• Designing and delivering production-grade features end-to-end across Java (Spring Boot) backend and React frontend. • Driving full-stack architectural choices on a greenfield codebase - data models, API contracts, service boundaries, frontend state architecture. • Using AI agents and LLM-based tooling daily - for technical research, evaluating libraries and design trade-offs, generating and refactoring code, debugging, and writing tests. • Identifying repetitive parts of the development lifecycle (code review prep, documentation, ticket grooming, test scaffolding, release notes) and building AI-driven automations around them. • Leveraging LLMs and agentic workflows to rapidly digest technical documentation, RFCs, and vendor specs - turning hours of reading into actionable architectural input. • Working directly with business stakeholders - translating fuzzy requirements into clear technical scope, pushing back where it matters, and co-shaping the roadmap. • Operating in a Scrum cadence with the maturity to keep ceremonies useful and lightweight, not bureaucratic.
