Description

🛠 Project Overview:

We are building a browser-based or hybrid SaaS tool for Optical Character Recognition (OCR) using Tesseract.js or a similar OCR solution in JavaScript. The tool should offer:

  • Maximum possible OCR accuracy
  • Support for handwritten and printed text
  • OCR support for the following languages:
  • English, Spanish, Russian, Dutch, Italian, Portuguese, Indonesian, German, French, Korean, Danish, Czech, Swedish, Polish, Romanian, Thai, Vietnamese, Turkish, Japanese, Chinese, Georgian, Finnish, Arabic

Note: The solution must not use heavy machine learning models, and should rely on Tesseract and image preprocessing optimizations.




💡 Nice to Have:

  • Experience working on Tesseract (https://tesseract.projectnaptha.com/)
  • Understanding of handwriting OCR challenges


📩 Deliverables:

  • High-performance, accurate OCR module (React or plain JS)
  • Tuning and configurations for all listed languages
  • Well-documented, clean codebase and integration guide


❓ Questions to Answer in Your Application:

  1. Have you previously worked with Tesseract.js? Please provide code samples or GitHub links.
  2. What strategies would you use to optimize OCR accuracy in the browser?
  3. What are Tesseract’s limitations with handwritten text, and how would you mitigate them without ML?
  4. Have you ever worked on image preprocessing (e.g., binarization, noise reduction)? If yes, how?
  5. What challenges do you foresee in implementing this OCR tool purely in the frontend?


Responsibilities

✅ Responsibilities:

  • Implement Tesseract.js-based OCR in a React or Next.js frontend
  • Configure and optimize Tesseract for multi-language and handwriting scenarios
  • Efficiently load large traineddata language files in-browser
  • Build a clean, modular OCR interface for integration into our SaaS product
  • Apply image pre-processing techniques to improve OCR accuracy (grayscale, thresholding, etc.)
  • Deliver performance optimizations for speed and accuracy
  • Work collaboratively and communicate technical decisions clearly


Requirements

🧠 Required Skills:

  • Strong experience with JavaScript/TypeScript
  • Proficiency with Next.js or React.js
  • Hands-on experience with Tesseract.js
  • Familiarity with Tesseract configuration (psm, oem, etc.)
  • Knowledge of image processing basics (e.g., sharp.js, canvas)
  • Performance tuning and efficient frontend architecture


Benefits

  • Longterm Project
  • Competitive Salary
  • Learning Environment
