions, Docker, MLflow)
- Clear communication: dashboards, KPIs, and insights for stakeholders

📈 EDA + anomaly detection on 7k+ gameplay logs → clear learning trends for educators
🧠 RAG + Neo4j recommender (LLMs, LangChain) → ~75% matching accuracy
⚡ Eventify (real‑time dashboards, WebSockets, MFA/RBAC) → +25% user engagement
🩺 Medical ML: AUROC 0.78 (radiomics, SVM) • 🎙️ SER CNN → 85% weighted‑F1
🧰 Reproducible ML: MLflow + Docker + CI/CD
