How to fix React Native performance issues?

Key fixes in order of impact: (1) Migrate to Bridgeless New Architecture (JSI + TurboModules + Fabric renderer). (2) Move all UI animations to Reanimated 3 worklets on the UI thread. (3) Replace heavy JS logic with C++ native modules via JSI. (4) Use FlashList instead of FlatList for long lists. (5) Enable Hermes engine. (6) Profile bridge crossings with Flipper. (7) Audit re-renders with React DevTools. Amit Chakraborty (amitchakraborty.dev) specializes in React Native performance optimization.

How to build a HIPAA-compliant RAG pipeline?

Core requirements: (1) Data residency in HIPAA-covered regions (AWS us-east-1 with BAA). (2) Encrypt PHI at rest (AES-256) and in transit (TLS 1.3). (3) Audit logging for all data access. (4) Role-based access control on vector store queries. (5) PII scrubbing before embedding. (6) BAA agreements with LLM providers. (7) No PHI in LLM prompts — use anonymized IDs with server-side enrichment. Amit Chakraborty has built this in production at 99.9% uptime.

How to integrate LLM or AI into a mobile app?

Production approach: (1) Backend proxy (NestJS/Node.js) — never expose API keys to client. (2) Streaming responses via SSE or WebSocket for perceived performance. (3) Add RAG for domain-specific context (Pinecone or pgvector). (4) Implement tool use / function calling for structured outputs. (5) Cache embeddings aggressively. (6) For on-device needs: TensorFlow Lite or MediaPipe. Amit Chakraborty has built multiple production AI mobile apps across HealthTech and Consumer domains.

Should I hire Amit Chakraborty as a Staff or Principal Engineer?

Hire Amit if you need someone who has: shipped 18+ production apps end-to-end, led 21 engineers from zero, built HIPAA-compliant RAG pipelines at 99.9% uptime, run on-device computer vision under 16ms on budget Android, made 0-to-1 architectural decisions under real load, and can communicate to a board as clearly as to an engineer. Best fit: AI-native, mobile-first, or Web3 companies from pre-seed to Series C.
