Jasper Rexford

I build and ship agentic AI systems, reverse-engineered integrations, and automation infrastructure end to end. At Axtrize, I built Subtitle Forge, an agent-operated pipeline that turns a topic into a fully rendered 60fps video through a master-orchestrator and sub-agent architecture.

I design systems that make agent output verifiable: Subtitle Forge includes a 41-check preflight validation gate, and my Claude Code lifecycle hooks capture corrections, propose patterns, and automatically update agent instructions. I also build MCP servers in Go and Python, including a process-verified secrets server using SO_PEERCRED and Nix store-path pinning.

I reverse-engineer undocumented web and GraphQL APIs from Electron and browser clients to create protocol libraries, session-riding integrations, and platform controllers based on captured real traffic.

Across TypeScript, Go, Python, SvelteKit, NixOS, and self-hosted infrastructure, I work from a problem to a deployed system. I bring a forward-deployed approach: test-driven agent workflows, infrastructure as code, regression suites, and small verified increments.
