I've built real-time scanning and data aggregation systems across 75+ centralized and decentralized exchange sources, surfacing 15–20 actionable events daily through Python, Selenium, and direct order-book scraping.

As an independent consultant, I architect and operate 24/7 microservice-style production systems using Python, TypeScript, TCP sockets, Docker, and MySQL. These systems have handled 350+ ETH in cumulative transaction volume across multiple networks while maintaining uptime through supervisor patterns, exponential backoff, and self-recovery logic.

I've developed regression, integration, end-to-end, UI, and API automation frameworks using Selenium, Playwright, Pytest, Postman, curl, and Python REST clients. I also investigate defects and validate multi-million-row datasets with SQL, structured logging, historical state recovery, and operational dashboards.

At Piri.ai, consulting for ZPE Systems, I built Jenkins CI/CD pipelines and Python Selenium automation with Pytest and Allure reporting. I use Claude daily for code review, debugging, architecture decisions, test-case generation, and identifying edge cases across complex multi-service systems.
