Amit Pathak

I’m a Senior Software Engineer with 11+ years of experience building PDF processing, OCR, document automation, and high-performance systems. I specialize in PDF library customization, Document AI, performance optimization, and large-scale document work.

In my Upwork work (Freelancer, Feb 2021–Present), I developed PDF parsing and OCR-driven automation systems that improved extraction efficiency by 20%. I also built data visualization tools to support faster decision-making, improving insights by 15%, while applying data cleaning and parsing techniques to handle document-derived data more efficiently.

At ARC Document Solutions (Technical Lead & Senior Software Engineer, Jul 2014–Jul 2020), I led development and R&D across PDF applications, customized libraries, core product modules, 3D modeling applications, and microservices deployed in Docker containers. I finalized and built features like PDF markup, measurement, and PDF document security, plus a multi-threaded PDF thumbnail viewer that reduced loading time by 11% versus Adobe for large architectural drawing PDFs.

I’ve also driven major performance and cost wins—migrating core services from .NET to Scala for a 5x increase in data processing speed, cutting licensing costs by 100% through open-source customized libraries, and reducing EC2 instances by 50% via containerized microservices written in .NET and Python. I bring a deep, source-level mindset to systems engineering—whether it’s patching PDF engines, optimizing rendering pipelines, or building end-to-end conversion and OCR workflows.
