Paid client work · Infrastructure review

AWS Terraform and Docker pre-deployment review

Reviewed 13 Terraform files and a Dockerfile before the client's first deployment. The paid two-hour engagement covered correctness, security, cost and first-apply risks.

Delivered written findings, including a migration script missing from the runtime image. The engagement was a review only, with no Terraform plan, code changes or deployment.

Terraform pre-deployment review

“Rajiv reviewed a Terraform configuration that had never been applied, before I ran it for the first time. The report was super precise, verifiable and more helpful than I expected. Every finding pointed at a file and a line, with the reasoning behind it rather than a tool dump, which is what I had asked for. So a very very helpful session and highly recommended”

WhatsApp AI Customer Support Agent

“Rajiv built us an AI support agent for WhatsApp that handles our repetitive customer questions automatically: order status, returns, shipping times, product info, opening hours. It uses RAG to pull answers from our knowledge base, so responses are accurate and match our actual policies, not generic replies. When a query is too complex, it hands off to a human agent with full context, and every conversation gets logged in Google Sheets. The whole thing runs through n8n connected to WhatsApp Business API, and we can add new FAQs ourselves without needing a developer. Rajiv walked us through the setup clearly, and communication was fast throughout. Highly recommend him for n8n, WhatsApp automation, RAG, and customer support AI projects.”

AI Voice Receptionist for Missed Calls

“Rajiv delivered exactly what we needed. We were losing leads every time we missed a call during busy hours and after closing. Now, an ElevenLabs voice agent picks up via VAPI, sounds completely natural, answers questions about our services and pricing, and books the caller straight into Google Calendar without us lifting a finger. What impressed us most was how natural the call flow feels; callers actually stay on the line and book. Every call ends with an instant Twilio SMS to my phone with the caller's name, what they needed, and whether they booked or left a message. The whole workflow runs on n8n, connected to our Twilio number and tested with real calls. Rajiv walked us through updating the script ourselves without touching any code. Will definitely hire again.”

AI Video Ad Generator with RAG and AWS

“Rajiv built us an AI automation system in n8n that turns a product idea into a finished AI video. It uses RAG to pull from our brand documents, writes the ad script, generates the AI video, and saves everything to AWS S3 with version control. He had already built similar AI video automation workflows using RAG and n8n, which gave us confidence in his expertise. The final solution matched our requirements perfectly, and I highly recommend him for AI video generation, RAG, n8n, and AI automation projects.”

AI Content Generation and Auto-Publishing

“Rajiv is a pleasure to work with. He demonstrated good technical expertise in building our AI content generation and auto-publishing system using n8n and AI models. His knowledge of automation, AI workflows, and n8n was evident throughout the project. I'm very happy with the quality of his work and would highly recommend him to anyone.”
