AI-Driven Development:• Hands-on fluency with AI-assisted development tools — using them daily and understanding their strengths, failure modes, and appropriate limits.• Experience building and orchestrating agents: designing agent loops, managing context and memory, composing multi-step pipelines from discrete skills, and handling failure modes gracefully.• Ability to define reusable, well-scoped skills with clear interfaces and predictable behavior — the building blocks of reliable agentic workflows.• Prompt engineering as a first-class discipline: structured prompting, output validation, iterative refinement, and the ability to teach these practices to others.• Practical experience evaluating agent behavior: defining what good looks like, building evals, and holding AI-generated work to the same standards as hand-authored code.• Ability to identify which parts of a development workflow are good candidates for automation or AI assistance and which are not.
Cloud Native & Platform:• Strong working command of containerization and orchestration — building and running services that are scalable, reliable, and operationally simple.• Experience with major cloud platforms and their managed services, with a preference for platform-native solutions over custom infrastructure.• Infrastructure as code practices applied consistently across environments.• Building and maintaining CI/CD pipelines with an emphasis on fast feedback, automated quality gates, and safe deployment patterns.• Distributed systems fundamentals applied in practice: service communication, event-driven patterns, observability, and fault tolerance.
Application Development:• Deep expertise in C# / .NET — platform internals, async programming, and performance optimization.• API design and implementation using ASP.NET Core, including REST principles, versioning, and middleware patterns.• Relational database design, ORM usage, and T-SQL query optimization.• Front-end development with React and TypeScript, including component design and state management patterns.• Proficiency with modern JavaScript/TypeScript, HTML, and CSS.
