Agentic AI Engineer | LangChain, RAG Chatbots & n8n Automation
100% Job Success
4.6  (109 reviews)
Noida, India - 2:52 pm local time
I build agentic AI systems that run in production, not demos.
LangChain pipelines, RAG chatbots, and n8n automations that hold up under real users and real load.

149 completed Upwork projects. 2,790 hours. 100% Job Success Score.

Fifteen years co-founding and running iByte Infomatics, shipping SaaS products of my own - so I scope your project the way a product owner would, not the way a contractor does.

WHAT I BUILD

→ Agentic AI systems - LangChain, OpenAI API, Anthropic Claude API. Multi-step agents that take action and call tools, not chatbots that only answer.

→ RAG chatbots over your own data - retrieval, chunking, evaluation, and deployment into the channels your customers already use.

→ Automation pipelines - n8n, Make, Zapier. Manual workflows replaced with observable, reliable automations that don't break silently.

→ Python backends behind the AI - FastAPI, Django, PostgreSQL, Supabase, Docker. Built to scale from day one.

SELECTED WORK

- AI legal research assistant - cut research time by 70% for a legal team

- Slack Memory Bot - Symfony 7 + Anthropic API system that captures architectural decisions from Slack threads and surfaces them as reviewable Markdown

- LLM audit for PhD research - statistically rigorous audit of a GPT-4o entropy experiment. Client: "an expert Data Scientist"

- CabinMeet - offline-first meeting notes SaaS (React Native + Node.js + Docker). Runs speech recognition on-device and routes only summarization to Gemini Flash, holding infrastructure cost near zero at early scale.

- No-code SaaS platform for Social Media Management - full system architecture and build

WHAT CLIENTS SAY

My most recent projects have averaged 4.9 stars.
Upwork's own feedback tags on my work: Clear Communicator (30), Collaborative (28), Reliable (27), Committed to Quality (24).

HOW I WORK

I scope before I build. You get a written breakdown of approach, timeline, and what "done" means before any code is written - so there are no surprises at delivery, and no scope arguments later.

I work from India (IST) with deliberate overlap into US mornings for calls and fast turnarounds.

TECH STACK

Send me your project details and I'll come back with a clear breakdown of approach, timeline, and cost - including an honest answer on whether I'm the right fit.
