Can you build a production mobile app in React Native?

Yes — I ship native iOS and Android apps from one Expo/React Native codebase, with payments, provisioning, offline-first flows and clean native integrations.

Q: How do you actually implement AI in a business?

I find where AI creates real value, design the architecture, and build it end-to-end — running systems, not slideware.

Q: Can you build AI into a healthcare product?

Yes — I have architected clinical decision support, AI meal analysis and LLM health assistants on a custom model + vector database, with the privacy and reliability healthcare demands.

Q: How do you scale a Node.js backend?

With the right architecture: services split by load, event streaming, queues and caching, observability, and databases chosen per workload — proven on a platform that grew to 3M+ users.

Q: Can you build an MVP and then scale it?

Yes — I build MVPs end-to-end fast, then evolve the same codebase to production scale instead of throwing it away. Several of mine grew to acquisition or millions of users.

Q: How do you build a project with agentic AI development?

I drive AI coding agents (Claude Code, Codex, Cursor) with custom rules, hooks and context, spec-first — then gate everything with tests and AI review so speed never costs quality.

Q: How do you use CodeRabbit for code review and quality?

CodeRabbit reviews every pull request automatically — catching bugs, security issues and smells — as a gate alongside human review and a real test suite, so nothing weak reaches main.

Q: Can you build a custom AI model for my product?

Yes — self-hosted models on Ollama (Llama, Mistral, DeepSeek), fine-tuned or RAG-grounded, when you need privacy, control or a task an off-the-shelf API can’t do well.

Q: How do you build a RAG system?

Chunk and embed your data into a vector database, retrieve and rerank the right context per query, ground the model in it, and evaluate — so answers are accurate and cite your sources, not hallucinations.

Q: Which AI model should you use — Claude, GPT, Gemini, Perplexity or Grok?

It depends on the task — and the real answer is usually more than one. I pick and route across frontier models by strength, with evals and fallbacks, so you get the best result without lock-in.

React Native done well gives you one codebase, two native apps, and real hardware access — without a compromise on quality. I have shipped mobile products to the App Store and Play Store across fintech, travel, health and networking, with the parts that usually go wrong (payments, provisioning, offline) done properly.

One codebase, genuinely native features

On Expo/React Native I have built NFC/QR digital business cards (Cardly), an eSIM app with QR / one-tap provisioning (AloAlo), an AI product-scanner (Sumus) and health apps — using Expo Router, TanStack Query, react-hook-form and Zod, plus native modules where the platform demands it. The result feels native because the hard integrations are native.

Payments, auth and offline that hold up

The failure points in mobile are rarely the UI. I wire Stripe and RevenueCat subscriptions, Supabase/NestJS backends, secure auth and offline-first data so the app keeps working on a bad connection and money flows reliably. Weekly production releases keep the loop tight.

AI on the phone, backend behind it

Because I also build the backend and the AI, mobile features that depend on a server — scan-to-insight, LLM chat, personalised recommendations — come together as one system instead of three teams negotiating an API. That is how Sumus’ scan-and-score and Ealthiness’ AI meal analysis shipped.

Key points

Native iOS + Android from a single Expo/React Native codebase.
Payments (Stripe/RevenueCat), secure auth and offline-first done right.
Mobile, backend and AI built together as one coherent product.
