• Uphold SOLID principles, Dependency Injection, and Hexagonal Architecture.

• Design and sustain the agent context layer featuring standardized Skills, Rules, and Commands.

• Develop and manage Model Context Protocol (MCP) servers that transform legacy APIs, services, and databases into typed, secure, AI-friendly resources.

• Lead contract-first API design that bridges human intent with autonomous agent execution.

• Serve as the architectural gatekeeper for AI-generated pull requests.

• Enforce test-driven development and characterization testing throughout the refactoring process.

• Oversee and enhance agentic reasoning loops for cost efficiency, speed, and architectural soundness.

• Strong practical knowledge of TypeScript, .NET, and Node.js.

• Solid foundation in API design, distributed systems, and modular architectures.

• Hands-on experience with agentic development, MCP, LLM tooling, or AI-assisted engineering.

• Preference for clean code, deterministic systems, and production-level AI.

• Experience in remote-first or globally distributed teams.

• Background in SaaS transformations, scale-ups, or private equity-backed environments.

• Comfort in navigating high-ambiguity, high-ownership environments.
