03 / AI & automation

Behind
the scenes

Most of this work lives behind company walls, so here's what each system does and how it's put together.

  • 01

    −60%

    manual processing time

    AP Automation & OCR

    Accounts-payable automation that reads incoming invoices with OCR, extracts and validates the data, and posts it into finance systems. Async workers with locking and retries keep every record consistent.

    Invoice → OCR → Validation → ERP

    Python · Django · OCR · Redis · Worker Queues

  • 02

    +40%

    operational efficiency

    ERP & E-commerce Integrations

    Automations connecting ERPs with e-commerce stores and the rest of a business's software, syncing orders, products and financial data through n8n, Zapier, webhooks and custom APIs.

    Store → Webhook → n8n / Zapier → ERP

    n8n · Zapier · Webhooks · REST · GraphQL · SOAP

  • 03

    OCR + NLP

    documents and live camera

    Document Ingestion & Product Vision

    AI ingestion for invoices and documents, plus camera-based detection of products, allergens and attributes. Tesseract and regex pull structured fields, GLiNER extracts entities, and custom Hugging Face models cover the domain-specific cases.

    Camera / PDF → Tesseract + Regex → GLiNER → HF Models

  • 04

    RAG

    answers grounded in company data

    Retrieval-Augmented Assistants

    LLM assistants that answer questions from a business's own documents. Content is chunked and embedded, the most relevant passages are retrieved for each question, and the model answers from those sources instead of guessing.

    Docs → Chunk + Embed → Vector Search → LLM

    Python · LLMs · Embeddings · Vector Search · OpenAI API

04 / Live demo

Invoice extraction,
in your browser

OCR finds every text segment, a regex pull and an NLP pull read the fields, and table detection rebuilds the line items, then checks the maths. Works with photos, scans and PDFs. Nothing is uploaded.

1. Pick an invoice
