Demonstrated experience tailoring agentic coding environments to project-specific conventions, including custom workflows, lifecycle automation, and tool integrations, with measured impact on team velocity and code quality. Experience architecting systems with AI-maintainability in mind, including schema-first patterns, single-source-of-truth derivations, clean module boundaries, and predictable interfaces that reduce LLM hallucination surface area. Track record of designing or adopting code conventions and engineering guardrails that prevent common LLM failure modes such as hallucinated APIs, scope creep, type-system bypasses, and schema duplication.

Experience producing and maintaining technical documentation in formats that AI tools can read, write, and keep in sync with code, including code-based diagrams, decision records, and domain references. Ability to evaluate AI tooling options across cost and capability tiers, and to make selection decisions appropriate to team segment, task type, and quality/cost tradeoffs.

Ability to evaluate AI tooling options across cost and capability tiers, and to make selection decisions appropriate to team segment, task type, and quality/cost tradeoffs. Familiarity with model reasoning-depth controls and their cost-quality tradeoffs, and a habit of applying new prompt patterns and model capabilities as the frontier evolves. Expansive familiarity with the information sources, communities, and channels that surface cutting-edge AI capabilities, tooling, and trends.

Experience designing AI-augmented CI/CD pipelines - code review, eval gates, test generation, changelog generation, deployment-aware automation - and measuring their impact on PR throughput, bug rates, time-to-merge, and code-review burden. Experience leading refactoring, migration, or modernization work with AI tooling as a force multiplier, with concrete examples of velocity and quality outcomes. Familiarity with empirical AI productivity research and the practice of validating tool adoption with measurement before scaling.

Track record of mentoring engineers across mixed AI-fluency levels and cost / IP / budget constraints.
