About this role
OCR, Node.js, AWS Textract · We are building an automated evaluation engine for handwritten student exam papers. We need an experienced AI/Full-Stack engineer to develop an end-to-end pipeline in Node.js that accepts scanned handwritten PDFs, performs OCR/HTR to map word-level coordinates, evaluates the content using Multimodal Vision LLMs, and programmatically renders high-precision visual annotations, margin callouts, checkmarks, and pointer arrows directly onto the output PDF.
