Presentation
Background
• Created scalable APIs using Node.js/Express.js + SQL for authentication, KYC, multi-currency wallets, deposits, withdrawals, and settlements with a focus on modular architecture.
• Utilized Redis for caching strategies, rate limiting, and message brokering to optimize system performance and ensuring database reliability.
• Implemented real-time bidirectional communication with Socket.IO for live updates and notifications in live order books and trade executions.
• Optimized infrastructure using Docker containerization, AWS SDK for cloud integrations, and Celery for efficient asynchronous event handling.
• Created Grafana dashboards utilizing custom SQL queries to monitor system data in real-time.
• Implemented a proof-of-concept OpenAI CLIP-based document identification system that successfully filters out 1000+ false documents monthly, focusing on optimal efficiency.
• Innovated a method resulting in 1000 times faster OCR processing for specific documents by implementing targeted conditional logic with the PyMuPDF (fitz) library.
• Ensured the stability of data migration systems through comprehensive testing and debugging processes.
