Senior Fullstack / AI Agent Engineer — multi-agent pipelines, MCP, production AI systems.

I design, build and operate AI agent systems end to end. Most recently I was the sole engineer on an AI-visibility (GEO) platform: multi-agent pipelines, a Node.js API and workers, a Next.js dashboard and two MCP servers — architecture to production.

• 🤖 Multi-agent pipelines and the runtimes that schedule, trace and recover them
• 🔌 MCP servers exposing systems to AI clients and tooling
• 🧪 Evaluation and observability for non-deterministic agents (OpenTelemetry)
• 🌐 Fullstack: TypeScript · Node.js · Next.js · React · Python · FastAPI

• team-bootstrap — role-based AI delivery framework for coding agents: pipelines, an independent verifier, hook-enforced guardrails, OpenTelemetry tracing and an eval harness.

• Hyperskill's testing frameworks — hs-test (Java/Kotlin), hs-test-python, hs-gradle-plugin.
