Hey there!
I'm Sergey Khakhulin - full stack developer and freelancer with over 20 years of experience.
There are over 10 large CRM/ERP systems where I played roles of software architect and software developer and they were developed from scratch using C# .NET. I have worked as freelancer for several years. This allows me to implement my potential as full stack developer.
Last 16+ years I have provided services of web app development using PHP, JavaScript, JQuery, and CSS 3. I know all popular content management systems such as WordPress, PrestaShop, Shopify and others. I've used successfully Symfony and Laravel platforms in my projects. You can have a look at some of the software applications that I've done on my website.
I have strong skills in all popular databases MySQL, MS SQL, SQLite. Linux and Windows Server administrate is not a problem for me either.
I speak English, Polish, and Russian. So we can easily communicate in any of these languages.
I am open to any kind of work on IT projects: desktop applications, web applications, and mobile applications.
I'm available for freelancing through a company and using freelance platforms Guru and Upwork.
If you need good reliable software, let's work together! :-)
