    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.

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 You may already try services like proxycurl, but more often than not, their data is outdated (scraped months ago).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

    I am a Microsoft Certified Professional. If you’re not impressed by my certifications, how about Top Rated Plus and 100% Job Success on Upwork? Still feeling picky? I warmly invite you to explore my work history below, where you’ll find feedbacks from my clients and successful real-life projects they’ve commented on directly on the platform. My professional experience with Microsoft Dynamics 365 Business Central and its predecessor, Microsoft Dynamics NAV, covers more than 12 years. I can implement Business Central for your company or take over your half-implemented solution from an unreliable partner. WANT TO GAIN MORE EXPERIENCE WITH BUSINESS CENTRAL, TRAIN YOUR USERS, AND AUTOMATE THEIR DAILY ROUTINES IN THE SYSTEM? I'm ready to consult your team and share my experience in configuring and operating Business Central in the following areas: financial accounting (chart of accounts, account payables and receivables, bank reconciliation, fixed assets, intercompany transactions, financial consolidation), supply chain management (distribution, warehousing, replenishment), manufacturing and retail (LS Central, LS Nav, LS Hospitality, LS Forecourt from LS Retail). LACKING SOME FEATURE IN BUSINESS CENTRAL OR STRAGGLING FROM IRRITATING ERRORS? With my technical background, I can easily troubleshoot errors, customize the standard functionality to your needs or industry-specific requirements, create bespoke features or modules from scratch, and develop new reports and document templates matching your company's corporate style and identity. I am also experienced with and implemented numerous integrations between Business Central and other on-prem systems and online services (Dynamics 365 for Sales, Magento, InforWM, Quantum Qguar, custom web, and mobile apps, etc.). INTERESTED IN BUILDING YOUR COMPANY'S BUSINESS INTELLIGENCE AND ADVANCED REPORTING? I can help you to expose your Business Central's data to Power BI. Together we can design reporting solutions that can answer questions from your specific business domain or niche, which is not possible with off-the-shelf Power BI reports. Moreover, little or none of such reports can effectively mine Business Central's data, as it requires a deep understanding of the internal data model, while also respecting established data consistency rules. Please do not hesitate to contact me to discuss your upcoming implementation project or desired modifications. I will be more than happy to share my experience and knowledge with you! Looking forward to hearing from you!
