React Native Developer for my simple calculation App.
If I have to say in one word then "Awesome". This guy are just so so so amazing. Amit is a thorough professional. He is a man of his words. He went so much out of the way to complete my project. He was so careful to explain and upskill me on my app development knowledge. I have been sometimes so demanding but these guys have just risen up to the challenge and done wonders.
My App is very challenging and this guy were patient and supportive even when I made many changes not agreed initially. What's more when lot of others only care about money, Amit only concern was reputation. I mean money can't buy that attitude.
And also can I just say there pricing is out of this world without any compromise in quality or efficiency.
I have never done feedback this long..but this guy have been so unbelievable. I am so grateful. I surely will be coming back to him. I wish him all these best and I am sure he will do wonders.
Thanks Amit.

About Amit
Senior AI Engineer | LLM Apps & RAG | MLOps | 100+ Apps Shipped
Kolkata, India - 2:26 pm local time
I build the second part for a living.
I'm Amit Kumar - 16+ years shipping production software, 100+ apps live across India, Canada, UK, and US. I built Parlix, a multi-tenant AI assistant platform with sub-200ms responses, RAG on actual client docs, native scheduling, voice, and human handoff built in. HIPAA-ready hosting, TLS 1.3 in transit, AES-256 at rest. Deployable on a client site in under 10 minutes, no developer needed.
What I actually ship for AI buyers:
- LLM apps with RAG grounded on your real docs, not synthetic context
- AI integrations into existing stacks - REST/GraphQL, Stripe/Razorpay/Plaid, KYC, CMS, CRM
- MLOps pipelines - CI/CD for models, monitoring, vector DB ops, eval harnesses
- Prompt engineering with eval loops, not vibe-tuning
- AI-focused data engineering - ingestion, embedding pipelines, retrieval tuning
- Mobile + AI - React Native and Flutter, with the OS-lifecycle work that actually keeps the session alive
Stack I work in daily: OpenAI, Claude, LangChain, Pinecone/Weaviate, Python, Node.js, AWS, Postgres, MongoDB.
Credentials: AWS Certified Developer - Associate, Meta React Native Specialization, Google Project Management Certificate.
How I work:
- Hourly $50/hr, adjusted by scope
- Fixed-bid milestones for well-scoped builds
- A 15-minute call before I write a line of code, so the plan is yours, not a templated SOW
- Direct communication, weekly demo, end-of-sprint retro
If you have a real AI problem - not a buzzword brief - and want a builder who's already shipped this pattern, let's talk. Pitch deck on request.
