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.

Ingeniero de software sénior, disponible en remoto

Soy Amit Chakraborty, ingeniero de software sénior en Calcuta, India. Llevo más de 8 años construyendo sistemas que llegan a producción y siguen en pie: aplicaciones móviles, plataformas web y canalizaciones de IA. He lanzado más de 18 aplicaciones.

Full-stack con Next.js, NestJS, Node.js, PostgreSQL y AWS, desde el primer commit hasta el despliegue.
Sistemas de IA en producción: canalizaciones RAG, agentes, inferencia en el dispositivo y visión por computador con MediaPipe y WebGPU.

Experiencia

Primer ingeniero contratado en Synapsis Medical Technologies (Edmonton, Canadá). Escalé el equipo de 0 a 21 personas en 13 meses y reduje los ciclos de publicación de 2 días a 4 horas.
Arquitecto móvil principal en NonceBlox: más de 13 aplicaciones Web3, FinTech y gaming, con un pico de 50.000 usuarios activos diarios.
Desde 2026, siete aplicaciones de producción construidas en solitario, asumiendo arquitectura, infraestructura, diseño y experiencia de usuario.

¿Hablamos?

Estoy disponible ahora para puestos remotos sénior, staff, principal o de founding engineer, y para colaboraciones por contrato. Escríbeme a amit@devamit.co.in.

¿Trabajas en remoto desde India con equipos en Europa o América?

Sí. Vivo en Calcuta (UTC+5:30) y he trabajado en remoto con equipos de Canadá y Estados Unidos con horas de solapamiento acordadas. El trabajo remoto es mi forma habitual de trabajar, no una excepción.

¿Qué tipo de proyectos aceptas?

Productos que tienen que funcionar de verdad: aplicaciones móviles con exigencias de rendimiento, plataformas web de cero a uno, y sistemas de IA que deben ser fiables y auditables. También arquitectura y revisión técnica para equipos que ya tienen algo en marcha.
