    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 You may already try services like proxycurl, but more often than not, their data is outdated (scraped months ago).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!

    I'm mainly a Web Developer, but one with the experience of working with nearly everything inside and outside of his field. All of my external ventures have had the pleasant effect of allowing me to make connections where most people don't even think to look, and make use of all of my skills to the best of my abilities. I absolutely love thinking outside of the box, and most of my personal projects are just a touch crazy in general; I call them creative. I mainly tend to use Python - Flask, Django, and Tornado - for most of my projects, although I also quite enjoy using Golang these days. I've been using Python for about 5 years now and Golang for around 3. I'm also extremely comfortable with Javascript - Vanilla, Vue, React and Angular, and I have quite a bit of fun working on frontends. That said, I'm not going to say that I'm amazing at coming up with Web Designs since it takes me forever to come up with a design I'm satisfied with; I much prefer to be handed a design to work with. I've never failed a project that I've taken on and I've never taken on a project I'm not sure about finishing successfully. I tend to be extremely straight forward about what I can do and how long it might take me to do it. I know my limits, and I try to break past them every single day. I was raised in Canada, so English isn't a problem by far. I can also converse well in Korean and Spanish, but I wouldn't say that I'm fluent. So yeah, let's have fun.

    I'm here to improve your business. And I hope you are, too. I can help you if want to: ● Move your business forward and upward. Don't just fix issues - raise the bar. ● Get a clear and high return on your investment (ROI) ● Innovate and think outside the box. Isolation suffocates business. My value extends beyond: ⭕️ 360° business perspective You would be working with someone who has seen it from all angles. Today's problems are complex and the best solutions often consider many perspectives. I have helped improve management, engineering, sales, and operations teams by providing advice, ideas, mentorship, and unique research, as well as by designing and creating trainings, onboarding programmes, and internal publications. 🌍 International experience I have lived and worked in the Middle-East, North America, and Europe with people from dozens of countries. The diversity of those experiences has enriched my worldview and business acumen. 💼 Industry experience Although my work is not industry-specific, I happen to have worked in the software, fashion, insurance, digital advertising, and music industries. Reasons you should not work with me: ✖️ You care about deliverables (e.g. report) more than business results (e.g. higher revenue) ✖️ Respect and transparency are not core values. I love working with wonderful people I trust and respect back. If we're not peers, then I won't be able to help you. ✖️ You're shopping for cheap work. My mantra is "Be high-quality, demand high-quality." And we all know the aphorism: what's good ain't cheap. Green flags I look for in a client: ● Open-minded and receptive to new ideas ● Values trusted partnerships ● Focused on business improvement ● Looking to be the best ● Looking for the best About me: A pianist by birth, an engineer by training, and a consultant by curiosity, I improve businesses by applying my creativity, experience, and common sense. My attention to detail earned me the nickname "hawk eyes" (true story - ask me about it). Having lived in, and visited, many countries, I have long learned to look at old things in new ways, new things in old ways, and to appreciate that every audience, place, and time have their own language. In my experience, the best interactions and ideas draw inspiration from different walks of life. ❤️ Think we match? Let's find out! Hit "Hire" or "Invite" in the top-right corner of the page.

    I specialize in architecting and building out systems with Django. I've spent years in the framework, using it to do the heavy lifting for both rapidly building prototypes/MVPs, and careful crafting robust, performant, and scalable production systems. I've designed and built APIs using Django REST Framework, done loads of task-based processing with Celery, and worked with many external systems and integrations. I'm also very comfortable as a full stack software engineer in general. I have React, Vue, and general HTML/CSS/Javascript experience necessary to work across frontend parts of any application. Beyond all of that, I have low-level systems experience and native Android development experience. I also have data science and visualization experience, being familiar with the scientific python stack and D3 JS. I graduated from UC Berkeley in May 2017 with a B.A. in Computer Science and a B.A. in Applied Mathematics.

    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 know you'll probably get a bunch of low-ball bids, but do you really want to risk this project on somebody because they are the lowest bidder? Probably not. You can avoid pitfalls and save yourself time, energy and hassle if you choose a quality developer. You want peace of mind, knowing that the job will be done right the first time. But if anything does go wrong, you want to know that your developer will stand by his/her work and complete the project with integrity. I have over 5 years of website development experience. My strengths are in building and maintaining websites, but I have additional experience in search engine optimization, developing marketing strategies, brand development and social media marketing. I always factor in these important details when crafting strategies and building sites. I have oodles of experience with Wordpress and have even built a sophisticated e-commerce site. Plus, I have an extensive working knowledge of all the tools of the trade - CSS, HTML, PHP,MySQL, JAVASCRIPT and JQUERY. I know how to craft quality websites and if anything goes wrong, I know how to fix it. If you're not just looking for the lowest bid, but want quality work that will last, then I'm your guy.
