I need a developer to build a fully-functional aggregator that can collect information from Websites, APIs and RSS feeds, normalise the data, and make it available through a single, well-documented endpoint or database. Scope of work • Set up reliable crawlers/scrapers for selected websites, incorporate any available public or private APIs, and subscribe to RSS feeds. • Implement scheduling, rate-limiting and error-handling so each source is polled responsibly without missing updates. • Store the aggregated output in a structured format (SQL, NoSQL or flat-file; I’m open to your recommendation) with clear metadata for source, timestamp and content type. • Expose the data via REST or GraphQL, and include a minimal dashboard or logfile that lets me monitor fetch status, failures and new items in real time. • Deliver clean, well-commented code plus a short README explaining how to add new sources and deploy the solution on a typical cloud VPS. Acceptance criteria 1. All configured websites, APIs and RSS feeds are queried automatically on the defined schedule. 2. Duplicate entries are detected and suppressed. 3. A single JSON response returns merged results in under one second for a 100-item request on standard hosting. 4. Setup instructions let me reproduce the build from scratch in less than 30 minutes. Feel free to choose the tech stack—Python (Scrapy, BeautifulSoup, FastAPI), Node.js (Cheerio, Axios, Express) or something comparably mainstream—as long as you specify versions and any open-source libraries you use. Please include a brief outline of your approach, the tools you prefer, and an estimated timeline.

Hello, I’d love to help you improve your website’s organic visibility on Google and Bing with a structured, data-driven SEO approach. I understand your current challenge is plateaued growth and the need to start from the foundation—proper keyword research, competitor analysis, and identifying realistic ranking opportunities before making any changes. I’ve worked on SEO projects where rebuilding the keyword strategy and aligning on-page structure led to consistent ranking improvements and traffic growth. My approach would be: • Discovery & Research: Full site audit (technical + content), competitor analysis, and keyword research using tools like SEMrush, Ahrefs, and Google Search Console to identify high-potential keywords • On-Page Optimization: Optimize titles, meta tags, headings, internal linking, and content while ensuring Core Web Vitals and page speed remain strong • Off-Page Strategy: White-hat link building (guest posts, niche directories, outreach) to gradually improve domain authority • Tracking & Reporting: Setup/refine Google Analytics, Search Console, and Bing Webmaster Tools with clear monthly reports and actionable insights I focus on measurable improvements rather than guesswork, with early ranking movement typically visible within 4–6 weeks depending on competition. I’m ready to start immediately and can begin with a full audit and keyword strategy as the first step. Warm regards, Ritu

I build exactly this kind of system — multi-source data aggregation with scheduled polling, normalization, and a clean API on top. My approach: - Python + FastAPI for the REST layer (fast, async, well-documented out of the box) - Scrapy/BeautifulSoup for website crawlers, httpx for API sources, feedparser for RSS - APScheduler for polling with per-source intervals and rate limiting - PostgreSQL for structured storage with source/timestamp/content metadata - SHA-based deduplication so duplicates never make it to the DB - Simple status dashboard showing last fetch time, failure count, new items per source Adding a new source would be as simple as dropping a config entry with the URL, type (scraper/API/RSS), schedule, and field mappings. No code changes for standard sources. I've built similar aggregators that handle 50+ sources running on a single VPS without issues. Happy to walk you through the architecture before we start — let's chat.

Drawing from my extensive background, I propose a Node.js-based solution for your multi-source aggregator project. Utilizing technologies such as Axios for making synchronous HTTP requests, Cheerio for parsing the fetched data, and Express framework to build the RESTful API – we can ensure a seamless flow of data at a remarkable speed. Through my comprehensive experience with creating data aggregators, I have developed highly effective mechanisms to schedule periodic scraping tasks ensuring no missed updates. The robust error-handling I will implement will handle any ambiguity or breakdown in information sources, making certain that the system remains functional and efficient. With regard to data storage, I recommend using a NoSQL solution like MongoDB which offers flexibility in handling unstructured or semi-structured data. Pairing this with GraphQL would not only allow easy querying of the database but also simplify the customization process should you desire to retrieve particular dataset attributes in the future. In parallel, setting up a lightweight monitoring dashboard using tools such as Winston and Morgan would be both efficient and user-friendly.

Hi, This is right up my alley—I can build you a clean, scalable data aggregator that pulls from websites, APIs, and RSS feeds, normalizes everything, and serves it through a fast, single endpoint. How I’d approach it: Data Collection: • Scraping via BeautifulSoup / requests • API integrations using standard REST clients • RSS ingestion using feedparser Processing Layer: • Normalize all data into a consistent schema • Add metadata (source, timestamp, type) • Deduplicate using hashing + unique constraints Storage: • PostgreSQL (structured + reliable) or MongoDB (if flexibility needed) Backend API: • FastAPI for high performance • REST endpoint returning merged JSON (<1s for 100 items) Scheduler & Reliability: • APScheduler / cron-based jobs • Built-in rate limiting, retries, and error logging Monitoring: • Simple dashboard (Streamlit or minimal web UI) • Logs for fetch status, failures, and updates Deliverables: • Fully working aggregator system • Clean, well-documented code • README (setup in <30 mins, adding new sources) This will be easy to extend, reliable in production, and fast to query. Let’s get started. Best Regards Shubham Sharma

Data Normalization and Storage: I’ll store the aggregated data in a structured format (I recommend NoSQL for flexibility, but I can use SQL if preferred). The data will include metadata such as source, timestamp, and content type. Scheduling and Rate-Limiting: Implement scheduling with proper rate-limiting to ensure responsible polling without missing updates. REST/GraphQL API: Expose the data via a REST or GraphQL API. I’ll also build a simple dashboard/logfile to monitor the status, failures, and new items. Performance Optimization: Ensure merged results are returned in under one second for a 100-item request on standard hosting. I prefer using Python with Scrapy for scraping and FastAPI for the API, but I’m flexible with the tech stack. The solution will be clean, well-commented, and well-documented, with setup instructions for easy deployment. Looking forward to collaborating on this project!
