• Ability to operate as a one-person product strike team when needed.
• Ownership of outcomes end to end: clarifying problems, defining product behavior, implementing frontend, coordinating backend work, and shipping.
• Strong enough in frontend to review React code independently and reason about APIs, data models, permissions, backend constraints, and edge cases.
• Use AI to accelerate development while verifying and adapting output before code review.

Not suitable if:

• Looking for a pure frontend implementation role with detailed tickets, finalized designs, and predefined APIs.
• Expect product managers, designers, or backend engineers to make the hard product and technical decisions before you start.
• Prefer narrow specialization, heavier process, or avoiding ownership of backend or UX constraints and AI-assisted output quality.

• Turn ambiguous product problems into clear user flows, product behavior, edge cases, and success criteria.
• Build and maintain scalable, modular, high-performance frontend code.
• Review backend and frontend implementation independently across UX, code quality, performance, accessibility, maintainability, and product correctness.
• Define API contracts and backend expectations clearly.
• Collaborate with backend engineers on architecture, data models, permissions, error handling, observability, and performance.
• Use AI tools to accelerate prototyping, implementation, refactoring, testing, debugging, and technical exploration.
• Critically review AI-generated output and stay accountable for correctness, maintainability, and product quality.
• Balance speed, simplicity, performance, maintainability, and user experience.
• Keep the end user, business impact, SEO, accessibility, and product quality in mind.
