    LinkedIn scraping has become extremely difficult in the last few years – especially at Large Scale. Tools like Phantombuster can scrape hundreds of profiles a day – how can you scale it up to tens of thousands a day for your ambitious projects? You may already try services like proxycurl, but more often than not, their data is outdated (scraped months ago). Using Python, I built the "one of its kind" LinkedIn Scraper for large-volume LinkedIn scraping projects. The system allows me to: ✅ Scrape leads from LinkedIn Sales Navigator searches, including verified emails – Big search? No problem! ✅ Extract LinkedIn people profiles ✅ Extract LinkedIn company profiles ✅ Find decision makers of specific companies on LinkedIn, accurately and quickly ✅ Extract current employees of specific companies on LinkedIn ✅ Extract past employees of specific companies on LinkedIn ✅ Extract all member profiles of specific groups on LinkedIn ✅ Scrape LinkedIn job posts ✅ Find companies on LinkedIn based on a list of web domains or company names What makes my LinkedIn Scraping service different? 💯 Real-time information (up-to-date profiles, not cached data) 💯Large volumes of data — up to thousands and millions of profiles 💯 No need for access to your LinkedIn account or Sales Navigator 💯 Fast, accurate, and customized to your specific criteria People who have used my service once come back whenever they need more data: ⭐️⭐️⭐️⭐️⭐️ "Cung is professional and highly capable. He can do things that many others will say are impossible. Worth every penny. Stop scrolling, and start hiring!" – Mark ⭐️⭐️⭐️⭐️⭐️ "Cung is a master. Excellent skills, fantastic communicator, and an exceptionally talented engineer. If he can't do it, nobody can. Highly recommend!" – Spencer ⭐️⭐️⭐️⭐️⭐️ "Cung is just phenomenal! He is fast, reliable, and accurate and needs only to be pointed to a project and set to go. He thinks on his feet, asks just the right questions, and gets the job done. Just fantastic. Thank you, Cung!" – Peter Barry Ready to get started? Send me a message, and let's talk!

    Please Note: I am not available to work through Skype or phone calls at this time. I can only work through Upwork messages or email. ------ Since I was 12, I've been pursuing graphic design and web development both independently and through schooling. I started off building websites using free website generators like MaxPages and Geocities. Since then, I've moved onto custom designs built using Photoshop and Dreamwever on content management systems, like MODx and Wordpress, with standard-compliant coding. Over the years, I’ve had experience with HTML, CSS, Javascript (jQuery), PHP, XML, and MySQL, both as they pertain to content management systems as well as custom-built solutions. I’m experienced with Apache-based hosting platforms and the software that comes with them, like cPanel and PHPMyAdmin. I’ve also worked with AWS and Microsoft hosting platforms on an as-needed basis. One thing I’ve come to love about development is troubleshooting and fixing websites, both in live and test environments. Solving the puzzles of code you’ve never seen before to bring a website back online is incredibly satisfying. In a similar vein, I enjoy performing routine maintenance on websites as it allows me to catch problems before they appear, both from a functionality and security standpoint. In 2016, I began a new venture in content creation, which exists alongside my web development work. Content creation has allowed me to explore new creative avenues like video recording and live streaming using software like Premiere Pro and OBS on platforms like YouTube and Twitch. I’ve also had the opportunity to further my graphic design and web development experience through creating and maintaining a website where I write guides and other articles. My work has required me to be a constant presence on social media. This not only means frequently communicating with people but also making sure the content I’m creating can be displayed or consumed across all social media platforms. I must also perform search engine optimization to ensure my content appears in search results when relevant.

    Websites and interfaces on WordPress using vanilla WP (custom themes) and popular page builders (Oxygen, Elementor, Bricks). I can implement design of any complexity — in a responsive and optimized manner, or work with your existing site. Full-stack (PHP, JS, Node.js, HTML/CSS, Alpine JS, Vue JS). I also design — check my design profile. What I can do for you: — Implement new and port existing designs to Elementor/Oxygen/Bricks or custom theme (or from one builder to another), focusing on responsiveness and page speed. — Develop any extra functionality needed — simple shortcodes, complicated data processing, bookings, calendars, custom widgets, API integrations — you name it. — Fancy and non-standard stuff too. Photobooth on WP with QR codes and sharing page? Check. Custom video player for your royalty free music shop? Check. Marketo integration? Check. You come up with ideas, I come up with solutions. — Configure and run fast, user-friendly and cost-effective WordPress hosting stacks on popular cloud platforms. — Integrate any 3rd party services/APIs with your site — from carts to learning systems to YouTube. Custom YouTube player with transcript and translation switching? Check. Elementor visibility conditions for LearnDash? Check. — Build complex forms and quizzes and push the data from them to any external systems like CRMs, SMS services, payment systems, etc. Niches/companies I worked with: As a developer, I worked with lots of small and medium businesses to help them maintain their existing sites and develop new ones, in niches like hosting, 3D printing, royalty-free stock content, coaching, developer tools, and many more. I also worked as a designer for a number of pretty well-known companies and government institutions — from ISPsystem (hosting panel vendor), Shapeways (one of the US largest 3D printing companies, NYSE-listed) and large hosting companies to small businesses and startups all over the world. Some of my work is NDA-ed, but I'll happily show relevant samples privately. I live in Haifa and don't accept full-time offers, but ready to meet and discuss projects live all over Israel and abroad. Ready to work part-time on monthly contract for better availability and lower response time.

    I am a consultant, developer and architect splitting my time between in Norway and the US specializing in Salesforce.com development, administration and integration and was a Salesforce Developer World Championship Finalist. I currently hold 12 Salesforce.com certifications that can be verified via their certification verification tool online. I have also completed my MBA with UCLA Anderson focusing on marketing, finance and IT/operations management. I have over 10 years of salesforce.com development and architecture experience in advanced administration, cross-platform integration, web integration and workflow process design. I have also designed and built integrations between salesforce.com and PHP websites, Mailchimp, Pardot and Marketo utilizing native integration tools as well as custom-development with the Salesforce.com SOAP and REST APIs.

As you can see from my profile, I have tested in either the top 10%-20% for Salesforce.com, PHP and business strategy, marketing and management.
