• Define standards and reference architectures for React Native/Flutter/Xamarin (or hybrid web-views, Capacitor) and native interoperability.
• Establish mobile domain models, API contracts, security controls, and data governance for mobile.
• Create roadmaps aligned with business OKRs, balancing innovation with platform stability.

• Lead architecture for new mobile initiatives: authentication flows, offline-first patterns, background sync, push notifications, deep linking, app configuration, and feature flagging.
• Design scalable backend integrations (API gateways, GraphQL/REST, caching, pub/sub), and select runtime patterns (BFF, façade services).
• Architect telemetry pipelines for observability (crash analytics, performance metrics, RUM, log aggregation).

• Implement Zero Trust principles for mobile; enforce secure storage, device attestation, jailbreak/root detection.
• Align with OWASP MASVS/MSTG, NIST, ISO 27001; ensure compliance (GDPR, CCPA, HIPAA/PCI as applicable).

• Define threat models, conduct architecture risk assessments, and drive secure SDLC practices (SAST/DAST, dependency scanning).

Platform Engineering & DevOps

• Define CI/CD pipelines for mobile (Fastlane, Bitrise, Azure DevOps, GitHub Actions, CircleCI), code signing, release orchestration.
• Standardize testing strategy: unit/UI/e2e, device farms, accessibility, performance, and compatibility testing.
• Govern app distribution (App Store/Play, Enterprise distribution), versioning, rollback strategies, and release trains.

Scalability, Performance & Reliability

• Architect for offline resilience, concurrency, graceful degradation, and efficient network usage.
• Establish SLAs/SLOs/SLIs for mobile experiences; implement synthetic monitoring, crash thresholds, and performance budgets.
• Optimize startup time, memory footprint, battery usage, and bundle size.

Data & Integration

• Model data flows; select client-side storage (Secure Enclave/Keychain, Keystore, SQLite/Room/Realm, encrypted stores).
• Define API schemas and backward compatibility strategies; manage schema evolution and versioning.
• Champion API governance and service cataloging; integrate with identity (Azure AD/Entra ID, Auth0, Okta).

Governance & Standards

• Maintain architecture repository and guardrails, including coding standards, dependency policies, and modularization.
• Run Architecture Review Boards, perform ADRs (Architecture Decision Records), and maintain tech radar.

Leadership & Collaboration

• Mentor architects and senior engineers; conduct design reviews and coaching.
• Partner with Product, UX, Security, Infra/Cloud, and Business stakeholders; translate business goals into technical plans.

Vendor management:

• Evaluate frameworks, SDKs, third party services; negotiate and manage technical risk.

• 12+ years in software engineering/architecture, with 6+ years leading enterprise-grade mobile solutions.
