Project details

I can go from design to a fully developed and deployed web app and website
The web apps will mostly be Django backend and HTML, CSS, JavaScript, Bootstrap, Tailwind CSS, or ReactJS and NextJS in the frontend. The web app may be a blog, news portal, e-commerce, authentication, or even a social app. I can also develop any web app per the client's requirements. So all in one is what sets me apart from others.

Full-Stack Next/React Chat App with Anthropic API + Live Data Panels Nirajan built our email client surface and a change-order round on top of it, and both landed clean and on scope. What set him apart was judgment beyond the ticket: he ran a read-only audit of our backend unprompted, told us the unauthenticated read routes were the thing to fix before anything else, and he was right. That call held up months later when we verified it. He also finished work he hadn't billed for and told us not to charge for it. Clear communicator, honest itemized pricing, no hand-holding required, and completely professional through a stretch where our own priorities were in flux. I'd hire him again without hesitation.

Kathmandu, Nepal - 6:33 pm local time
I build RAG pipelines and LLM systems that make it to production — not demos that stall. AI that retrieves accurately from your own data, and integrations built to reduce cost, not inflate it. Top Rated | 100% Job Success | 104+ projects delivered.

I'm a Python and AI engineer with 7 years building production systems end to end: RAG pipelines grounded in internal documents, AI agents that automate real workflows, trading platforms with real-time data feeds, and full-stack applications taken from empty repo to deployment.
SELECTED RESULTS

- Cut GPT inference cost 41% via a custom RAG architecture eliminating redundant API calls — no accuracy loss
- Reduced API latency 72% through an async redesign on FastAPI + Redis
- Sustained 12,000 requests/min at 99.99% uptime after decomposing a Django monolith into microservices — zero-downtime migration
- Processed 2M+ events/day at 37ms average latency on containerized infrastructure with PostgreSQL sharding
- Compressed release cycles from 2 days to 2 hours with GitHub Actions CI/CD
- Cut AWS spend 35% through infrastructure rightsizing

WHAT I BUILD

RAG systems that retrieve accurately from your data. AI agents automating real workflows. Cost-aware LLM integrations. Plus the full stack around them: Python backends, React/Next.js frontends, REST APIs in Django or FastAPI, real-time WebSocket features, cloud deployment on AWS/Azure/GCP, and CI/CD pipelines.

THE STACK

AI/LLM: GPT, Claude, Gemini, LangChain, LlamaIndex, RAG, AI Agents, pgvector, Pinecone, Qdrant
Backend: Django, DRF, FastAPI, Flask, Celery, AsyncIO, WebSockets
Frontend: React, Next.js (App Router), TypeScript, Tailwind CSS
Databases: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Supabase
DevOps: AWS, GCP, Azure, Docker, Kubernetes, Nginx, GitHub Actions
Linux: Ubuntu, Debian, VPS hardening, SSL, Systemd

If you're shipping an AI feature or need a backend that holds up in production, send a message or an invite. I reply within a few hours.
