    I've been an IT professional for 25+ years. For the majority of my corporate career I was a one man IT department for a regional property management firm. I managed all aspects of corporate IT including server administration, desktop support, and cybersecurity strategy. Since 2016 I've specialized in Google Workspace administration and am a certified Google Workspace administrator. My largest Google Workspace deployment was over a thousand users and have managed deployments as small as a single user. I have the breadth of knowledge needed to assist your business in maximizing the return from your IT investment. I'm a big believer in the opportunities that automation offers small businesses. I can assist you in streamlining and simplifying repetitive tasks so they're done correctly every single time with very little effort. I have a teaching mindset and am comfortable assisting non-technical users, so if you just want to get something done without all the jargon, I'm happy to do that. Alternatively if you'd like to go into all the details about a topic I'll take you there as well.

    My experience: ━━━━━━━━ 8 years of successful PrestaShop development: ✔️ Theme installation and adjustments ✔️ Module development - any level of complexity ✔️ API integration: shipment, payment (Stripe, Paypal), supplier warehouses, social media integrations, CRM integrations, Prestashop API etc. ✔️ Optimization (caching, server upgrades, debug profiling, DB queries optimization, module adjustments for better performance) ✔️ Long-term support, Emergency support Skill stack, most in use: ━━━━━━━━━━━━ ✔️ PHP 5.6+, C++ as programming languages ✔️ HTML5 (+smarty and twig as templates) ✔️ CSS3 ✔️ JavaScript (jQuery) ✔️ MySQL5.5+ and MariaDB. ✔️ CentOS, Ubuntu, Debian as Server's OS ✔️ Git, Docker ✔️ Frameworks/CMS: Prestashop, Wordpress, Laravel, Simfony, Yii2 Few suggestions on how to improve your Prestashop website, free of charge: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Enable caching - you know, some clients and freelancers often forget about this important built-in tool. It improves your website performance and can significantly speed it up. 2. Enable pretty URLs - it's a part of free of charge SEO built-in PrestaShop. 3. Disable statistic modules - I guess you've already had Google Analytics for this purpose. Disabling modules can help you to improve performance, speed up your admin pages and don't waste your DB memory by writing useless info. 4. Clean up your product and checkout pages - try to focus your client's attention on the main thing - on a product they want to buy. Leave 1 - max 2 blocks of additional products to offer at the end of the page. 5. Don't make your menu complex. Want to understand how much it complex? Ask your friend to find some product without using searching and count how much time it will take. If it takes more than 15 seconds to find the right category - you need to make an urgent review of your site's navigation. 6. Figure out who are your competitors. Figure out how do they attract customer's attention. Implement ready-to-use decisions, which already tested by your competitors. Save your time, money and enjoy benefits.
