Hi, I'm Hüseyin Pekkan 👋

AI/ML Engineer · Computer Vision · RAG & NLP · Production Systems

I build practical AI systems that move from research notebooks to real production environments.

My work focuses on computer vision, multi-object tracking, segmentation, legal AI / RAG systems, remote-sensing workflows, and backend infrastructure for ML products. I enjoy designing end-to-end pipelines: from data ingestion, model experimentation, retrieval systems, and evaluation to FastAPI services, Docker/Kubernetes deployments, observability, and production iteration.

About Me

I am an AI/ML Engineer with experience across:

  • Computer Vision: object detection, segmentation, multi-object tracking, real-time CCTV analytics
  • RAG & NLP: hybrid retrieval, vector databases, legal AI systems, citation-aware generation
  • Production ML: FastAPI services, async backends, Docker, Kubernetes/K3s, Redis, Celery
  • EO/GIS Analytics: remote-sensing experiments with Sentinel/Landsat imagery and Google Earth Engine
  • Research & Experimentation: medical imaging augmentation, NLP classification, geospatial AI workflows

I like building systems that are not only accurate, but also observable, maintainable, deployable, and usable.


Current Focus

Computer Vision YOLO / YOLOE, U-Net, GAN/DCGAN, OpenCV, BoT-SORT, ByteTrack, real-time video analytics
RAG & NLP Hybrid retrieval, dense + sparse search, reranking, Qdrant, pgvector, Hugging Face, citation-aware LLM systems
Production Systems FastAPI, PostgreSQL, Redis, Celery, Docker, Kubernetes/K3s, Linux, REST APIs
MLOps & Observability OpenTelemetry, Prometheus, Grafana, structured logging, deployment pipelines
EO/GIS Google Earth Engine, Sentinel/Landsat imagery, urban heat island analysis, geospatial segmentation

Real-Time Marina Vessel Tracking

Designed and deployed a real-time vessel tracking system from overhead CCTV footage.

Key areas:

  • Boat detection with YOLO-based models
  • Travel-lift / boat-hoist detection with YOLOE segmentation
  • Multi-object tracking with BoT-SORT
  • Zone and line-crossing logic
  • Debounce state machines for reliable counting
  • Annotated output videos with live HUD, entry/exit counters, and event logic

EO/GIS & Remote Sensing
