Python Developer | API Integration, Automation & Data Processing
I develop Python and TypeScript tools for API integration, workflow automation, and data processing.
Personal project experience:
- Real-time market data and signal systems using WebSocket collection and asynchronous processing.
- Financial time-series analysis and backtesting, including checks for future-data leakage.
- Parquet data ingestion and period-based analysis using DuckDB and Pandas.
- PyTorch LSTM and Attention experiments with checkpoints and learning-rate scheduling.
- MCP tools for paper search and AI architecture suggestions.
- A sales and inventory operations console built with synthetic data.
These are personal development and research projects, not claims of paid client delivery.
Skills: Python, TypeScript, FastAPI, SQL, REST APIs, WebSocket, Pandas, DuckDB, PyTorch, MCP.
Education: Bachelor’s degree in Statistics and Data Science, Korea National Open University, 2026.

Work Terms
I confirm requirements, API documentation, sample data, deliverables, and acceptance criteria before starting. I provide source code and setup instructions within the agreed scope. Korean is my native language. For English, I prefer written communication; spoken conversation is limited.
