I build production-grade React Native applications designed for real-world constraints: offline usage, degraded networks, and long-term maintainability.
- Architecture: feature boundaries, typed data flows, navigation at scale
- State & storage: durable local state, persistence strategies, sync readiness
- Native integration: TurboModules, platform-specific performance paths
- Delivery: release stability, crash resilience, upgrade strategy

I design systems under zero-trust assumptions, where sensitive data is protected by default and trust boundaries are explicit.
- Local encryption and secure storage models
- Sync protocols that avoid implicit trust in backend or transport
- Authentication flows (passkeys, recovery, device linking)
- Threat modeling aligned with product UX

I treat performance as a first-class product feature, not a post-release fix.
- Instrumentation: startup (TTFF/TTI), render cost, thread utilization
- Tracing: event timelines, spans, bottleneck identification
- Benchmarking: reproducible tests for regressions
- Tooling: SDKs and dashboards to make performance visible

I build product-facing ML pipelines where imperfect data must still produce usable outcomes.
- OCR pipelines with preprocessing + normalization
- Structured extraction and confidence scoring
- Human-in-the-loop review workflows
- Dataset evaluation and iteration tooling

I build backend systems that support mobile products cleanly and predictably.
- Typed APIs and relational data modeling
- Sync-aware backend design (conflicts, revisions, auditability)
- Background jobs and operational workflows
- Containerized deployment and service orchestration
