You will get a RAG AI knowledge base that answers from your documents
Project details
You will get a Retrieval-Augmented Generation (RAG) system that lets an AI answer questions accurately from your own documents, PDFs, docs, web pages, or databases, with source citations and minimal hallucination. I handle document ingestion, chunking and embeddings, vector search (Pinecone, Weaviate, pgvector, or Chroma), and OpenAI or Claude on top, with a clean chat UI. With 9+ years of full-stack experience and a 100% Job Success score on Upwork, I deliver everything from a quick prototype to a production system with auth, analytics, and deployment.

Full-Stack Developer for Phase 3 Development of our application
When we started the project with him it was on schedule and they were prompt as well. It was going good. But as we progressed to other tasks, their lack of communication and quality of work reduced drastically. I had to end the contract with them because they won't reply anymore. It's one thing that you are having issues and you are unable to resolve them and another to simply ignore and stop responding. I gave them enough chances to connect and discuss whatever was happening, if they were unable to continue, they could have just said that it would not work between us. They simply take no pride in the work they do and don't care about the quality of code. Their dev always did half done work and we ended up making subtasks because things would not be done in a single go despite my being available during their working hours to answer any doubt or question they may have, rarely I was approached, I had to force meeting with their dev to ensure they are not going in the wrong direction and wasting time in redoing things. We had a fixed cost arrangement so it was financially sound for us, but if we paid them hourly, would have been a disaster. My advice to them would be to take pride in the work they do, provide quality work and most importantly communicate well.

I take projects from architecture to production: clean front ends, solid APIs, well-designed databases, and cloud deployments that hold up under load. Recently I've focused on AI-integrated products — LLM pipelines, smart automation, and the engineering that turns an idea into something that actually ships.
What I build:
• Web apps — React, Next.js, Vue, Angular, Node.js, Express, Python
• Mobile apps — React Native and Ionic
• AI features — OpenAI/LLM integration, prompt engineering, OCR & NLP pipelines, AI-driven dashboards
• Cloud & DevOps — AWS and Azure, Docker, CI/CD automation for fast, secure releases
A few things I've shipped:
• An AI-enhanced HRMS platform with resume screening, payroll, and workforce analytics
• A GPT-powered interview-simulation app that generates and scores mock interviews
• A clinical-operations platform with an ETL pipeline that migrated 20GB+ of legacy data
• A fintech wallet with eKYC and Aadhaar-based eSign verification
Why clients keep coming back:
• Reliable and on time — my reviews mention it more than anything else
• Clear communication — I respond within a few hours and keep you in the loop
• Built to last — clean architecture and secure systems, not quick hacks
If you've got a web, mobile, or AI project that needs someone who can own it end to end, send me a message and tell me what you're building. Let's make it real.
