Hi, I’m Mark 👋

ML Engineer / R&D Data Scientist

I design, build, and deploy production-grade ML systems — from data ingestion and feature pipelines to model serving, monitoring, and business metrics.


💼 Career Focus

Analytics → Machine Learning → Production ML / MLOps

  • End-to-end ML systems in fintech & industrial domains
  • Credit risk modeling (PD / LGD), regulatory ML
  • Time series & NLP systems with business impact
  • Strong emphasis on reproducibility, monitoring, and validation

🏢 Professional Experience (Highlights)

ML Engineer — Industrial / Mining (R&D)

  • Anomaly detection systems for industrial data
  • OCR models and data processing pipelines
  • Full ML lifecycle: dataset validation → training → deployment → monitoring
  • MLOps stack: Airflow, DVC, ClearML, S3-compatible storage

ML Engineer — Fintech (Banking)

  • Credit risk models for corporate clients
  • Models developed under regulatory requirements
  • Production deployment via Kubeflow & CI/CD pipelines
  • Oracle-based data pipelines and automated data collection

ML Engineer — Product / Startup

  • Built a full ML product from scratch (ETL → models → backend)
  • Multisource ingestion: blockchain, exchanges, social & news data
  • NLP sentiment indices (FinBERT) and Prophet-based forecasting
  • Dockerized microservices and production-ready architecture

🚀 Engineering Highlights
