Automated Trading Platform
FEATURES:
• Crawlers fetching L1 market data and storing it inside an internal data warehouse
• A connectors library providing unified access to different exchanges using REST and WebSocket protocols
• An execution library containing different execution strategies optimizing trade execution
• Different trading robots using machine learning models and different quantitative strategies

WORK DONE:
I created many parts of the system from scratch and then as a CTO was responsible for managing the IT department: tech leadership, people management, budgeting, and so on.
