About Me

I am a data scientist who loves turning raw data into AI systems that deliver tangible business value. I have built fraud models, scheduled pipelines, and simple APIs. My stack includes Python, Airflow, Docker, and AWS to make workflows repeatable. My professional motto is to keep learning, build systems that act, learn, and automate useful work.

Experience

baly.iq (Rocket Internet)
Sep 2024 – Sep 2025: Data Scientist

• Deployed Docker-based services to deliver business features quickly, coordinating with tech and ops.
• Automated fraud-data pipelines with Airflow, reducing manual work by 30%.
• Tuned databases using Percona PMM, improving query response by 20% and ensuring 99.8% HA.
• Deployed containerized services using Docker and Ansible to deliver key business features faster.

snapp.ir (Rocket Internet)
Sep 2021 – Sep 2024: Fraud Data Analyst

• Investigated 35M+ weekly transactions to detect unusual patterns and report findings.
• Built SQL detection rules and Python scripts to flag abnormal transactions, reducing processing time by 40%.
• Collaborated with cross-functional teams to refine business rules.
• Learned automation and containerization to build scalable fraud-detection tools used in production.

Projects

Smart Telegram Bot using n8n

Built an automation workflow connecting a Telegram bot to OpenAI GPT via n8n; used ngrok for SSL and short-term context memory in chat responses.

LLM Fraud Detection

Designed a transformer-based LLM model for Arabic fraud-text detection with reproducible pipelines. [GitHub]

Interactive Model Interpretation Dashboard

Developed SHAP and feature-importance visuals with FastAPI backend and Docker deployment. [GitHub]

S3-MinIO Starter Kit

Created an S3-compatible local storage using Docker + MinIO for testing pipelines; later deployed on AWS EC2. [GitHub]

Algorithmic Trading System

Worked in a small research group building an algorithmic-trading framework for XAUUSD and major forex pairs. Processed 5-minute timeframe market data with Polars for feature generation based on price-action patterns and technical indicators. Used MetaTrader 5 in Docker containers for live data collection and feed simulation, linking it to a local database for real-time updates. Leveraged TradingView for pattern classification and Forex Factory for macro-event features such as Federal Funds Rate changes. Ran experiments and model backtests on Kaggle with the Weights & Biases tracking tool to study models’ behavior and refine their parameters.

COVID-19 Prediction

Built a predictive model for COVID-19 death counts using time series methods. [Colab]
