I'm providing the complete UI design and all necessary data fields and am now looking for support with the technical aspects. Specifically, I want to create a price comparison portal that automatically retrieves prices and product details from around ten target websites, aggregates them, and presents them in a clear and organized way. What's already available: • Finished layout mock-ups (desktop + mobile) • List of shops to be scraped, including the desired data points • Basic logic for sorting and filtering, documented as pseudocode Your task: • Develop a robust web scraping script (preferably Python + BeautifulSoup / Scrapy or similar tools). • Extract price, availability, product name, and shipping costs (if applicable). • Store the data in a structured format (e.g., MySQL, PostgreSQL, or JSON → you can suggest a suitable solution). • Provide an API or an easy-to-integrate data endpoint so I can easily connect the front end. • Implement an update interval (cron job or scheduler) to ensure prices are updated daily. • Build in simple error logs and duplicate checks to guarantee data quality. Acceptance Criteria 1. All ten shops are retrieved without manual intervention. 2. Endpoint response time remains less than 1 second for 100 products. 3. The scraper doesn't completely abort when layout changes occur, but instead logs the affected fields. 4. The setup instructions can be executed in a fresh environment in less than 30 minutes. If you have experience with anti-bot bypassing (CAPTCHAs, rate limits) and scalable scraping architectures, please mention it briefly. I look forward to your technical assessment and a rough roadmap for implementation.

Thanks for outlining your needs — it’s clear you already have the design and data structure ready, and now the real challenge is the technical layer: reliable price extraction, accurate data aggregation, and smooth presentation. Most comparison portals fail because scraping breaks often, data formats vary across sites, and updates don’t sync cleanly. My focus will be to build a backend that solves these issues long-term, not just for launch. I’ll implement a robust scraping and data-collection system using a mix of REST/API calls (if offered) and smart crawling with rotation, rate-control, and fail-safe mechanisms so the ten target websites can be monitored without getting blocked. Each dataset will be normalized, cleaned, and mapped to the fields you’ve already defined, ensuring every product displays consistent pricing, specs, and availability. From there, I’ll build the comparison logic and API layer that your UI can plug into seamlessly, returning fast and organized results exactly in the formats your screens expect. You’ll also get a simple admin or monitoring panel to track scrape success, logs, and update cycles — so you’re in control even after delivery. If this approach aligns with your vision, I can begin immediately. Let’s discuss the target websites and update frequency so I can plan the best architecture for you.

Hi, there. A price-comparison portal usually breaks down when sites change layouts or block bots, so my first goal is to build you a scraper that stays stable, adapts quickly, and logs issues instead of failing. Since you already have the full UI and data structure ready, I can jump straight into the technical core and make it all work smoothly behind the scenes. Think of this as giving your front end a steady, always-updated fuel source without you babysitting anything. I’ll build a clean, scalable scraping system (Python + Scrapy/BS4) that pulls prices, stock, product names, and shipping from all 10 shops, stores everything in a structured DB (MySQL/PostgreSQL), and exposes a fast API that your front end can plug into instantly. Daily updates via cron, duplicate protection, error-aware parsing, and <1s response time for 100 products won’t be a problem. And yes—I've handled CAPTCHAs, rate limits, rotation proxies, all that fun stuff. Happy to map out a quick roadmap once you’re ready. Warm regards.

Ready to build a reliable price-comparison backend that scrapes ~10 shops, normalises prices & shipping, stores results, and serves a fast API — resilient to layout changes and easy to deploy. We’re a team of 62 professionals with 9+ years building scrapers, ETL pipelines, APIs, and scalable data stores. Here's how we can help: Python scraper stack (Scrapy or Requests+BeautifulSoup) with modular spiders per shop Extract price, availability, product name, shipping; normalise & dedupe before storage Store results in MySQL/Postgres (or JSON for simple setups) with schema suggestions Expose a REST API endpoint for your frontend with <1s response tuning (indexes, caching) Scheduler/cron for daily updates, incremental fetches, and retry logic Error logging, field-level fallback on layout changes, and duplicate-checking rules Lightweight anti-bot strategy notes (rate-limiting, rotating proxies, headless fallback) and deployment instructions (Docker) Quick questions to scope work and meet acceptance criteria: Can you share the list of 10 target shops (any login/CAPTCHA pages)? Preferred DB (MySQL or Postgres) and hosting (self-hosted Linux, cloud)? Expected product volume and peak reads per minute for API sizing? Do you want a Docker-based one-command setup and a 30-min install script for a fresh environment? If that looks good I’ll provide a brief roadmap, milestones, and an ETA.

Dear Hiring Manager, Thank you for the clear breakdown of your requirements. With your finalized UI and data spec in place, I can focus fully on designing a robust, maintainable scraping and aggregation backend for your price comparison portal. ➡ Design and implement Python-based scrapers (Scrapy/Requests + BeautifulSoup) for all ~10 target shops ➡ Extract price, availability, product name, and shipping costs with structured, normalized output ➡ Store data in a suitable structured backend (e.g., PostgreSQL/MySQL or JSON-based store) based on your hosting ➡ Expose a clean API/data endpoint (REST/JSON) tailored to your front-end’s expected payloads ➡ Implement daily updates via cron/scheduler with configurable intervals per shop ➡ Add duplicate checks, basic validation, and error logging so layout/API changes are clearly surfaced ➡ Ensure scrapers degrade gracefully: skip failing fields, log issues, but keep the overall job running ➡ Optimize queries and API responses to keep response time under 1 second for 100+ products ➡ Provide clear setup documentation so a fresh environment can be configured in under 30 minutes I also have experience handling anti-bot measures (rate limiting, rotating headers/IPs, backoff strategies, and CAPTCHA-aware flows) and can factor this into the architecture. I will share a concise technical roadmap covering phases: scraper design, storage schema, API layer, scheduling/monitoring, and final handover. Best Regards, Mayank Saluja
