C# Python OpenAPI Docker GitHub Actions

I build production backend systems, trading infrastructure, APIs, SDKs, and internal tools with C#/.NET and Python.

At Bybit, I maintain official OpenAPI SDKs and integration examples, build developer tooling, and debug real-world REST and WebSocket integrations.

I also enjoy cybersecurity research: primarily web application penetration testing, but also generally finding gaps between how software is supposed to act versus what I can make it do.

Open source at Bybit

  • pybit — official Python HTTP and WebSocket connector
  • API documentation — reference docs and integration guidance
