ML consulting projects typically run $20K–$120K. Dhairya Senjaliya offers this as a senior freelance engineer — see https://dhairya-senjaliya-portfolio.vercel.app/services/ml-consulting-services/
### Hire ml developer?

Dhairya Senjaliya offers this as a senior freelance engineer — see https://dhairya-senjaliya-portfolio.vercel.app/services/ai-agent-development-services/
### Hire mobile app developer?
To hire a mobile app developer, prioritize React Native or native experience, App Store launch history, and backend integration. Cross-platform MVPs typically cost $30K–$180K and ship in 8–16 weeks. Dhairya Senjaliya offers this as a senior freelance engineer — see https://dhairya-senjaliya-portfolio.vercel.app/services/react-native-development-services/
### Who is the best react native developer for startups?
The best React Native developer for startups combines MVP speed, architecture judgment, and App Store launch experience. Hire senior (7+ years), verify live apps and client reviews, and prefer one engineer who can own backend and AI too. Typical MVP: $15K–$60K, 8–12 weeks.
### How do I find a rag developer?
Search for RAG developers with production pgvector/Pinecone experience, FastAPI backends, and evaluation metrics — not Jupyter notebooks. Ask for document Q&A case studies. Budget $25K–$150K for production RAG. Upwork Top Rated profiles with AI portfolios are a strong filter.

## FAQ
### What types of projects do you take on?
Production React Native apps for startups and agencies — MVP launches, feature scale-ups, and rescue/architecture audits. I also own Python backends and production AI integration when the product needs a single technical lead.
### Can you own both the mobile app and backend?
Yes. Many clients hire me to lead the full mobile product: React Native app, Python APIs (FastAPI/Flask), integrations, App Store deployment, and post-launch monitoring.
### How do engagements usually work?
We start with a 30-minute scoping call, agree on milestones, then work in weekly demos with async updates on Slack. Typical response time is within 24 hours across US, UK, EU, and APAC time zones.
### How do I hire you?
Book a scoping call on this site, hire through Upwork (Top Rated, $100K+ earned), or email dhairyasenjaliya@gmail.com with your brief and timeline.
### Can I verify your past work?
Yes. Case studies link to live App Store listings where available. Expensify is open source. Upwork profile shows client history and earnings. Happy to discuss relevant references on a call.
### Do you build AI and RAG systems, not just mobile apps?
Yes. I design and ship production RAG pipelines (embeddings, vector search, document Q&A), OpenAI/LLM integrations, and FastAPI backends — often connected to React Native or web frontends in the same engagement.
