πŸ” About

Computer Science student focused on AI / Computer Vision, cloud-native backend, and embedded control systems.
I like building end-to-end systems: from research + modeling β†’ to production-ready services.


πŸ§ͺ Experience

Research Assistant β€” Politehnica University of Bucharest (May 2025 – Sep 2025)

  • Applied research on AI-based anti-plagiarism for real-time exam monitoring & behavioral analysis
  • Built an ESG analytics pipeline using LLMs to extract indicators from corporate reports & compute ESG scores
  • Designed & deployed cloud-native services using FastAPI + Docker + AWS EC2 for scalable processing :contentReference[oaicite:1]{index=1}

⭐ Featured Work

1) Anti-Plagiarism System for Exam Monitoring (Computer Vision)

  • Real-time monitoring system combining gaze tracking + cheating device detection
  • MediaPipe Face Mesh (468 landmarks) + Kalman filtering for temporal smoothing
  • Dual YOLOv8 models for smartphone / smartwatch detection
  • ~25+ FPS CPU-only, under 820 MB RAM, 92.4% gaze accuracy
  • First-author paper @ RoEduNet 2025 (ISI Indexed) + extended as Bachelor’s thesis :contentReference[oaicite:2]{index=2}

2) Hold My Coffee β€” Active Stabilization Platform (Embedded Control)

  • Built a 3-DOF stabilization platform with a dual-MCU architecture
  • System identification + reduced-order modeling
  • Implemented & compared PID, RST, LQR, MRAC on real hardware
  • Proposed a CPA metric for multi-criteria controller evaluation (paper in preparation) :contentReference[oaicite:3]{index=3}

3) ESG Analytics Platform (LLM + RAG + Cloud)

  • End-to-end platform for ingesting large PDF sustainability reports and extracting structured ESG indicators
  • Implemented LLM-based RAG to identify metrics, values, units & context
  • Containerized backend (Docker) exposing async FastAPI services for parsing, embeddings, retrieval & scoring
  • React dashboard + PostgreSQL; supports multi-document aggregation, trends & KPI visualization :contentReference[oaicite:4]{index=4}
