Just built an end-to-end invoice automation workflow that turns a manual billing process into a fully automated system.
How it works:
π Detects new invoices uploaded to Google Drive
π Extracts data from PDF invoices
π€ Uses AI to structure and process the information
π Automatically records invoice details in Google Sheets
π§ AI Agent generates a clear billing notification
π§ Sends the notification directly to the Billing Team via Gmail
Tech Stack:
n8n β’ Google Drive β’ Google Gemini β’ Groq β’ Google Sheets β’ AI Agents β’ Gmail
The impact:
β Reduces manual data entry
β Minimizes human errors
β Speeds up invoice processing
β Keeps billing records organized
β Automatically notifies the right team
Iβm focused on building practical AI automation systems that eliminate repetitive work and help businesses operate more efficiently.
If a business process involves repetitive manual steps, thereβs probably a way to automate it. β‘
An AI-powered phone receptionist built for real estate agencies that answers inbound calls, qualifies leads in real time, and books showings directly to Google Calendar β all within the call itself, with no manual follow-up required.
The problem: Real estate agencies routinely lose leads to missed calls β after-hours inquiries, calls during showings, or overflow during busy periods. A slow callback often means the lead has already moved on to a competitor.
What it does:
Answers every call instantly, 24/7
Naturally qualifies the caller (buy/sell intent, area of interest, showing vs. agent call)
Collects contact details and preferred timing conversationally
Checks real-time calendar availability before booking
Prevents double-bookings and duplicate entries automatically
Confirms the appointment out loud before ending the call
Built with: Retell AI (conversational voice layer), n8n (workflow automation and business logic), Google Calendar API (scheduling)
Available for: Custom builds for real estate agencies, brokerages, or property management companies looking to stop losing leads to missed calls
Your HR team shouldnβt spend hours doing repetitive hiring tasks that AI can automate.
Every day, companies deal with repetitive processes β collecting information, reading job applications, writing emails, selecting documents, updating spreadsheets, and keeping everything organized. π
I recently built an AI-powered job application automation to demonstrate exactly how these repetitive workflows can be automated. π€
Hereβs how my system works:
Job Post β Data Extraction β Gemini AI β Personalized Application β Job-Based Routing β Resume Selection β Gmail β Tracking βοΈ
The workflow automatically:
πΉ Extracts the email, company name, and job title from a job post
πΉ Uses Gemini AI to generate a personalized application email
πΉ Classifies the job based on the role
πΉ Automatically selects the appropriate resume
πΉ Sends the application through Gmail with the resume attached π
πΉ Updates the application information in Google Sheets π
I built this using Make.com, Gemini AI, Gmail, Google Sheets, and Google Drive.
But the bigger idea behind this project is business process automation. π
The same automation approach can be adapted to help companies reduce repetitive work across recruitment, lead management, customer communication, reporting, data processing, and other business workflows.
If a process is repetitive, rule-based, and time-consuming β thereβs a good chance it can be automated. β‘
I built an AI-powered Instagram chatbot using n8n, connecting AI, automation, memory, APIs, and knowledge retrieval into one complete workflow.
The chatbot can:
Understand incoming Instagram messages
Maintain conversation context using memory
Retrieve relevant information from a knowledge base
Generate intelligent responses with OpenAI
Automatically respond through the Instagram API
Tech Stack
n8n
OpenAI Chat Model
AI Agent
Pinecone Vector Store
Simple Memory
Instagram API
Webhooks
Switch & If nodes
This project was a great hands-on experience in building an end-to-end AI automation workflow and connecting multiple services to create a practical conversational system.
For me, the key takeaway was that effective AI automation is more than just an AI model, it's about connecting the model with the right data, memory, APIs, and workflow logic.
