At DualEntry, I own the backend of the AI agent platform behind Copilot, used by 400+ customer users. I designed an approval flow that lets agents propose changes to the books, wait for a person's sign-off, and resume reliably.
I also built the MCP integration layer connecting agents to external tools, with OAuth, per-user permissions, and isolation between connectors. I added a 100-case benchmark, real-LLM end-to-end tests, and production metrics to evaluate changes before release and track them in use.
At Reddit, I maintained safety services for moderation actions and led the migration of a monolithic service into two independent microservices. I also built automation services to reduce manual administrative work for the safety operations team.
Earlier, at Very Good Security, I designed and built a payment orchestration solution across multiple providers. At Ring Ukraine, I led a team of three engineers and implemented real-time video processing pipelines running ML inference.
