Data Extraction & Automation Demo

@vishal1145

Your OCR pipeline will fail if you're processing scanned PDFs without preprocessing - blurry images and skewed text drop accuracy below 60%, which makes the extracted tender data unusable. I've built similar government portal scrapers where document quality varied wildly, and without proper image normalization, you'll spend more time fixing bad extractions than building features. Quick question - are you scraping portals that use JavaScript-heavy pagination or CAPTCHA protection? And what's your expected document volume per day - 100 or 10,000? This determines whether you need Scrapy's async architecture or if Selenium's simpler but slower approach works for the demo. Here's the architectural approach: - SCRAPY + SELENIUM: Hybrid scraper that uses Scrapy for static pages and Selenium only when portals require JavaScript rendering, reducing processing time by 70% compared to pure Selenium. - FASTAPI + CELERY: Queue-based async processing where Celery workers handle OCR jobs independently from the crawling pipeline, preventing bottlenecks when documents pile up. - POSTGRESQL + FULL-TEXT SEARCH: Implement GIN indexes on tender descriptions and metadata fields so search queries return results in under 100ms even with 50K records. - TESSERACT OCR + OPENCV: Preprocess scanned PDFs with deskewing and contrast enhancement before OCR to boost accuracy from 60% to 92% on government documents. - REACT + DOCKER: Containerized dashboard with real-time crawl status using WebSockets, so you can monitor failures without SSH-ing into servers. I've delivered 4 similar scraping systems for procurement platforms where duplicate detection and corrigendum tracking were critical. The 10-15 day timeline is tight but doable if your portal list is finalized and you're not expecting AI-based entity extraction in this phase. Let's schedule a 20-minute call to walk through the portal structures and confirm OCR requirements before I commit to the build.

@sakshigweb

Hi there, Demo-first is the right call — validate the crawling pipeline and dashboard before committing to production infrastructure. We know how to build a demo that's presentable enough to prove the concept and structured enough to scale from cleanly. Here's what we deliver within your ₹25,000 demo scope: - Crawler: Automated crawling with dynamic portal handling, pagination, session management, duplicate detection, and basic corrigendum tracking — Python + Scrapy/Selenium - Extraction: Structured metadata normalization, queue-based async processing via Celery + Redis - OCR: Tesseract integration for scanned document support - Dashboard: React-based responsive UI — search, filters, listing tables, monitoring cards, detail views - Admin Panel: Source management, crawl monitoring, activity logs — role-based access - Delivery: Full source code + Dockerized deployment + technical documentation Stack: Python + FastAPI + PostgreSQL + Redis + React — matches your preferred architecture exactly. Architecture is modular from day one so production scaling phases don't require rebuilding the demo foundation. One question: which portal type should the demo crawler target first — government eProcurement, PSU, or municipal sources?

Hi! Read the brief — demo/validation build for crawling + structured extraction + OCR + dashboard, fixed at ₹25,000 in 10–15 days. That's a stack we ship in regularly: FastAPI/Python workers, Scrapy + Selenium for dynamic portals, Postgres for normalized metadata, React.js admin dashboard, all wrapped in Docker. Recent build: a corrigendum/tender tracker that crawled multiple state portals, deduped via content hashes, and surfaced updates in a React dashboard with search and filters. OCR via Tesseract for scanned PDFs. Can deliver the demo scope inside your timeline, source + docs + deployment included. Ping me and we can quickly align on portal list and confirm scope before kickoff. — Rohan, APIE TECH

@songpow7

Hello, I can build the demo/validation version with a controlled MVP scope for 10–15 days. Proposed scope: 1. Python/FastAPI backend + PostgreSQL schema for normalized extracted records. 2. Crawler prototype for 1–2 agreed source portals using Scrapy/Selenium depending on portal behavior. 3. Structured extraction with basic duplicate detection and update/corrigendum tracking. 4. Basic OCR path for scanned documents. 5. Demo-level async queue/status tracking. 6. Simple dashboard/admin view for search, filtering, record status, and metadata. 7. Docker Compose, source code handover, deployment notes, and documentation. I would keep enterprise scaling, distributed crawling, and advanced AI workflows outside this first demo so the validation version stays realistic. My background is Python/FastAPI automation, workflow orchestration, structured data processing, API/tool integration, and reliability-focused automation systems. I focus on making the demo easy to inspect, run, and extend. Suggested milestones: crawler + schema prototype, then OCR/dashboard, then Docker/docs/handoff. I work best with clear written requirements, milestone-based delivery, and concise async updates. Best regards, Songpo Wang

@RubinTh

I've built procurement intelligence crawlers and admin dashboards at exactly this kind of proof of concept scale, validating architecture before committing to production, and the scope you've described maps closely to work I've delivered before. For the demo I'd use Python with Scrapy and Playwright for dynamic portals, Celery for async queue management, and PostgreSQL for structured metadata storage. OCR would be handled via Tesseract with a pre processing layer for scanned PDFs. Duplicate detection would run on a hash of normalised title, source, and date fields. The dashboard built with React and a FastAPI backend would give you search, filtering, corrigendum tracking, and basic monitoring, all within the Rs 25,000 scope. Source code, deployment assistance, and documentation are standard deliverables for me. I'd target 10 days for the demo, leaving buffer for your QA and feedback round before sign off. This is a sensible way to validate before scaling and I'll build it cleanly enough that the demo codebase can grow into production rather than being thrown away. Prices are negotiable.

@sergegustave

Hello, I’m very interested in your project, especially because it combines automation, data extraction, OCR, and dashboard management, which are areas I already worked on. I’m a full-stack developer with 3 years of experience. I mainly work on web applications with Symfony and React, as well as APIs and automation systems using Python/Django. I also have experience building automation workflows and multi-agent systems with n8n. For the demo/MVP phase, I can help with: crawling workflows structured data extraction OCR integration duplicate detection logic admin dashboard development search and filtering features deployment assistance and technical documentation I’ve also worked on projects involving data processing and visualization with a structured approach on both architecture and automation. Since this project is focused on a validation/demo version and not yet enterprise-scale infrastructure, the scope seems realistic for building a solid functional MVP within the expected timeline. If needed, you can send me more details about: the portals or sources to crawl the type of documents involved OCR requirements and the main priorities for the demo version Best regards, Serge
