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 You may already try services like proxycurl, but more often than not, their data is outdated (scraped months ago).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 have 14+ years of data analysis and programming experience. On a daily basis I work on a variety of tasks. Sometimes I will be focusing on writing many complex SQL queries from scratch. Other times I will be working on a cool complex VBA project for automation. I am all about automation. Everyday I work with data and analyzing it to see what it can tell me. I enjoy the challenge of being inventive and designing a solution to complex problems. Because I do this on a daily basis, I am constantly learning things I didn't know. I am an expert in Excel/Google Sheets and excellent in many different forms of SQL (ex. Oracle, MySQL, Teradata, SQL Server). I am also an expert in visualization. With all the data analysis experience I have learned how to structure data to create the visuals you are looking for. I am an expert in PowerBI, Looker Studio, and AWS Quicksight. Combining all my technical skills with my personality of detailed oriented and proficient in meeting strict deadlines makes me the perfect professional to complete your project.

I have been working in the medical field for the past 10 years revolving around interoperability, integration, and automation. For the past 6 years, I've been focused on Mirth Interfaces with the following design concepts: - HL7 data coming from EMRs/EHRs - Text and CSV files from SFTP servers and Google Cloud Buckets - Data processed and formatted for PACS, Dictation systems, and receiving EMRs/EHRs - Data processed and formatted for warehousing and analytics My experience defining, designing, and integrating with different EMRs revolves around my time at Shasta Networks and Medford Radiology Group. I built and designed interfaces at Shasta Networks for clients that used Cloverleaf and some that even used McKesson. I worked directly with a McKesson engineer while I was at Shasta Networks to incorporate a stored procedure that allowed us to receive updated patient records based on the stored procedure and a specific update to the database for the patient. As for the interfaces at Medford Radiology Group, the majority of our clients were using Epic and it was my responsibility to ensure ADTs, ORMs, and ORUs, passed to the correct systems such as our Fujifilm Synapse PACS, RIS, and Nuance PowerScribe. During my time at Shasta Networks and Medford Radiology Group, I created design documentation to not only help those who may come after me but to help the project move forward more efficiently and to create a better understanding of the workflow and increase clearer communication between me and the other IT teams. There were times that I had to directly work with the client's IT, networking, and interface teams to see a project through from the first kick-off call all the way to go live. I feel that being able to work directly with the client and the teams gave me the ability to gain the experience of communicating with a diverse group of personalities and an understanding that we are all striving for the same goal. I desire to work with companies and clients that strive to create significant and positive changes while having a culture of diversity, respect, and positivity.

With an extensive Upwork client history profile and having been Expert-vetted by Upwork as being in the top 1% of freelancers, I look forward to working with you soon! I am an integrations expert and am able to use tools such as Zapier, Microsoft Power Automate (formerly called Flow), and Make(formerly called Integromat), to create API integrations between many different applications. I have a keen understanding of backend data and how to easily get relevant information from one system to another. Integrating systems on the backend helps business workflow to be simplistic, efficient, and fast. I have been working on integrations since 2016, and have linked together numerous CRMs, accounting systems, marketing systems, spreadsheets, etc in a variety of ways, some simple and some extremely complex. Given API documentation, I am able to build custom connections, triggers, and actions in Zapier for many cloud based applications that do not yet have Zapier integration. Some of my other skills include Javascript, Airtable, Google Sheets, Google Forms, Fillable PDFs, JotForm, Typeform, Fillout Forms, X2CRM, Excel, Canvas, Planning Center, TeamUnify, Amateur Radio Operator, French language. As the owner of Glaive Consulting, I understand the needs of the small business owner to automate as much of the business as possible to allow focus on client work. Task tracking, time tracking and invoicing and customer followup are among some workflows that I have optimized for my business. Let me help you do the same!

I love MS Access and VBA, they've been my passion for over 25 years and I've become a pro at developing amazing apps and automating. My apps are top quality: user-friendly, very well thought out, packed with functionality yet simple to use, and are developed with an eye towards minimal clicking and thinking for the user. Automation and streamlining is a constant theme in everything I do. I believe that you and people in your company shouldn't do ANY manual repeating tasks because they can all be automated. I'm excellent at automation, I will ask a ton of questions to learn your workflow and will then develop an app that will do most of your work for you. I can also do anything you need when it comes to updating existing MS Access applications, automating your workflow, converting Excel sheets to MS Access applications, converting MS Access applications to SQL or to newer versions of MS Access, and writing Excel macros. I'm quick to reply to messages I'm easy to work with, no condescension here :) I have many libraries of reusable VBA code, forms, and reports, which greatly speed up development

I've developed Power BI reports since 2015 in Portland Oregon. Since then I’ve had success (and a ton of fun) creating countless reports and dashboards for various customers in a wide variety of industries including software, insurance, sports equipment, consulting, healthcare, and manufacturing. I also have extensive experience with training others how to develop reports using Power BI and have successfully trained over 50 people with with common tasks and best practices not limited to: data modeling, DAX, creating advanced visualizations, and requirements gathering. I've led successful trainings in a variety of mediums including recorded training modules, one on one deep dives, and in-person and remote group sessions. Lately I have also been focusing on developing self service-reporting models compatible with Excel and Power BI which can be a great option for democratizing reporting in addition to traditional reports. Report renovation is also a skill I have a ton of experience with. Renovation is a great strategy in a variety of scenarios but especially if you have any lingering access/excel reports floating around your organization. Power BI can be a great modernization tool for consolidating, automating, and optimizing these legacy reports all while minimizing cost. Think of it as a home renovation/remodel, your same home restored into good repair and integrated with modern features. Now switch your home with that old excel report that's been around for a decade plus. Reach out today to learn more about renovating your legacy reports! I regularly attend the local Portland Power BI User Group meetings and have even presented a few topics myself. Tools & Languages: Power BI (DAX & Power Query) SQL Server Management Studio (T-SQL) SQL Server Integration Services SQL Server Analysis Services Feel free to check out my Power BI GitHub repository to view some of the capabilities I've developed
