• Build UI features end-to-end: implement Vue UI, define clean UI↔Lua contracts, and collaborate with Lua specialists (you can handle basic Lua glue when needed). • Make UI fast and stable: profile and optimize rendering/layout/update frequency to reach a 60 FPS feel where it matters, and keep long-running sessions leak-free. • Keep business logic in Lua: keep Vue focused on presentation and simple UI state; avoid moving backend logic/data conversions into JS. • Work with real-time data: design UI that stays responsive while receiving frequent updates from the game/simulation. • Own navigation/input correctness: integrate scoped navigation and UI event handling so screens behave correctly with gamepad/keyboard and don’t leak inputs to parent scopes. • Improve developer experience: small, practical improvements to tooling/pipelines, debugging helpers, and performance instrumentation. • Support the team: review code, help juniors grow, and keep quality high without over-engineering.

• Act as a long-term technical steward for Alpaca’s frontend architecture (2–5 year horizon). • Design and evolve scalable frontend patterns for data fetching, state management, performance, and runtime configuration. • Drive large-scale initiatives such as: • Design system evolution and adoption • Frontend platform standardization • Performance, reliability, and developer-experience improvements. • Identify and reduce systemic frontend technical debt with measurable business impact. • Lead cross-team, multi-quarter initiatives spanning multiple product areas. • Define rollout strategies that enable change without blocking feature delivery (e.g. phased migrations, feature flags, compatibility layers). • Partner with backend and platform teams to solve end-to-end system problems, not just frontend symptoms. • Influence engineers and leaders across the broader engineering organization. • Write RFCs, decision records, and architectural proposals that align teams and drive adoption. • Mentor Senior Engineers and help raise the overall frontend engineering bar. • Navigate conflicting opinions and help teams disagree and commit. • Take loosely defined business problems and turn them into clear, actionable technical initiatives. • Manage risk in large migrations, architectural shifts, and platform-level changes. • Balance short-term delivery with long-term sustainability, even when ROI is not immediately visible.
