Job Success
Mohali, India - 2:16 pm local time
I specialize in integrating AI into real products, not just connecting an API and calling it done, but architecting RAG pipelines, LLM-powered chatbots, AI automation workflows, and OpenAI-backed SaaS features that solve actual business problems. My background in full stack development means I can own the entire product: React/React Native frontend, FastAPI/Node.js backend, cloud infrastructure, and the AI layer, all in one engagement.
Selected results for clients:
→ Helped one client grow revenue 500% through algorithm optimization
→ Led a $500K research project rated "gold standard" by the client
→ Delivered 70+ production systems across web, mobile, and AI domains
What I build:
- AI chatbots and assistants (OpenAI, LangChain, RAG, Pinecone, vector search)
- AI SaaS platforms and MVP builds from zero to production
- OpenAI / GPT / LLM integrations into existing web and mobile apps
- RAG systems: chat with documents, knowledge bases, internal data
- AI workflow automation (Celery, WebSockets, background tasks)
- Full stack web applications (React, Next.js, Node.js, FastAPI, Python)
- Mobile apps (React Native, iOS, Android)
- REST APIs, GraphQL, microservices, and scalable backend architecture
- Cloud deployment (AWS, Firebase, Docker)
- Payment integrations (Stripe, Twilio, third-party APIs)
Industries: healthcare, fintech, eCommerce, logistics, SaaS, social platforms,
edtech, automation, and real estate.
