Hi there, I have hands-on experience building OCR pipelines and web-based OCR services, particularly for financial documents. I’ve benchmarked multiple open-source OCR engines, including Tesseract, PaddleOCR, MMOCR, and EasyOCR, and selected high-accuracy pretrained models based on real-world performance. Using these models, I developed a web service to reliably process and extract data from financial documents. This practical experience allows me to design OCR solutions that balance accuracy, performance, and scalability. I’d be happy to work on your project and discuss the requirements including the data you have in more detail. Looking forward to your response. Thank you, Jijo

@arbu1499

This is exactly the kind of document-processing problem I specialize in—precision-first extraction, OCR only when justified, and cost-aware backend design. I’ve built production pipelines that differentiate native text vs mixed PDFs at page level, generate true page-coordinate bounding boxes, and integrate cleanly with PDF viewers for accurate highlights. I’m comfortable auditing existing architectures, hardening Firebase/GCP backends, and designing OCR strategies that avoid unnecessary Tesseract usage while scaling safely. I can step in immediately and drive this milestone-by-milestone to a stable, efficient system. Looking forward for your positive response in the chatbox. Best Regards, Arbaz Ali

✋ Hi there. I can build a precise, cost-efficient document processing backend that handles PDFs and other formats while enabling accurate text highlights with bounding boxes. ✔️ I have solid experience with document parsing, PDF processing, OCR optimization, and production-ready backends. In a recent project, I implemented a system that extracted native text, selectively applied OCR, and returned bounding boxes for frontend highlights, all while keeping operational costs low and performance high. ✔️ For your project, I will audit your current architecture, design a scalable OCR and extraction pipeline, handle mixed document types, and implement bounding boxes for text highlights. I will also address authentication, upload stability, backend protection, rate limiting, and logging to ensure robust, secure operations. ✔️ I will optimize performance, reduce cold starts, handle errors gracefully, and provide clear documentation and monitoring strategies for long-term reliability. Let’s chat so I can review your current setup and start planning the implementation of this precision-focused document processing system. Best regards, Mykhaylo

@masiahm4

Hi! I’m a full‑stack developer with 5 years in Python/JS delivering production document systems and automations (invoice processing, AI agents, custom CRMs). I’ll help you ship a precise, low‑cost document chat experience. Business outcomes I drive: - Accurate, zoom‑safe text highlights via true page‑coordinate boxes. - OCR cost reduction by strict per‑page detection; zero OCR on native text; low‑cost vision only for fully scanned pages. - Robust backend: stable auth/upload, rate limits, logging, and abuse prevention to protect margins. - Performance tuning to cut cold starts, errors, and latency. Plan: - Milestone 0: 1–2 day audit to surface risks, costs, and a pragmatic OCR + security design. - Then smart extraction, highlights, P0 fixes, protections, and reliability improvements—mapped to measurable KPIs (accuracy, p95 latency, cost/doc). Could you share your current stack (cloud, PDF viewer, storage) and a few representative documents? Happy to jump on a quick call.
