I have implemented ERPNext at more than 15 companies in the logististics, insurance and retail industries; ranging in size from 2 to 90+ employees. I have also built ERPNext modules and customization for companies in the Logistics, Insurance and Manufacturing Industry. Over the years I've gained intimate knowledge of the inner workings of ERPNext, the Frappe framework and the Python and Javascript programming languages. I have also gained working knowledge of Finance, Accounting, Stock Operations, Insurance, Manufacturing and Project Management. Open and regular communication is important to me, it ensures the project is completed to the satisfaction of all parties involved.

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 You may already try services like proxycurl, but more often than not, their data is outdated (scraped months ago).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

    Learning is also a kind of earning. So, I learned Web analytics and completed 200+ projects on Fiverr and Upwork. Then I fell in love with Data Science and learned its all topics by heart along with a master degree in Data Science :) The future belongs to those who learn more and more skills so I believe that when we stop learning, we start dying. However, my existing skills along with a short description are given below. Web Analytics: Certified, experienced and best at web analytics using Matomo and Google Analytics. Web Development: PHP frameworks are my home turf and I have completed so many projects in Opencart, Codeigniter, Laravel, and WordPress. Please have a look at the portfolio to see the projects. Web scraping & crawling: Thanks to the Search Engine development project for which I crawled & scraped 1 million web documents :P so after that I always see myself doing scraping, crawling, and automation-related projects. For automation, I use selenium, beautiful soup, and Python. APIs development: As Python is in my blood so before data science, I used to work on APIs development and web scraping using Python. Big data: I have rich experience in the Hadoop eco-system using Apache Hadoop, Apache Hbase, Apache Nutch, Apache Hive, Apache Solr, etc. The detail is given below. ** Apache Hbase: How to store and retrieve data from Hbase and how to use it with Hadoop and Apache Nutch. ** Apache Nutch: How do search engines work? How to develop your own search engine using Apache Nutch as a crawler, Customization of Nutch at all phases, Tuning of Nutch for effective crawl, and a lot more. ** Apache Solr: How to use Solr for indexing purposes, How to use it in distributed mode, how to do indexing, how to analyze indexed data using different Solr clients. Matomo analytics: There was a time when I was the only Matomo related developer on Fiverr and Upwork. I have very rich experience in following tasks. ** Matomo Installation, configuration, and integration with the website. ** Matomo customization like custom dashboard development i.e., change look & feel different and you can claim that it is your custom product. ** Custom event tracking with/without Matomo tag manager ** Custom variables/dimensions, Goals, and conversions tracking. ** Conversion rate, custom reporting, and GeoIP-based correct location tracking. ** Expert to fetch tracking data through Matomo API to develop a custom dashboard or to display insights on another website.

    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.

    Developer with 4+ years of experience working with a multitude of modern programming languages. With my wide breadth of knowledge, you can rest easy knowing the right technologies are in use for your project. Finding a team to properly write software can be very difficult — I know this first hand. A custom piece of software needs to be developed in a robust, clean, and expandable way. Unfortunately, these details are often an afterthought, and unnecessary time and money is spent to rewrite code when the demand or requirements change. By using extensive study in the field of software design principals and methods I can greatly minimize these risks; saving you money when things change (and let’s face it, they always do). With me you not only get someone who knows the language — you get someone who understands the big picture and how it all fits together in a way that allows your software to grow with your business. Common projects I undertake include: - ETL Pipelines - Full Stack Web Development --- Django --- Flask --- CppRest --- jQuery --- Postgresql --- Mysql --- Memcached --- Redis - Dockerizing - Multi Platform Projects (Windows, MacOS, Ubuntu) --- GUI Applications --- CLI Applications --- Tools and Libraries - Specialized Domain Heavy Applications - Embedded Development --- ESP8266 - Web Automation - Many more

I have done multiple contracts in this area that covers many different types of financial instruments (stocks, options, futures) on different markets (US mostly, but also some European markets). I focus on implementing your strategy, especially hiding from you some of the peculiarities of the IB API, and making the code reasonable simple and robust. I am also taking work that overlap with this, basically: - Python work, mostly around statistics and visualization, usually using Pandas. - Other financial platforms
