AI Document Processing | PDF, OCR & Invoice Extraction | IDP

I help companies turn messy documents into structured, usable data. Most of my work is around document automation, OCR, and data extraction from PDFs, invoices, lab reports, contracts, and email attachments — the kind of documents where standard tools often fail.

Most clients find me after something partly working stops working. The extraction script handled 80% of documents fine, then broke on the rest and nobody can explain why. That’s what I fix.

My longest engagement ran two years on retainer — a water consultancy processing lab reports across 10+ changing layouts. Cut their manual data entry by 75%. Based in Durham, UK.

“Thanks to Subhajit’s work, we are saving countless hours having to manually enter results into our own template.”
