Founder
2020 - 2023
Goon
- Founded Goon, a premium WordPress plugin that allows you to optimize your WordPress website by allowing you to selectively disable certain unneeded plugins on specific pages or during Ajax requests.
- Created the websites with the most active plugins to benefit from this kind of optimization; for websites with 70+ active plugins, the page loading speed improvements were up to 90%.
- Enabled page loading speed improvements due to the flaws found even in the well-known and widely used popular plugins; a shining example is a popular plugin for contact forms that is actively used on more than 1.5 million websites.
- Observed the plugins that should be blocked on certain requests loading themselves and all of their resources on every page request, not only where they are needed.
- Built Goon to make it possible to block entire plugins with some of their JavaScript and CSS resources if they are not needed.

Technical Consultant | Senior Lead Web Developer
2016 - 2020
Elite Marketing Pro, LLC
- Implemented a major overhaul of the entire system the company was using. Delivered significant improvement in speed, stability, and security. The company didn't previously have quality insights into its metrics.
- Enabled the company to become confident in their new system and expand further which convinced them to do a bigger investment into their IT resources. The company had around 10,000 daily active users.
- Performed a second major overhaul and included a whole set of new features in the system which allowed the company to cut the costs on third-party services they were using till then. This investment saved them $200,000 annually.
- Made contributions that enabled the company to grow further and increase its revenue by 35% in a year. They've reached over 28,000 daily active customers.
- Improved and maintained a complex WordPress multisite system that eligible affiliates used as their daily marketing tool.
- Developed a custom solution that allowed the sales floor to create and pay orders in WooCommerce in the name of the customer. The feature involved creating custom WooCommerce payment gateway and advanced custom usage of Stripe API.
- Created a custom solution that splits a single order into a multi-pay order which allowed the sales floor to split the payment across multiple customers' credit cards from Stripe. One of the split payments could be a PayPal invoice.

My First WordPress Project in 2010
https://web.archive.org/web/2017*/winalite.hrIt was an affiliate eCommerce multilingual website. It has quite a set of features that one would choose as a starting project in a new CMS environment.
Sadly, the company no longer operates at the scope they were at the time, but luckily—an archived version of the website can still be found at the link.
