You will get Automated Invoice Processing Pipeline — AI + n8n + Google Sheets
Project details
Built an end-to-end invoice processing pipeline that eliminates manual data entry. A PDF invoice is uploaded, n8n extracts the text, AI parses all key fields (vendor, client, amounts, line items, dates, payment terms), and structured data is written to Google Sheets automatically. Processes any invoice format, handles multiple currencies, and reduces processing time from 5 minutes per invoice to under 10 seconds. Tech stack: n8n, AI/LLM API, Google Sheets, Python, REST APIs. Delivered with Loom video walkthrough.

About Sergio
Business Process Automation & AI Solutions | n8n, Make, Python | 10+ Y
Buenos Aires, Argentina - 5:19 am local time
With 10+ years leading tech teams and managing complex projects in the media industry, I understand how operations actually work — and where automation creates real impact.
What I do:
→ Build automated workflows that replace manual, repetitive processes (n8n, Make, Zapier)
→ Create AI-powered document processing pipelines (invoices, contracts, CVs, reports)
→ Design dashboards that summarize your data with AI-generated insights
→ Audit your current processes and identify the top automation opportunities
My approach is simple: I listen first, understand your business, then deliver a working solution — not a deck full of promises. Most projects are fixed-price with delivery in 1-2 weeks.
Tools & stack: Python, SQL, Google Sheets (advanced), REST APIs, n8n, Make, AI/LLM integrations, Streamlit, Retool.
I communicate clearly via messages and deliver video walkthroughs (Loom) of every solution so you see exactly how it works.
Let's talk about what's eating your team's time. I'll tell you if I can help — and if I can't, I'll tell you that too.
