• Build Node.js BFF & Kotlin services for property management, payment processing, search relevance, guest lifecycle, and efficiency features leveraging event streaming where valuable

• Collaborate with product & design on roadmap sizing, sequencing, and MVP scoping

• Implement API + data changes enabling new UI capabilities (validation, lifecycle state transitions, reporting)

• Design & implement migrations (.NET Framework 4.8 → .NET 8 minimal APIs / ASP.NET Core)

• Lead design reviews; produce ADRs clarifying trade‑offs

• Elevate testing strategy (contract, integration, perf, load)

• Automate observability (structured logging, tracing, metrics, dashboards)

• Mentor SDE I/II engineers (pairing, scoped delegation, review coaching)

• Guide containerization & AWS deployment (ECS/Fargate, selective Lambda)

• Partner with product managers to define KPIs (conversion, booking modification success, statement generation time)
