Cross-Functional Collaboration:  Partner with product and design teams to translate user needs into thoughtful, intuitive, and performant experiences. End-to-End Thinking:  Architect, implement, test, deploy, and measure features with a focus on long-term maintainability and system integrity. Experimentation & Analytics:  Instrument features using PostHog, run experiments, analyze real user data, and iterate based on measurable outcomes. AI-Driven Engineering:  Leverage modern AI development workflows to increase velocity, structure context effectively, and deliver production-ready systems. Continuous Improvement:  Identify opportunities to refine architecture, improve performance, and scale systems while maintaining engineering excellence.
