    I've worked for an ESP (Email Service Provider) in Chicago for the past 9+ years. I build and maintain an array of Linux shell, python and Node.JS scripts as part of my daily role as head of Customer Support. I also contribute to the flask API and AngularJS front end of the the reachmail.com website. My strengths lie in data processing/manipulation, API and web form integrations, and Automation. While my current tasks rely heavily on MSSQL, and Elasticsearch, I am also comfortable with MariaDB, PostgreSQL, MongoDB, and DynamoDB.

    Specializing in Automation Scripting, Bot Development, Web Scrapping, Data Extraction, PowerShell, and Microsoft Azure Automation. Do you need automation or a bot created for your business? Batch Excel/PDF/Document editing? Automatically upload/download files? Scraping website and automatically upload data to Google Drive? A custom form that searches multiple spreadsheets based on form submission? You came to the right place, automation is my specialty! I have been scripting for 10 Years now using PowerShell. It is a great scripting language for web scrapping and automation of any kind. Some automation I have created includes apps such as Google Sheets, SharePoint, Discord, Twitter, Instagram, BattleNet/Steam, and Youtube. I've scrapped a range of websites including sports pages, financial institutions, social media, consumer sites, and many more. I have created a variety of automated scripts/tools as well. I have created scripts to implement fixes and solutions on Windows and macOS environments as well as automate repetitive tasks for business/document processing. Automation is my passion.
