• You build and maintain backend services, APIs, data persistence, and frontend interfaces — design decisions are made collectively • You work in small increments, integrate frequently, and keep the codebase in a releasable state at all times • You design APIs with the consumer in mind: intuitive, versioned, consistent, and built to evolve. • You co-own data modelling decisions with your team: schema design, query patterns, and migration strategy • You write automated tests as a first-class deliverable — unit, integration, and API-level — and instrument your software for observability from day one. • You improve existing code as you go — refactoring is part of delivery, not a separate activity • You deploy and operate software as a team — everyone understands how the system runs in production, not just the person who last touched it • You document design decisions, API contracts, and domain knowledge clearly in writing, and communicate proactively about blockers, tradeoffs, and progress • You pair with teammates regularly and share effective patterns and tools — including AI workflows — with the team • Code review is a team practice, not a gate. You give feedback that improves the code and the engineer, and you receive it with the same openness
