You will get AI document processing app to extract and validate data with LLM

Project details
Most document work is not hard. It is just endless. Someone opens a PDF, reads the fields, types them into a system, and does it again two hundred times.
I build an app that reads the document for you. It turns scans and PDFs into clean text, then an LLM pulls out the fields you care about. Invoice numbers, dates, line items, totals, whatever your process runs on.
Then it checks its own work. Every field gets a confidence score. Anything the model is unsure about goes to a human review queue instead of quietly landing in your system wrong. That one step is the difference between automation you trust and automation you have to babysit.
You can also ask questions across the whole document set. Which vendor billed twice last quarter. Where that clause sits. The app searches your own documents and answers from them.
I built this for a finance team running invoices end to end into their accounting system. That case study is in my portfolio.
Tell me what your documents look like and I will tell you honestly what is realistic.

Test engineer for end to end automated testing of entire SaaS Application (with some manual testing)
Indu has worked for us on a full-time basis for ~7 years and I have nothing but great things to say about her. She has been dedicated, hard-working and super diligent on all the automated testing we have thrown her way. She worked hand in hand with the development team and customer support team and our software was all the better for it. The team had a wonderful relationship with her; she is friendly, supportive, inquisitive, experienced, knowledgeable and what everyone would want in a contractor. Unfortunately, we have transferred our customer base to a third party company and we have had to terminate her contract (and all others) with us. I would not hesitate one second to re-contract with Indu should the opportunity arise again. I wish her all the best, and we will miss her:(

Most of my clients already use CRMs, ERPs, spreadsheets, or support tools but still rely on people to move data, read documents, draft replies, and chase follow-ups. That's where I come in: I turn those manual, repetitive tasks into AI-powered systems that are accurate, monitored, and cost-controlled.
What I build
• AI applications - document extraction (OCR + GPT-4o/Claude), per-field confidence scoring, human-in-the-loop review
• RAG pipelines - vector search (pgvector / HNSW), embeddings, and knowledge bases grounded in your data
• AI agents & MCP tools - custom agents and copilots for ops, finance, and support teams
• Workflow automation - Make & n8n, multi-step, error-handled, and monitored
• Enterprise API integrations - ERP/CRM/finance systems (Sage Intacct, HubSpot, SharePoint), REST, webhooks, SQL
Recent work & results
• AI invoice-processing app - PDF → GPT-4o extraction + RAG over 50,000+ historical documents, auto-coding invoices to the right accounts with confidence scoring → eliminated hours of manual AP coding, with a full audit trail.
• AP payments → ERP suite - 30+ orchestrated Make scenarios syncing payments, bank feeds, and reconciliation into Sage Intacct + SQL across multiple entities → a near-hands-off finance back office.
• AI content & monitoring engine - n8n + LLMs drafting on-brand content and intelligence across 7+ brands, synced to Notion/Slack → hours of manual work turned into a reviewable AI pipeline.
• Custom AI agents & MCP tooling - agentic tools that connect LLMs to live data sources for non-technical teams.
Why teams keep rehiring me?
I run automations like software - Git-backed versions, error alerting, credential monitoring, and clear documentation for handover. I'll also tell you honestly what's worth automating and what isn't.
Tools I work with
AI/LLMs: OpenAI, Claude, LangChain, RAG, AI Agents, MCP
Automation: Make, n8n, Power Automate, Zapier
Data/Integration: REST APIs, Webhooks, PostgreSQL, pgvector, SQL, Python
Platforms: HubSpot, Airtable, Notion, Slack, Google Workspace, SharePoint/Office 365
Let's talk if you want automation that actually works, measurable business impact and someone who can own it end-to-end. Message me with what you're trying to automate. I'll give you a clear, honest recommendation.
