That's a sample of feedback on completed jobs, and that's the level of client satisfaction I love to provide. Short CV: My programming professional experience spans over 20 years. In the last 10 years I have been working with Python, focusing on Data projects and applications. I'm extremely experienced with Python, scrappers, pandas, numpy and pretty much any related library. Before that, there is one decade's data-analysis and programming experience. I had been working with data collecting and processing tasks of all sorts using Python and VBA or AppsScript for Microsoft Excel/Google Sheets. I use scripts and professional licensed tools for web scraping (automated website reading), PDF scrapping, and editing, OCR (scrapping from image files, using Tesseract and Finereader), file/data management, 230000+ entries on some projects. I can speak directly to API, or read/parse the HTML output/Dynamic DOM tree. I deploy to cloud (I use Amazon Web Services) for scaling and to perform geo-related searches, completing huge jobs in a few hours. Tech Background: I have extensive SYSOPS experience, having deployed numerous projects in AWS (using Lambda, EC2, S3, SQS etc), server-less and server-native. I speak Python (including frameworks as Pandas, BeutifullSoup, Puppeteer and selenium/webdriver, boto3 for AWS, Django for full stack web applications), VB, VBA (for Advanced excel solutions), Google Apps Script (for Google Docs and sheets based automations), Bash (for Linux SysAdmin tasks), JS, C, HTML, JSON, XML, CSS, and Windows Automation languages (i.e. Autoit, pyauto etc). I have used dozens of frameworks, and hundreds of APIs including Google APIs (geolocation), and Twillio for marketing projects. I have delivered working solutions that use hundreds of proxy servers with management and recycling. In the recent years, I have extensively used and implemented OpenAI's GPT APIs to various web and pc applications. On this front, I have also studied and make myself a pro in prompt engineering, to make GPT actually work without hallucinations. This is an ongoing endeavor. I have developed and deployed web applications based on Python (Django), SQL, Bootstrap5. I have done custom-developed genetic algorithms that perform live optimization, solving problems of trillions possible solutions. I offer services rather than products. I'll design the best applicable solution for your task from scratch, run it on my own infrastructure, and deliver the results to you within time. The solution can also be developed as your own custom Web Application or Software as a Service (SaaS), "fully managed" by me to ensure working for as long as you wish. This means a custom made website or web API that do what you want them to do. Hosted, secured, login-ready, will work on any device (Mobile/Tablet/Mac/Windows/Linux any flavor), at reasonable price for development and maintenance. Also, I'm available for support on short notice, as long as our contract is active. I can also comply with a Service Level Agreement (SLA). Through the years and through different projects and roles I have been in touch with hundreds of businesses and different verticals. The solutions I provide require me to understand the scope, and I find it easy to learn about and understand different subjects, be it Internet Marketing, SERP and SEO, Ships and Shipping Business, Automotive, Agriculture, Financial and Tax, Logistics and Production Lines, Electronics and Robotics, on a level that allows me to easily communicate and requirements of new projects and tasks. I'm a fluent English speaker, and I'm available on Upwork chat even when I'm on mobile. This means I will respond to chat messages immediately or within 2 hours, 5 AM to 8 PM (UTC). I am also available at Skype, Slack, or Teamviewer, upon request (After Hire). I'm a business-minded trained professional that you can count to, to get the job done in the requested time, with 100% accuracy and attention to detail. Contact me today to make it work, together.
